Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Sat Aug 19 2017
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
The National Hurricane Center is issuing advisories on recently
downgraded Tropical Depression Harvey, located over the central
Caribbean Sea.
1. Showers and thunderstorms remain disorganized near a trough of low
pressure located a couple of hundred miles north of the northern
Leeward Islands. Environmental conditions are not expected to be
conducive for development of this system during the next couple of
days while it moves west-northwestward at 15 to 20 mph. Conditions
could become slightly more conducive for development once the system
is near the northern Bahamas or Florida around the middle of next
week.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.
2. A tropical wave located about a thousand miles east of the Lesser
Antilles is producing a large area of cloudiness but limited
showers and thunderstorms. The wave is currently embedded in a
dry air mass, and upper-level winds are expected to become too
strong to support development in a couple of days. Therefore,
tropical cyclone formation is not likely while this system moves
northwestward at about 15 mph.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.
