Florida hurricane News weather

Three Waves Expected To Become Cyclones Over Next Several Days.

National Hurricane Center outlook for Wednesday, September 15, 2021.


BOCA RATON, FL ( (Copyright © 2021 MetroDesk Media, LLC) — There is an 80 percent that a system east of Florida becomes a cyclone within 48 hours, and 90 percent chance that it happens within five days.

The system just off the coast of Africa, is still several days from being anything that Florida, or the eastern seaboard, should be concerned about — but it is certainly something to watch.

Forecasters at the National Hurricane Center are also watching a wave that has a 60 percent chance of formation over two days — and 70 percent over five days — as it appears to run parallel to the east coast.

A third system is expected to emerge from the coast of Africa over the next several days.

We remind our readers that ovals represent a possible area of development, not necessarily a direction of travel. This is the early morning outlook from the National Hurricane Center for Wednesday, September 15th, 2021:

located a few hundred miles south of the Cabo Verde Islands continue 
to show signs of organization.  Environmental conditions are 
expected to remain conducive for development, and a tropical 
depression is likely to form during the next couple of days while 
the system moves generally westward at about 15 mph across the 
eastern tropical Atlantic Ocean.

* Formation chance through 5 days...high...90 percent.

2. A trough of low pressure located a few hundred miles northeast of 
the central Bahamas is producing a large area of disorganized 
showers and thunderstorms.  Environmental conditions appear 
marginally conducive for gradual development during the next few 
days, and a tropical depression is likely to form while the system 
moves north-northwestward to northward across the western Atlantic. 
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...high...70 percent.

3. A tropical wave is expected to emerge off of the west coast of
