TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
800 PM EDT TUE OCT 18 2016

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

1. A non-tropical low pressure system located about 250 miles
northeast of the Turks and Caicos Islands is producing a large area
of cloudiness and thunderstorms that extends from near Puerto Rico
and the Dominican Republic northeastward over the Atlantic for
several hundred miles.  Upper-level winds are forecast to become
more conducive for this system to acquire some tropical
characteristics, and a subtropical or tropical cyclone is likely to
form within the next few days.  The low is forecast to move
northward to north-northwestward on Wednesday and Thursday, before
turning north-northeastward and merging with a cold front over the
western Atlantic by the weekend.  A NOAA Hurricane Hunter aircraft
is scheduled to investigate this system tomorrow afternoon, if
necessary.  Regardless of development, locally heavy rainfall is
possible over the Dominican Republic, Puerto Rico, and the U.S.
and British Virgin Islands tonight and Wednesday.
* Formation chance through 48 hours...medium...60 percent
* Formation chance through 5 days...high...80 percent
