Tropical Storm Dexter passed north of Bermuda on Monday evening.  At 11:00 p.m. EDT on Monday the center of Tropical Storm Dexter was located at latitude 36.8°N and longitude 65.6°W which put the center about 315 miles (415 km) north of Bermuda.  Dexter was moving toward the northeast at 13 m.p.h. (21 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 1002 mb.

An upper level trough near the east coast of the U.S. was producing strong westerly winds that were blowing toward the top of Tropical Storm Dexter.  Those winds were causing strong vertical wind shear.  The wind shear was affecting the structure of Dexter’s circulation.  Thunderstorms were occurring in bands in the eastern side of Tropical Storm Dexter.  Bands in the western side of Dexter’s circulation consisted primarily of showers and lower clouds.

The strong vertical wind shear and the asymmetrical distribution of thunderstorms were also affecting the distribution of wind speeds in Tropical Storm Dexter.  Winds to tropical storm force extended out 90 miles (145 km) in the eastern side of Dexter’s circulation.  The winds in the western side of Tropical Storm Dexter were blowing at less than tropical storm force.

Tropical Storm Dexter will move through an environment unfavorable for intensification of a tropical cyclone during the next 24 hours.  Dexter will move over water where the Sea Surface Temperatures are near 27°C.  The upper level trough near the east coast of the U.S. will continue to cause strong vertical wind shear.  The strong wind shear will prevent Tropical Storm Dexter from intensifying.  Dexter could get stronger when it starts to make a transition to an extratropical cyclone.

The upper level trough near the east coast of the U.S. will steer Tropical Storm Dexter toward the east-northeast during the next 24 hours.  On its anticipated track, Tropical Storm Dexter will move farther away from Bermuda.
