On the forecast track, Elsa will pass near or over portions of the Windward Islands or the southern Leeward Islands this morning, move across the eastern Caribbean Sea late today and tonight, and move near the southern coast of Hispaniola on Saturday. By Sunday, Elsa is forecast to move near Jamaica and portions of eastern Cuba.

Maximum sustained winds have increased to near 60 mph (95 km/h) with higher gusts. Some additional strengthening is forecast over the next 12 to 24 hours, followed by little change in strength.

Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center.

The estimated minimum central pressure is 1001 mb (29.56 inches).
