SPECIAL TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
425 PM EDT TUE OCT 21 2014
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
Special outlook to update first system
1. An Air Force Reserve reconnaissance aircraft did find a small well-
defined low in the southern Bay of Campeche. However, the
thunderstorms associated with the low are still not organized enough
for this system to be considered a tropical cyclone. Upper-level
winds could become more conducive for further development by
tomorrow, and this system has the potential to become a tropical
cyclone before it moves inland over the Mexican state of Campeche
late Wednesday or early Thursday. Later in the week, tropical
cyclone formation appears unlikely due to interaction with
a cold front while the system is over the northwestern Caribbean
Sea. Interests in Campeche and elsewhere in the Yucatan Peninsula
should monitor the progress of this system as tropical storm
warnings could need to be issued with short notice.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...50 percent.
2. A large non-tropical low is located over the far eastern Atlantic
Ocean a few hundred miles south of the Azores. This system is
producing winds of gale-force and could acquire some subtropical
characteristics during the next day or so while it moves west-
southwestward at about 15 mph. 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.
