Florida hurricane News weather

Atlantic Hurricane Season Continues Through November.

National Hurricane Center outlook for early Monday, October 11th, 2021.


BOCA RATON, FL ( (Copyright © 2021 MetroDesk Media, LLC) — The National Hurricane Center is watching two new tropical waves with the potential to form southeast of Florida.

Any interaction with the United States mainland — if there is in any interaction — is several days away. The waves, for now, have reduced chances of development over the next several days.

The waves are represented by the yellow “x” above. The ovals, which are also represented on the map, indicate where a tropical system may form — not necessarily a direction of travel.

This is the early morning outlook from the National Hurricane Center for Monday, October 11th, 2021.

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

1. A non-tropical low pressure area located just off the North 
Carolina coast continues to produce some disorganized showers and 
thunderstorms.  Although this system is not expected to become a 
tropical or subtropical cyclone, locally heavy rainfall and gusty 
winds are still possible over portions of the North Carolina Outer 
Banks today and information on these hazards can be found in 
products issued by your local National Weather Service Office. 
Additional information on this low pressure system, including gale 
warnings, can be found in High Seas Forecasts issued by the National 
Weather Service.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...near 0 percent.

2. A tropical wave located about 400 miles east-southeast of the 
Windward Islands continues to produce disorganized cloudiness and 
thunderstorms.  Some slow development is possible during the next 
day or two while the system moves west-northwestward at about 15 mph 
toward the Lesser Antilles.  After that time, strong upper-level 
winds are expected to limit further development.  Regardless of 
development, the system could produce locally heavy rainfall and 
gusty winds across portions of the central and northern Lesser 
Antilles on Tuesday, and across the Virgin Islands and Leeward 
Islands on Wednesday.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...30 percent.

3. Another tropical wave located over the eastern Caribbean Sea is 
producing a large area of disorganized cloudiness and showers. 
Unfavorable upper-level winds are expected to limit development 
over the next day or so, but environmental conditions could become a 
little more conducive for some gradual development of the system 
when it is located near the southeastern Bahamas around midweek. 
Regardless of development, locally heavy rainfall is possible over 
portions of the Lesser Antilles, Puerto Rico, and Hispaniola during 
the next couple of days. 
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.
