Significant non-tropical storm to affect Florida and East Coast over the weekend

It appears that quite a potent storm is going to take shape over the eastern Gulf of Mexico this weekend as upper level energy digs in from the Great Plains. A surface low is forecast to form over the eastern Gulf and bring the potential for very heavy rain and severe weather to portions of Florida (figure 1).

From there, the low is forecast to move up the East Coast, bringing with it wind and rain all the way to New England. For coastal areas, this will be basically a warm (relatively speaking) Nor’easter. If this were January, we would probably be looking at an epic snowstorm for a good deal of the East Coast. As it stand now, a decent rain event looks to be in store for a wide swath of the Florida peninsula all the way up to Maine with coastal areas experiencing rough seas and a stiff onshore flow (figure 2).

The storm is non-tropical in nature but will tap warm Gulf of Mexico water that is itself running well above normal for this time of year. This warm water will add energy and moisture to the storm system and provide the fuel for it to strengthen and dump copious amounts of rain along its track. If you have outdoor plans this weekend in Florida all the way to New England, keep up to date on the latest weather forecast for your area.

One excellent tool to understand the impacts better of any storm event is to read the local forecast discussion from your National Weather Service office. You can find this by going to www.weather.gov and typing in your ZIP Code. Then scroll down on the landing page to find “Forecast Discussion”. It will have detailed meteorological information with timing, impacts and projected watch/warning info for any storm event forecast for your area. It’s a great tool, use it.
