Tropical Storm (TS) Don, the fourth named Storm for the 2017 Atlantic Hurricane Season formed near the Windward Islands on July 17, 2017. TS Don impacted Grenada, St. Vincent and the Grenadines and sections of Trinidad and Tobago during Tuesday night, July 18, 2017. TS Don accelerated westward as it approached Grenada around 8:00pm at a speed of 23 mph (37km/h) and brought maximum sustained winds near 40 mph (65km/h) with higher gusts.


According to the National Hurricane Center, Miami Florida, as at 11:00pm (AST) Tuesday July 18, 2017, TS Don degenerated to an open wave over the far southeastern Caribbean Sea.


Data from an Air Force Reserve reconnaissance aircraft indicated that Don no longer has a center of circulation. At 1100 PM AST (0300 UTC), the remnants of Don were located near latitude 11.9 North, longitude 62.5 West. The remnants are moving quickly toward the west near 25 mph (41 km/h), and this motion is expected to continue during the next couple of days.

The aircraft data indicate that maximum sustained winds are near 40 mph (65 km/h) with higher gusts. These winds are occurring over the waters of the far southeastern Caribbean Sea. Tropical-storm-force winds extend outward up to 45 miles (75 km) to the north of the center.
