Hurricane force winds are forecast to be experienced from Chatham, MA south to Chincoteague, VA, including the tidal Potomac, north of Cobb Island to Smith Point, the middle & upper Chesapeake Bay, Delaware Bay, Long Island Sound, the coastal areas of Rhode Island, Connecticut, New Jersey, and the northern portions of the Delmarva peninsula.

Tropical storm force winds are forecast for Chatham, MA north to Merrimack, MA and from Chincoteague, VA, south to Duck, NC, along with the lower Chesapeake Bay.
Storm surge forecasts are listed below:
– 1-3 ft in the middle & upper Chesapeake,
– 2-4 ft in the lower Chesapeake and Tidewater area of Virginia,
– 6-11 ft along Long Island Sound and Raritan Bay,
– 4-8 ft from Ocean City, MD north to Connecticut-Rhode Island border,
– 3-6 ft from Connecticut-Rhode Island border east to south shore of Cape Cod, and

The storm surge combined with higher neap tides will bring significant coastal erosion and rip tides. Flooding from both storm surge and heavy rain (see map below) is a major concern as the storm moves into Pennsylvania and New York. The other map that’s included is the rainfall totals until 2 PM ET today.
At 10 PM CDT, Tropical Storm Isaac was located near 30.3°N, 91.2°W, about 15 miles south of Baton Rouge, LA. Isaac has maximum sustained winds of 60 mph and is moving northwest at 6 mph.
A Tropical Storm Warning remains in effect from the Cameron, LA to the Mississippi/Alabama border.
A Tornado watch is in effect for southeast Louisiana, southern Mississippi, and southwest Alabama til midnight CDT.
Isaac continues to slowly work its way across southern Louisiana. Continued heavy rain with associated flooding will be the major issues.
My apologies for the lack of updates at a critical time. My day job as a meteorologist and dad responsibilities kept me very busy.
At 10 PM CDT, Tropical Depression Debby was located at 29.0 N 82.8W, about 20 miles east-southeast of the Cedar Key, FL and is moving southeast at 6 mph. Maximum sustained winds are near 35 mph. TDebby continues to move northeast and is now forecast to continue in a generally northeast and then east track towards the Florida peninsula.
The forecast models continue to move Debby to the east for the next 2-3 days and moves it to the northeast once over the open waters of the Atlantic. Some redevelopment to a tropical storm is forecast at that time too.
