NWS National Hurricane Center Miami FL
800 PM EDT Thu Aug 17 2017
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
The National Hurricane Center is issuing advisories on Tropical
Storm Harvey, located a couple of hundred miles east of the Windward
Islands, and has issued the final advisory on Post-Tropical Cyclone
Gert, located several hundred miles east-southeast of Cape Race,
1. Shower and thunderstorm activity associated with an area of low
pressure located about 1000 miles east of the Leeward Islands have
changed little in organization during the past several hours.
However, only a slight increase in the organization of the shower
activity could lead to the formation of a tropical depression during
the next couple of days before upper-level winds become less
favorable for development early next week. The low is expected
to move west-northwestward at about 20 mph during the next few
days, and interests in the northern Leeward Islands should monitor
the progress of this disturbance.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...70 percent.
2. A tropical wave located over the far eastern Atlantic Ocean a few
hundred miles west and southwest of the Cabo Verde Islands
continues to produce disorganized showers and thunderstorms.
Gradual development of this system is possible through the middle
of next week while the wave moves westward to west-northwestward at
about 20 mph.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...30 percent.
