CHANGES WITH THIS ADVISORY: The Bermuda Weather Service has discontinued the Tropical Storm Watch for Bermuda. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches of warnings in effect.

WIND: Locally gusty winds are possible on Bermuda today.

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).

Satellite imagery and radar data from Bermuda indicate that the central convection associated with Ana has changed little in organization during the past several hours, with a complex of small bands near the center at this time. The initial intensity will be held at 40 kt based on the latest intensity estimate from TAFB, although recently-received ASCAT data suggests this could be a little generous. Although the cyclone has some characteristics of a tropical cyclone, Ana remains a subtropical storm based on its position near the center of a large upper-level low pressure system and the current lack of anticyclonic upper-level outflow.

The initial motion is 270/3. Ana and the large low it is embedded in are expected to turn northward later today as a developing mid-latitude cyclone over eastern Canada and the New England states erodes the subtropical ridge west of Ana. After that, the storm is expected to turn northeastward on the southeast side of the mid-latitude cyclone. The track guidance is in good agreement with this scenario, and the new track forecast is similar to, but a little slower than, the various consensus models.

Little change in strength is expected for the next 12 h or so. After Ana recurves, a combination of increasing shear, dry air, and decreasing SSTs should cause the storm to gradually weaken tonight and Sunday. The large-scale models agree upon Ana opening up into a trough of low pressure in 36-48 h, and the official forecast shows this happening just after 48 h. The remnant trough will likely be absorbed by a cold front associated with the mid-latitude cyclone shortly thereafter.
