For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 200 PM AST (1800 UTC), the center of Tropical Storm Don was located near latitude 11.5 North, longitude 58.7 West. Don is moving toward the west near 20 mph (31 km/h). This general motion is expected through Wednesday. On the forecast track, the center of Don will move across the Windward Islands later today or tonight, and then move westward across the southeastern Caribbean Sea on Wednesday. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Little change in strength is forecast before Don moves through the Windward Islands. The tropical storm is forecast to degenerate into a trough of low pressure over the southeastern Caribbean late Wednesday or Wednesday night. Tropical-storm-force winds extend outward up to 35 miles (55 km) from the center. The estimated minimum central pressure is 1011 mb (29.86 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected in the warning area by late this afternoon and tonight. Tropical storm conditions are possible in the watch area beginning later today. RAINFALL: Don is expected to produce total rain accumulations of 3 to 6 inches, with isolated higher amounts across Barbados, Trinidad and Tobago, and the southern Windward Islands through Wednesday. These rains could produce life-threatening flash floods and mudslides, especially in mountainous areas. NEXT ADVISORY ------------- Next complete advisory at 500 PM AST. $$ Forecaster Brown

Tropical Storm Don Forecast Discussion Number 4
2017-07-18 16:56:08| National Hurricane Center (Atlantic)
Issued at 1100 AM AST Tue Jul 18 2017 000 WTNT45 KNHC 181456 TCDAT5 Tropical Storm Don Discussion Number 4 NWS National Hurricane Center Miami FL AL052017 1100 AM AST Tue Jul 18 2017 Reports from an Air Force Reserve reconnaissance aircraft indicate that the tropical storm has weakened this morning. The highest flight-level and SFMR observations support an intensity of 30-35 kt and the data also show that the circulation has become less defined and in fact it may lack a closed surface circulation. Advisories are being maintained for now pending another reconnaissance aircraft mission later today. Increasing westerly shear and dry mid-level air are likely to continue to weaken the tropical cyclone as it moves through the Windward Islands and the eastern Caribbean during the next day or so. The NHC forecast calls for Don to weaken to a tropical depression in about 24 hours and degenerate into a an open wave within 36 hours. This could occur much sooner than indicated below. The track forecast reasoning remains unchanged. Don should continue to move quickly westward within the strong trade wind flow until dissipation occurs. The NHC track forecast is similar to the previous advisory and is near the model consensus.
