Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Mon Sep 13 2021

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

The National Hurricane Center is issuing advisories on Tropical
Storm Nicholas, located over the western Gulf of Mexico.

A tropical wave is expected to emerge off the west coast of Africa
later today.  Environmental conditions are forecast to be conducive
for gradual development of this system thereafter, and a tropical
depression is likely to form by late this week while it moves
westward at 10 to 15 mph across the eastern tropical Atlantic Ocean.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...high...70 percent.

An area of low pressure is forecast to form by midweek a couple of
hundred miles north of the southeastern or central Bahamas as a
tropical wave interacts with an upper-level trough.  Some gradual
development of this system is possible thereafter, and a tropical
depression could form later this week while the system moves
north-northwestward or northward across the western Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...50 percent.

Showers and thunderstorms remain very limited in association with a
non-tropical area of low pressure over the far northeastern
Atlantic, about midway between the Azores and Portugal.  Tropical or
subtropical development of this system is no longer expected while
it moves eastward and then inland over Portugal by late Tuesday.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...near 0 percent.
