Nice Weather On Land….Ocean Waters Remain Rough

August 28th, 2014 at 7:08 pm by under General Talk, Tony's Pinpoint Weather Blog

Good Evening From Chief Meteorologist Tony Petrarca…

…HURRICANE CRISTOBAL WILL BRING DANGEROUS SURF AND RIP CURRENTS TO SOUTH FACING OCEAN BEACHES OF RHODE ISLAND AND MASSACHUSETTS THROUGH FRIDAY

HIGH RISK OF DANGEROUS SURF AND RIP CURRENTS. ALSO VIEWERS OF LARGE SURF SHOULD BE IN SAFE AREAS WELL AWAY FROM POSSIBLE SPLASH OVER.

LARGE WAVES CAN SWEEP A PERSON INTO THE WATER FROM WHAT MAY SEEM TO BE A SAFE VIEWING AREA. 

A RIP CURRENT…SOMETIMES MISTAKENLY CALLED AN UNDERTOW…IS A STRONG BUT NARROW CURRENT OF WATER FLOWING FROM THE BEACH TO THE SURF ZONE. IT CAN RAPIDLY CARRY A SWIMMER INTO DEEPER WATER AND EXHAUST AN INDIVIDUAL TRYING TO SWIM AGAINST IT. IF YOU ARE A POOR SWIMMER AND ARE CAUGHT IN A RIP CURRENT…SWIM PARALLEL TO THE BEACH UNTIL OUT OF ITS PULL.

ANOTHER MEANS OF ESCAPE FOR THOSE WHO ARE GOOD SWIMMERS IS TO RIDE THE CURRENT OUT BEYOND THE SURF ZONE WHERE THE RIP CURRENT DISSIPATES…THEN SWIM TOWARD SHORE OUTSIDE THE EFFECT OF THE NARROW RIP CURRENT. DO NOT ATTEMPT TO SWIM BACK TO SHORE DIRECTLY AGAINST THE CURRENT…IT CAN EXHAUST AND DROWN EVEN THE STRONGEST SWIMMER

Swells from Cristobal Have Arrived, High Surf Continues

August 28th, 2014 at 9:07 am by under General Talk

High Surf Advisory continues along our ocean facing beaches today as swells from Hurricane Cristobal have now reached our coastline.  We’ve been watching the surf building through the night and beach surf could reach 6-12ft today, leading to potentially strong and dangerous rip currents.  There were reports of dozens of water rescues yesterday at area beaches and conditions will be worse today, so be extra cautious if heading to the beach. temp 2

temp 1

Hurricane Cristobal is making it’s closest pass today, staying about 300miles south and east of Nantucket, so the only effects felt from the storm are in our waters.  The seas will stay unsettled into Friday with the high surf advisory through at least noon.  There could still be a moderate risk for rip currents into the start of the holiday weekend.

Cristobal to Bring High Surf, Dangerous Rip Currents

August 27th, 2014 at 7:36 am by under General Talk, Tony's Pinpoint Weather Blog

Hurricane Cristobal is continuing on a track that will keep it well off-shore of southern New England with no threat of a landfall. temp 1 However, it is leading to higher surf and an increased risk for rip currents at our beaches over the next few days.  Already today, ocean facing beaches in RI and southeastern MA have a moderate risk for rip currents so be cautious if you are beach bound and plan on swimming.

By this evening, surf will build to as high as 6-9ft and there will be a high risk for rip currents.  In fact, our coastline is now under a “High Surf Advisory” from 8pm this evening through 8pm Thursday.   temp 2

Seas will begin to diminish by Friday and the Labor day weekend as Cristobal moves further away from the area.


11am Cristobal Update

August 25th, 2014 at 11:18 am by under General Talk, Tony's Pinpoint Weather Blog

Cristobal continues to show signs of slow strengthening, but upper-level winds (wind shear) continue to try to tear the system apart.

Cristobal_Vis

The visible satellite picture above clearly shows the center of circulation exposed to the north of the Bahamas.  The strongest of the showers and thunderstorms remain to the east and south of the center.  The central and southern Bahamas are continuing to see heavy rain from the system, and there have been many reports of flooding on the island chain.

At 11am, Cristobal was approximately 715 miles southwest of Bermuda and about 1275miles south of Providence.

Cristobal 8am Update

August 25th, 2014 at 9:31 am by under General Talk, Tony's Pinpoint Weather Blog

Here’s the latest from the National Hurricane Center.  Cristobal was creeping northward away from the Bahamas.  The center was exposed with heavy showers and thunderstorms still impacting the southeast Bahamas.  You can see the ‘feeder bands’ of clouds working into the center of circulation while the brighter white clouds (thunderstorms) are focused to the east and south of the center.

23rd Anniversary of Hurricane Bob

August 19th, 2014 at 1:02 pm by under General Talk, Tony's Pinpoint Weather Blog
HURRICANE_BOB

Courtesy: NOAA

It was 23 years ago this afternoon, on August 19, 1991 that Hurricane Bob made landfall as a Category 2 hurricane in Rhode Island. bobphoto11

It was the last direct hit from a hurricane in southern New England, though we’ve certainly had impacts from tropical systems in recent years–including Tropical Storm Irene and Super Storm Sandy.  Most recently, Hurricane Arthur spoiled our 4th of July with a soaking rainfall as it tracked south and east of Nantucket.

Here’s a great write up from the National Weather Service in Taunton, MA about the effects of the storm in southern New England:

Hurricane Bob developed in the central Bahamas on August 16, then steadily intensified and reached hurricane status on the evening of August 17. Bob continued to strengthen during the next 48 hours, as it began an acceleration north-northeastward, paralleling the East Coast. The eye of Hurricane Bob passed over Block Island, Rhode Island at approximately 1:30 PM, and made landfall over Newport, Rhode Island shortly before 2 PM. 

Hurricane Bob brought sustained hurricane force winds to the immediate coastal communities of Rhode Island and most of southeast Massachusetts. Strong tropical storm force winds blew across the remainder of the region, with many areas receiving gusts to hurricane force east of the Connecticut River. Wind damage to trees and utility poles was common and resulted in numerous power outages. Over 60 percent of the residents across southeast Rhode Island and southeast Massachusetts lost power. Damage was also extensive to apple and peach orchards across these areas.

Coastal communities bore the brunt of the storm, with sustained winds between 75 to 100 mph. Peak wind gusts to 125 mph were recorded on Cape Cod in the towns of Brewster and North Truro, as well as in Wethersfield, Connecticut. The highest sustained wind of 100 mph, was recorded in North Truro. Block Island reported sustained winds of 90 mph, with gusts in excess of 105 mph (maximum speed of equipment). Wind gusts to near 100 mph were recorded in Newport and by the Navy Ship Samuel B. Roberts, which was riding out the storm on the east passage between Newport and Jamestown, Rhode Island. Additionally, there were four reports of tornadoes as Bob came ashore. The lowest barometric pressure was recorded by the USS Valdez while in the east passage of Narragansett Bay, with a reading of 28.47 inches.

Hurricane Bob caused a storm surge of 5 to 8 feet along the Rhode Island shore, but drove a surge of 10 to 15 feet into Buzzards Bay. The Buzzards Bay shore east to Cape Cod was hardest hit. The highest surges, of 12 to 15 feet, were observed in Onset, Bourne, Mashpee and Wareham, at the head of Buzzard’s Bay. Cove Road, in Mattapoisett, Massachusetts had 29 of 37 homes destroyed, while Angelica Point, Massachusetts lost 32 of 35 homes along the shore. Boat damage was significant, as many boats were torn from their moorings. Extensive beach erosion occurred along the shore from Westerly, Rhode Island eastward. Some south facing beach locations on Martha’s Vineyard and Nantucket islands lost up to 50 feet of beach to erosion.

Significant rainfall of 3 to 6 inches fell across all but southeast Rhode Island and eastward to Cape Cod, where less than 1 inch fell. The heaviest rainfall of over 7 inches affected western Rhode Island and extreme eastern Connecticut. Foster, Rhode Island had the highest amount of rain with 7.01 inches.

Bob was responsible for six deaths in the region, all in Connecticut. Total damage in Southern New England was approximately 680 million dollars.

 


Hazy, Hot and Humid–Not This August

August 19th, 2014 at 12:41 pm by under General Talk, Tony's Pinpoint Weather Blog

 

It’s been a delightful summer filled with temperate days, cool nights and low humidity…. which means it’s been lacking much of the sultry air New Englanders either love or loathe.  It’s quite a difference from last year–where we had 16 days hit 90° or higher.  So far this year, we’ve managed to climb to 90°+ just three times–all in early July.  And this month, especially, temperatures are running cool.  Through August 18 temperatures at TF Green Airport are running more than 2° below normal, and  14 of the first 18 days of the month have been at or below normal.  temp 1

This morning lows were the coldest so far this month for many areas, including at TF Green where temperatures dipped to 54° at dawn.  temp 3

I don’t expect any significant spells of hot weather heading into the end of August.  Starting on Thursday and lasting into the weekend, temperatures will be below normal again with highs in the 70s and nights in the upper 50s to lower 60s.  And the outlook for the last week of August from the Climate Prediction Center shows continued cool conditions over much of the northern tier of the country.  temp 1


Monday’s Outlook In S’rn New England and Williamsport

August 18th, 2014 at 12:07 am by under General Talk, Tony's Pinpoint Weather Blog

Outside of a few showers on Sunday, the weekend was pretty nice!  A cold front passed through Southern New England Sunday evening and brought with it some drier air.  High pressure will be building into the Northeast on Monday.  With high pressure, you get sinking air, so it’s harder to get clouds and precipitation.   We’ll stay dry here in Southern New England on Monday with lots of sunshine.

Planetary Conjunction Monday Morning

August 17th, 2014 at 12:04 am by under General Talk, Tony's Pinpoint Weather Blog

There’s going to be an spectacular astronomical phenomenon called a planetary conjunction in the early morning sky Monday morning.  A conjunction is when planets (or any celestial bodies) appear to join together (as seen from Earth).   Earth, Venus and Jupiter will make a near perfect line in space, and this will create a unique show just before sunrise. 

After the sun and the moon, these two planets are the brightest objects in our sky.   Venus and Jupiter will look like a double star as they will appear less then 1/2° apart from each other.  That’s a very small piece of the sky.  The distance between the two will be about the size of a coffee stirrer held at arm’s length!

Despite their close appearance in our sky, the two planets will be very far apart.

Sunday’s Outlook

August 16th, 2014 at 8:49 pm by under General Talk, Tony's Pinpoint Weather Blog

We are expecting some rain showers on Sunday, but we are not looking at a washout.  In fact, many people won’t even be seeing any rain.  There are two time periods for showers that we are watching– early morning and afternoon.

Early Sunday morning we could see some rain showers move in off of the ocean.  They’ll be moving northeastward and areas to the south and east of Providence could be clipped with a few showers.  The Cape and Islands could hear a rumble of thunder, too, as the air will be pretty unstable there.  Below is the computer model HRRR for midnight.   These showers are expected in Southeast New England between midnight and 8am.

Another batch of showers will move into Southern New England from New York…similar timing here as well — midnight to 8am.

Heavy Rain Moves Across RI /SE MA This Morning

August 13th, 2014 at 7:52 am by under General Talk, Tony's Pinpoint Weather Blog

We’ve been watching an incredible flash flood event developing over parts of LI and CT this morning, with more than a foot of rain in Islip, NY on Long Island…. flash flooding has shut down numerous streets and lead to water rescues there.  Check out this photo from the Weather Channel’s Stephanie Abrams:

temp 2

Islip, NY

That band of heavy rain will continue to lift northeast across RI and southeastern MA through the morning and early afternoon.  Our computer models are still indicating the potential for 1-3″ of rain in our area, with isolated higher amounts possible.  Here’s one look at potential rainfall totals from the RPM model this morning.  temp 3


Flash Flood Watch Expanded

August 12th, 2014 at 12:49 pm by under General Talk, Tony's Pinpoint Weather Blog

The National Weather Service has expanded the Flash Flood Watch to include all of RI and southeastern MA except for the Cape and Islands as our computer models continue to show the potential for heavy rain and embedded thunderstorms with a potent storm system moving through New England on Wednesday.

temp 1

We are still forecasting 1-3″ of rain for most of our area, though isolated higher amounts are possible.  Here’s the 12z RPM model precipitation forecast for rainfall totals:  temp 2

In addition, our coastline is now under a “Coastal Flood Advisory” for the potential for minor flooding during tomorrow mornings high tide around 10am-11am.  The combination of an astronomical high tide and a strong southeast wind could cause minor splash over at south and east facing coastlines. temp 3


Wednesday Storm Update

August 12th, 2014 at 9:47 am by under General Talk, Tony's Pinpoint Weather Blog

We’ll squeeze in one more dry day before a storm system moves in and brings heavy rain and embedded thunderstorms to our area starting later tonight and into Wednesday.  We could certainly use the rainfall as parts of our area have been abnormally dry; however, the rain could be heavy enough to overwhelm storm drains leading to localized street and poor drainage flooding along with smaller stream flooding.

The highest risk of seeing flash flooding is across inland parts of southern New England, where rainfall rates of up to 2″/hr are possible. As of this morning, northwest RI and the Boston suburbs were included in a “Flash Flood Watch” for late tonight through Wednesday evening.  temp 1It looks like our best shot of getting widespread rain and thunder will be from mid-morning through late afternoon. In addition, there’s the risk–though small–for some severe thunderstorms.  This morning, the Storm Prediction Center highlighted southern RI and SE MA as an area that could see severe weather tomorrow–with damaging wind gusts and even an isolated tornado possible. temp 1

Finally, we could see some minor flooding along the coast and bay during tomorrow morning’s high tide. High tide in Newport Harbor is at around 10:30am.  The astronomically high tide due to the nearly full moon, combined with a stiff southeast wind may lead to minor flooding.  temp 2


Stormy Day on Wednesday

August 11th, 2014 at 11:21 am by under General Talk, Tony's Pinpoint Weather Blog

As Pete Mangione mentioned  in the previous blog, the ingredients are coming together for a potentially stormy day on Wednesday.  An area of low pressure currently over the Great Lakes will drag a cold front through New England by Wednesday with a new storm developing along the front.

Surface Map valid at 8am Wednesday

Forecast Surface Map for 8am Wednesday

The set up gives us the potential for periods of heavy rain with embedded thunderstorms.  Right now the forecast is for as much as 1-2.5″ of rain in New England.

Forecast Rainfall Amounts for Wednesday

Forecast Rainfall Amounts for Wednesday

Heavy rain could lead to localized street and poor drainage flooding, and potentially some dangerous flash flooding.  In addition, any embedded thunderstorms will bring torrential downpours and possibly damaging winds.  Timing of the heaviest rainfall in Rhode Island and southeastern Massachusetts looks to be Wednesday morning and afternoon…. tapering off in the evening.  Stay tuned for more updates as we continue to monitor this potential severe weather day.


Super Weather This Evening for the Super Moon

August 10th, 2014 at 9:15 am by under General Talk, Tony's Pinpoint Weather Blog

Today will be beautiful here in Southern New England — lots of warm sunshine with low humidity.

Once you’re home from the beach or out of the pool, you might want to check out the “Super Moon” — the closest the moon will be to the Earth this year.  I think the weather will cooperate, too.

There will be a piece of energy dropping down from Northern New England today. You can see it in the image below (yellow, orange and red).

500mb

 

This will help create some rain showers for parts of New Hampshire, Maine and northeastern Massachusetts, but that’s about it.   Any showers should be isolated up there, and they’ll likely stay out of our area.

Cloud-wise for RI and nearby MA, there will be some clouds especially east of Providence.  Our computer models indicate there will be some moisture in the atmosphere at 850mb and 725mb (approximately 5,000 to 8,000feet up).   This will translate into partly cloudy skies this evening.  Below is the relative humidity in the atmosphere all the way up to about 40,000feet.  Notice the pinkish area this evening…that’s high relative humidity over Providence.  I think dry air aloft will help keep our skies in good enough condition to see the moon, especially as it rises.  Times run from left to right on the graph…UTC is Greenwich Mean Time (4hours difference from us).

Another Nice Day on Sunday

August 9th, 2014 at 10:50 pm by under General Talk, Tony's Pinpoint Weather Blog

Saturday’s weather was fantastic, and we’ll get another great day on Sunday.

An area of high pressure will be sliding overhead through the day.  High pressure promotes sinking air, and it’s tougher to make the clouds and therefore tougher to get precipitation.   There will be a little piece of energy in the upper-levels moving southward from Maine/New Hamphire.  This may scare up a few extra clouds across eastern parts of our area, but that’s about it.   We’ll be staying dry.

Fcst_Map3_650x366

Winds will start from the north as the high center builds into New England, but those winds will become more onshore during the afternoon with a developing sea breeze.   Temperatures will be a little cooler at the coast, but it will be nice everywhere with low humidity.  The weather looks good for seeing the “Super Moon” Sunday evening and for Perseid Meteor watching early Monday morning.

Perseid Meteors Peak Next Few Nights

August 9th, 2014 at 9:40 pm by under General Talk, Tony's Pinpoint Weather Blog

One of the best meteor showers of the year will peak August 9-14 — the Perseid Meteor Shower.   They are best seen after midnight and during this time of the summer, it’s comfortable to be outside and stargaze.  In a dark sky, you could see 50 meteors per hour.  This year, we’ll have the full “Super Moon” and waning gibbous moon to dim some of the meteors.

Sometimes you can see a few after 9pm as the constellation Perseus rises over the horizon, but the best show always arrives after midnight.

What are the Perseid Meteors?

Meteors are tiny bits of rock, usually the size of a piece of dust or as large as a pebble, that burn up in the atmosphere as the Earth plows through the debris in space.  They get their name because of the constellation they appear to come from — Perseus.  This debris is actually from a comet, Comet Swift-Tuttle.

Courtesy: NASA

Courtesy: NASA

The comet passes through the inner solar system once every 134 years.  It spends most of its time hanging out past the orbit of Pluto in an area known as the Kuiper Belt — an area of space filled with many pieces of rock, likely left over from the development of the Solar System.  The last visit was in 1992.  During each passage, the comet sheds gases and debris as it gets closer to the sun.  That debris is left floating in space.

Super Moon Sunday

August 9th, 2014 at 8:16 pm by under General Talk, Tony's Pinpoint Weather Blog

Get your cameras ready! This year’s “Super Moon” is coming to a sky near you.  Here in Southern New England, the moon will rise at 7:36pm on Sunday and will appear bigger than other full moons we’ve had this year.

Astronomy_650x366

What is a Super Moon?

The moon has an elliptical orbit around the Earth, and our only natural satellite takes approximately 27 days to make a full orbit around the Earth.  That orbit changes  Because of that elliptical orbit, the moon has both a closest (perigee) and farthest (apogee) distance from the Earth.   During a “Super Moon”, the moon is at its closest approach of the year and appears to be bigger and brighter.   When the moon is the farthest, we call it a “Micro Moon”.  The smaller-looking moon was visible in our skies in January.  The distances change each month throughout the year.

Sky_Watch_650x366

These terms are fairly new in our lingo.  The moon has had this elliptical orbit for eons, but the words “Super” and “Micro” Moons have emerged in just the past few years.  Sunday’s Super Moon isn’t really even the closest the moon can get to Earth.  In March, 2011, the moon was 221,565 miles from us — that’s 126 miles from the smallest Earth-Moon distance.  It was during the days leading up to that perigee that the term “Super Moon” really exploded into our lingo.

In addition, there is a piece of energy moving over Southern New England this afternoon which will work with a weak frontal boundary at the surface to help spark these storms.  You can see the yellow and orange area in the graphic below..

These factors along with the sunshine will all work to help create some scattered thunderstorms this afternoon into the evening.  It won’t be raining all the time, and not everyone will see a storm, but the possibility will be there.  I think the best chance will be away from the immediate south coast; however, all of Southeast New England could see a thunderstorm through the afternoon until about 6-7pm.

They will likely be short-lived, but they could bring:

  • Brief, but heavy rain
  • Gusty winds
  • Hail

High Rip Current Risk for Wednesday

August 5th, 2014 at 5:27 pm by under General Talk, Tony's Pinpoint Weather Blog

Tropical Storm Bertha will be passing approximately 300 miles to the southeast of New England late tonight.  While we won’t be seeing any rain or wind from Bertha, we will see some heavy wave action during the next several days.  The National Weather Service in Taunton has issued an alert for a High Rip Current Risk for ocean exposed shorelines in Southeast New England.  These alerts are issued by the National Weather Service when there is the risk for dangerous rip currents along some area beaches.  Rip currents can become life threatening.

From that alert:

Rip currents are strong and very localized currents of water near the surface which move directly away from the shoreline and through breaking waves.  They can be caused by a number of factors including large waves from passing tropical systems like Bertha.  If you plan on swimming in the water, swim near and within sight of a lifeguard.

When caught in a rip current, swimmers can be quickly carried away from the beach.  If you are caught in one, don’t panic! Swimming against a rip current can exhaust even the best swimmers.  If you are caught in a rip current, it’s important to swim parallel to the shoreline.  If you are headed to the beach, memorize the graphic below.  It could save your life.
