Epsilon Intensifies to a Hurricane

Former Tropical Storm Epsilon intensified into a hurricane on Tuesday night. At 11:00 p.m. EDT on Tuesday the center of Tropical Storm Epsilon was located at latitude 28.5°N and longitude 56.8°W which put it about 545 miles (875 km) east-southeast of Bermuda. Epsilon was moving toward the northwest at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h). The minimum surface pressure was 987 mb.

A Tropical Storm Watch was in effect for Bermuda.

Former Tropical Storm Epsilon continued to strengthen on Tuesday night. An eye formed at the center of Epsilon. A ring of thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Hurricane Epsilon. Storms near the core generated upper level divergence which pumped mass away to the east of Epsilon. Winds to hurricane force extended out 25 miles (40 km) from the center of circulation. The broader circulation around Hurricane Epsilon was large, especially on the northern side. Winds to tropical storm force extended out 300 miles (500 km) on the northern side of Epsilon. Winds to tropical storm force extended out 100 miles (160 km) in the southern half of Epsilon.

Hurricane Epsilon will move through an environment that will be favorable for intensification during the next 24 to 36 hours.  Epsilon will move over water where the Sea Surface Temperature is near 28°C.  It will be in an area where the upper level winds are weak and there will be little vertical wind shear.  Some drier air may wrap around the southern side of the circulation, but the drier air is not forecast to penetrate to the core of the hurricane. Epsilon could intensify during the next 24 hours to 36 hours.

Hurricane Epsilon will move around the southwestern part of ridge of high pressure over the Northeastern Atlantic Ocean.  The ridge will steer Epsilon toward the northwest during the next 24 hours.  Epsilon will move more toward the north when it moves around the western end of the ridge. On its anticipated track Hurricane Epsilon could pass east of Bermuda on Thursday night.
