Elsa is moving toward the west-northwest near 26 mph (43 km/h) and this motion is expected to continue for the next couple of days. On the forecast track, Elsa will pass near or over portions of the Windward

Recent satellite wind data indicates that maximum sustained winds have increased to near 50 mph (85 km/h) with higher gusts. Some additional strengthening is forecast over the next 12 to 24 hours.
Recent satellite wind data also indicates the tropical-storm-force winds now extend outward up to 140 miles (220 km), mainly to the north of the center. NOAA Buoy 41040, located more than 200 miles north of the center of Elsa, recently reported a wind gust of 38 mph (61 km/h).
