An area of disturbed weather (91L)
, located about 250 miles east-northeast of Cape Hatteras North Carolina, has shown a modest increase in heavy thunderstorm activity this morning. QuikSCAT imagery
from last night revealed a closed surface circulation, but top winds of only 20 - 25 mph.
The disturbance is over the relatively warm waters of the Gulf Stream (25°C) and has wind shear of 10 - 15 knots over it, and these conditions are marginally favorable for some slow development to occur until this evening, when the system will begin moving over waters too cold to support tropical cyclone development. The disturbance will track northeastward at 15 mph today, and and is not a threat to any land areas. In a Special Tropical Weather Outlook
issued at 8am EDT this morning, NHC gave 91L a low (less than 30% chance) of developing into a tropical depression.Figure 1.

Tropical disturbance 90L dropped as much as two feet of rain over Northeastern Florida last week, causing severe flooding. In Volusia County
, at least 1500 homes were damaged by the flooding, and many of these were in low-income housing projects where the residents did not have flood insurance. Portlight Strategies, Inc., is now working to assist in this area by providing durable medical equipment to the disabled, elderly, or injured that have lost equipment due to the flooding. Equipment will also be provided to local shelters and other organizations working with flood victims. To help out, visit the Portlight disaster relief blog.
