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 before reaching the Windward Islands.

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).
