Tropical Weather Outlook Text


200 AM EDT SUN SEP 13 2015

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

1. Minimal shower and thunderstorm activity is continuing in
association with the remnants of Tropical Storm Grace over the
northeastern Caribbean Sea.  Upper-level winds are not expected to
be favorable for redevelopment of this system during the next
several days.  However, locally heavy rains and gusty winds are
still possible across portions of Puerto Rico, Hispaniola, Cuba, and
the Bahamas during the next day or two while the system moves
west-northwestward at 15 to 20 mph.
* Formation chance through 48 hours...low...near 0 percent
* Formation chance through 5 days...low...near 0 percent

2. Shower activity has increased over the past 24 hours in association
with a tropical wave located several hundred miles southwest of the
Cape Verde Islands.  Environmental conditions are forecast to be
favorable for development, and a tropical depression could form
during the next several days while the system moves west-
northwestward to northwestward across the central tropical Atlantic.
* Formation chance through 48 hours...low...30 percent
* Formation chance through 5 days...high...70 percent

3. A small low pressure system located about 950 miles southwest of
the Azores is producing disorganized shower and thunderstorm
activity.  Development, if any, of this low is expected to be slow
to occur while it moves westward to west-northwestward at about 10
mph over the next couple of days.
* Formation chance through 48 hours...low...10 percent
* Formation chance through 5 days...low...10 percent
