DISCUSSION AND OUTLOOK
———————-
At 500 PM AST (2100 UTC), the center of Tropical Storm Gonzalo was located near latitude 9.8 North, longitude 49.4 West. Gonzalo is moving toward the west near 13 mph (20 km/h). A westward to west-northwestward motion with an increase in forward speed is expected through the weekend. On the forecast track, the center of Gonzalo will approach the southern Windward Islands Friday night and move across the islands Saturday and Saturday evening.

Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Some strengthening is forecast during the next day or two, and there is still a chance that Gonzalo could become a hurricane. Weakening is expected after Gonzalo moves into the Caribbean Sea.

Gonzalo is a tiny tropical storm, and tropical-storm-force winds extend outward up to 25 miles (35 km) from the center.

The estimated minimum central pressure is 1000 mb (29.53 inches).

HAZARDS AFFECTING LAND

WIND: Hurricane or tropical storm conditions are possible within the respective watch areas on Saturday.

RAINFALL: Gonzalo is expected to produce total rain accumulations of 2 to 5 inches, with isolated maximum amounts of 7 inches in Barbados and the Windward Islands from Friday night through Sunday night. Gonzalo is also expected to produce total rain accumulations of 1 to 2 inches in Trinidad and Tobago. Rainfall in Barbados and the Windward Islands could lead to life-threatening flash floods.
