The center of Hurricane Larry passed east of Bermuda on Friday afternoon. Bands on the western edge of Larry’s circulation brought rain and gusty winds to Bermuda. Hurricane Larry was still a well organized hurricane. A circular eye was present at the center of Larry. The eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the center of Hurricane Larry. Storms near the center of circulation generated upper level divergence that pumped mass away to the north of the hurricane.
The circulation around Hurricane Larry was large. Winds to hurricane force extended out 90 miles (145 km) from the center of Larry. Winds to tropical storm force extended out 220 miles (350 km) from the center of circulation. The Hurricane Intensity Index (HII) for Hurricane Larry was 13.9. The Hurricane Size Index (HSI) was 25.4 and the Hurricane Wind Intensity Size Index (HWISI) was 39.3.
Hurricane Larry will move through an environment that should allow it to maintain its intensity during the next 24 hours. Larry will move over water where the Sea Surface Temperature is near 28˚C. It will move around the eastern side of an upper level trough over the eastern U.S. The trough will produce southwesterly winds that will blow toward the top of Larry’s circulation. Those winds will cause some vertical wind shear. However, the winds in the lower levels will also blow from the southwest. So, there will not be a lot of vertical wind shear. Hurricane Larry will move over cooler water when it moves north of the Gulf Stream on Friday. Larry will begin to make a transition to an extratropical cyclone when it gets north of the Gulf Stream.
The upper level trough over the eastern U.S. will steer Hurricane Larry toward the northeast. On its anticipated track Larry will move quickly away from Bermuda. Hurricane Larry could reach southeastern Newfoundland on Friday night. Larry will bring strong winds and locally heavy rain to parts of Newfoundland.
Elsewhere, former Tropical Storm Mindy dropped locally heavy rain over the southeast coast of the U.S. on Thursday morning. At 11:00 a.m. EDT on Thursday the center of Tropical Depression Mindy was located at latitude 31.5°N and longitude 80.7°W which put it about 45 miles (75 km) south-southeast of Savannah, Georgia. Mindy was moving toward the east-northeast at 21 m.p.h. (33 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1005 mb.
