For the North Atlantic…Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on Tropical
Storm Florence, located inland over extreme eastern South Carolina,

western Azores, and on Tropical Storm Joyce, located about
900 miles west-southwest of the Azores.

1. The remnants of Issac, now a tropical wave, are located over the
central Caribbean Sea. Slow re-development of this system is
possible during the next couple of days as it moves
west-northwestward into the northwestern Caribbean Sea. After that
time, upper-level winds are expected to become less conducive for
re-development. Locally heavy rains and gusty winds are forecast
over portions of Hispaniola, Jamaica, and eastern Cuba during the
next couple of days.
* Formation chance through 48 hours…low…20 percent.

10 am (Cayman time) Tropical Storm Isaac updated

At 1100 AM, the center of Tropical Depression Isaac was located near latitude 14.9 North, longitude 67.3 West. The depression is moving toward the west near 16 mph (26 km/h), and this general motion with some decrease in forward speed is expected over the next couple of days.  A turn to the west-northwest is possible early next week if Isaac survives.  On the forecast track, Isaac will move over the eastern and central Caribbean Sea during the next few days.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Isaac is forecast to gradually weaken over the next few days, and could degenerate into a tropical wave at any time.  A NOAA Hurricane Hunter aircraft is currently en route to investigate the depression.

The estimated minimum central pressure is 1007 mb (29.74 inches).
