Fay Transitions to a Tropical Storm

Thunderstorms developed near the center of Fay and an inner core of convection formed.  The thunderstorms released enough latent energy in the middle and upper troposphere to create a warm core.  As a result the structure of Fay changed from a subtropical storm into a tropical storm.  At 11:00 a.m. EDT the center of Tropical Storm Fay was located at latitude 27.9°N and longitude 65.3°W which put it about 305 miles south of Bermuda.  The maximum sustained wind speed was 70 m.p.h. and the minimum surface pressure was 991 mb.

The upper level outflow around Fay is well developed on the west side of the circulation.  It is over warmer Sea Surface Temperatures and some further intensification is possible.  When Fay gets farther north it will run into stronger upper level winds from the west.  Those winds will generate wind shear and start to weaken the storm.

Fay is moving around the western end of a subtropical high pressure system and it should continue to move northward today.  Eventually the upper level westerly winds will force Fay to turn toward the northeast.

The Tropical Storm Watch for Bermuda has been changed to a Tropical Storm Warning.
