This morning Invest 90L became Subtropical Storm Ana. This is the first storm of the 2021 season, which doesn’t officially start until June 1st.
At 1100 AM AST (1500 UTC), the center of Subtropical Storm Ana was located near latitude 34.3 North, longitude 63.0 West. The storm is moving toward the west near 3 mph (6 km/h). A turn toward the north at a slow forward speed is expected later today, followed by a faster motion toward the northeast Sunday and Monday. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Little change in strength is forecast today, but gradual weakening is expected tonight and Sunday. Ana is expected to dissipate in a couple of days. Winds of 40 mph extend outward up to 105 miles (165 km) mainly to the north of the center. The estimated minimum central pressure is 1006 mb (29.71 inches).
Subtropical storms are different from tropical storms, in that the maximum winds occur relatively far from the center (greater than 60 nautical miles) and have a less symmetric wind field and distribution of convection.
