NWS NATIONAL HURRICANE CENTER MIAMI FL
200 PM EDT SUN AUG 28 2016
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
The National Hurricane Center is issuing advisories on Hurricane
Gaston, located about 600 miles east of Bermuda, and on newly
formed Tropical Depression Eight, located about 400 miles southeast
of Cape Hatteras, North Carolina.
1. Shower and thunderstorm activity has begun to increase near and to
the east of a weak area of low pressure located just south of the
lower Florida Keys. The low is expected to move westward into the
southeastern Gulf of Mexico on Monday, where environmental
conditions are expected to become more conducive for development,
and a tropical depression is likely to form within the next few
days. This system is then expected to move slowly northward and
northeastward over the eastern Gulf of Mexico later this week.
Regardless of development, heavy rainfall and gusty winds are likely
to continue over portions of the northwestern Bahamas, central and
western Cuba, the Florida Keys and portions of southern Florida
through Monday. Interests elsewhere in Florida and the eastern Gulf
of Mexico should continue to monitor the progress of this
disturbance.
* Formation chance through 48 hours...medium...60 percent
* Formation chance through 5 days...high...80 percent
