Isaac has become a tropical storm again as it tracks through the Caribbean Sea, but it may not hold intact much longer.

Isaac was centered about 215 miles south of Santo Domingo in the Dominican Republic as of Friday night, moving westward.

Tropical Storm Isaac is battling strong winds in the upper atmosphere, along with dry air. This may cause Isaac to weaken to a tropical depression by Sunday, then degenerate into a tropical wave early next week.

"However, this is an uncertain prediction," the National Hurricane Center said late Friday afternoon, encouraging interests in Jamaica to monitor the progress of Isaac.


Current Status

Isaac is expected to produce additional rainfall amounts of 2 to 3 inches, with isolated maximum totals up to 5 inches, across southeastern Puerto Rico.

Rainfall totals of 1 to 2 inches, with maximum amounts up to 3 inches, are possible across the remainder of Puerto Rico, the Virgin Islands, the Leeward Islands and the northern Windward Islands.

Rainfall totals of 2 to 3 inches, with isolated maximum amounts up to 4 inches, are possible across the south-central portion of the Dominican Republic, southwestern Haiti and most of Jamaica, except for the eastern portion of Jamaica, where rainfall totals of 2 to 4 inches and maximum amounts of 6 inches are possible.

This rainfall may cause life-threatening flash flooding.


Projected Path

Even if Isaac falls apart during the next few days, we will continue to monitor its remnants for any possible regeneration.
