A large upper level low pressure system interacting with  the northern end of a tropical wave has produced a subtropical cyclone.  A reconnaissance plane investigated the system this afternoon and found that it had enough organization to be classified as a subtropical storm.  At 5:00 p.m. EDT the center of Subtropical Storm Fay was located at latitude 24.7°N and longitude 64.0°W, which put it about 525 miles south of Bermuda.  Fay was moving toward the north-northwest at 12 m.p.h. The maximum sustained wind speed was 40 m.p.h. and the minimum surface pressure was 1002 mb.

Fay is moving around the western end of a high pressure system located to its east.  It should turn more toward the northeast when it gets farther north and start to feel the influence of the midlatitude westerlies.

Fay currently has the typical hybrid structure of a subtropical cyclone the consists of one long band that coils about half to three quarters of the way around the system.  More thunderstorms are developing closer to the center of circulation.  If an inner core of thunderstorms develops and they release enough energy into the middle and upper levels of the storm to create a warm core, then Fay could make a transition to a tropical storm.

Fay is over warm Sea Surface Temperatures which create a potential for intensification, but it is also experiencing some wind shear from the nearby upper level low.  It could intensify some, especially if it develops an inner core.  Wind shear will increase as Fay moves farther north and it gets closer to upper level westerly winds.

A Tropical Storm Watch has been issued for Bermuda.
