000 ABNT20 KNHC 172341 TWOAT Tropical Weather Outlook 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, Newfoundland. 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. 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. $$ Forecaster Berg
