TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
800 AM EDT TUE OCT 21 2014

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

Satellite images and surface observations indicate that the area of
low pressure in the southern Bay of Campeche has become better
defined. Although the associated showers and thunderstorms are
currently not well organized, this system has the potential to
become a tropical cyclone during the next day or so while it moves
slowly eastward toward the western Yucatan Peninsula.  Later in the
week, the low is forecast to interact and possibly merge with a
frontal system over the southeastern Gulf of Mexico or northwestern
Caribbean Sea.  An Air Force Reserve reconnaissance aircraft is
scheduled to investigate the disturbance this afternoon. Interests
in the Yucatan Peninsula should monitor the progress of this system.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...50 percent.

A large non-tropical low is located over the far eastern Atlantic
Ocean a few hundred miles south-southeast of the Azores. This system
is producing winds of gale-force and could gradually acquire some
subtropical characteristics during the next day or so while it moves
slowly westward.  Upper-level winds are forecast to become less
conducive for subtropical or tropical cyclone formation by Thursday
and development after that time is not likely. Additional
information on this system can be found in High Seas Forecasts
issued by Meteo France.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.
