A low pressure system associated with former Tropical Storm Beryl reorganized north of Bermuda on Saturday and the National Hurricane Center designated the system as Subtropical Storm Beryl. At 2:00 p.m. EDT on Saturday the center of Subtropical Storm Beryl was located at latitude 36.4°N and longitude 65.7°W which put it about 575 miles (930 km) south-southwest of Halifax, Nova Scotia. Beryl was moving toward the northeast at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1010 mb.
The remnants of former Tropical Storm Beryl moved slowly across the northern Caribbean Sea and then over the southeastern Bahamas to a position northwest of Bermuda. A low pressure system formed at the surface. Bands of showers and thunderstorms developed and began to revolve around the the low pressure system. The low pressure system moved under the eastern side of an upper level trough. The trough contains colder air in the upper levels and it was also producing southwesterly winds which were blowing toward the top of the surface low pressure system. The southwesterly winds were generating moderate vertical wind shear and the strongest rainbands were occurring on the eastern side of the surface low. Some drier air was moving around the western and southern part of the upper level trough, which may have contributed to the weaker bands on the western side of the circulation. The presence of the upper level trough and the asymmetrical distribution of thunderstorms around the surface low prompted the National Hurricane Center to designate the system as a subtropical storm.
Subtropical Storm Beryl will move through an environment marginally favorable for intensification during the next 24 hours. Beryl will move over water where the Sea Surface Temperature is near 26°C. The upper level trough will continue to produce moderate vertical wind shear. The wind shear and the drier air will inhibit intensification. Subtropical Storm Beryl could intensify a little more during the next 24 hours. Beryl will move over colder water later on Sunday and it will start to weaken when that occurs.
The upper level trough was steering Subtropical Storm Beryl toward the northeast and a general motion in that direction is forecast to continue for several more days. On its anticipated track Subtropical Storm Beryl will pass south of Nova Scotia on Sunday. Beryl could be near Newfoundland by Tuesday.
