Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Sun Aug 16 2020
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
The National Hurricane Center has issued the last advisory on
Post-Tropical Cyclone Josephine, located a couple of hundred miles
north of San Juan, Puerto Rico.
1. Shower and thunderstorm activity has continued to increase in
association with a fast-moving tropical wave located about 500 miles
east of the Windward Islands. This disturbance is expected to move
westward at about 20 mph during the next few days, and that fast
forward speed is likely to limit significant development while the
system approaches the Windward and southern Leeward Islands on
Monday, and moves across the eastern Caribbean Sea on Tuesday.
After that time, however, the system is expected to move more slowly
westward across the central and western Caribbean Sea, where
upper-level winds could become more conducive for the development of
a tropical depression during the middle-to-latter part of this week.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...50 percent.
2. Another tropical wave located over the far eastern tropical Atlantic
well to the southeast of the Cabo Verde Islands is producing a large
area of cloudiness and disorganized showers. The wave is forecast
to move westward at 15 to 20 mph during the next few days, and
environmental conditions are expected to become more conducive for
the development of a tropical depression during the middle-to-
latter part of this week while the system moves across the central
tropical Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...50 percent.
