Perfect Storm of 1991 versus SandyOctober 26th, 2012 at 1:51 pm by petemangione under Tony's Pinpoint Weather Blog
There has been a lot of talk about comparing Sandy to the Perfect Storm of 1991. There are some similarities by also some differences, so let’s go over them.
HOW THEY ARE THE SAME
During the Perfect Storm, Hurricane Grace merged with a front moving from the central US. High pressure in the far northern Atlantic acted like a block, which kept the storm from moving further out to sea. In fact, the storm started to move west back towards the land.
A similar situation exists for Sandy. According to most of our forecast computer models, a front moving in from the Great Lakes will merge with Sandy. High pressure in the Northern Atlantic is forecasted to stop the storm from moving out to sea. Instead, it is expected to move back towards land.
HOW THEY ARE DIFFERENT
The most important difference between the two storms is the location of the storm. While the Perfect Storm created widespread damage, the center of the storm never made landfall in New England. (It finally made landfall in Nova Scotia). Here is a satellite photo of the Perfect Storm swirling in the ocean.
Sandy is forecast to make landfall, here is the forecast track from the National Hurricane Center:
While the Perfect Storm wreaked havoc on much of New England, Sandy’s path of destruction for inland areas could be larger because of its expected landfall.
The Perfect Storm deepened to 972 mb, and some of our computer models for Sandy are showing pressure deepening to around 950 mb. This suggest that Sandy could potentially be stronger than the Perfect Storm.
The forecast for Southern New England is highly dependant on the path of Sandy. If she makes a close pass just to our west, Sandy’s destruction could be worse than the Perfect Storm. If she stays far to our south, Sandy would not be quite as bad at the Perfect Storm. Stay tuned!
