Subtropical Storm Ana formed northeast of Bermuda on Saturday morning. At 8:00 a.m. EDT on Saturday the center of a Subtropical Storm Ana was located at latitude 34.2°N and longitude 64.5°W which put it about 180 miles (290 km) northeast of Bermuda. Ana was moving toward the west-southwest at 3 m.p.h. (5 km/h). The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h). The minimum surface pressure was 1006 mb.

A Tropical Storm Watch was in effect for Bermuda.

More thunderstorms developed near the center of a low pressure system northeast of Bermuda on Saturday morning and the National Hurricane Center designated the system as Subtropical Storm Ana. Thunderstorms were also occurring in bands southwest and northeast of the center of Ana. Bands in the northwestern and southeastern parts of the circulation consisted primarily of showers and lower clouds. The strongest winds were occurring in the northern half of Subtropical Storm Ana. Winds to tropical storm force extended out 200 miles (320 km) to the north of the center of circulation. Winds in the southern half of Ana were blowing at less than tropical storm force.

Subtropical Storm Ana will be in an environment only marginally favorable for intensification during the next 24 hours. Ana will move over water where the Sea Surface Temperatures are near 23°C. It will be near the center of an upper level low. The winds are weak near the center of the low and there will be little vertical wind shear. Some drier air will wrap around parts of the circulation and the drier air will inhibit the development of thunderstorms. Subtropical Storm Ana could get a little stronger on Saturday. An upper level trough near the East Coast of the U.S. will move toward Ana. The trough will produce southwesterly winds which will cause the vertical wind shear to increase on Sunday. More vertical wind shear will cause Ana to start to weaken.

Subtropical Storm Ana is forecast to remain relatively stationary on Saturday while it is near the center of the upper level low. The upper level trough near the East Coast will steer Ana toward the northeast on Sunday. On its anticipated track the center of Subtropical Storm Ana is forecast to remain northeast of Bermuda.
