Tropical Depression Five Strengthens into Tropical Storm Edouard

Former Tropical Depression Five strengthened into Tropical Storm Edouard northeast of Bermuda on Sunday night.  At 11:00 p.m. EDT on Sunday the center of Tropical Storm Edouard was located at latitude 37.2°N and longitude 56.9°W which put it about 685 miles (1100 km) south-southwest of Cape Race, Newfoundland.  Edouard was moving toward the northeast at 35 m.p.h. (56 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 1008 mb.  Tropical Storm Edouard became the earliest fifth named storm to form over the Atlantic Ocean during the satellite era since 1966.

Former Tropical Depression Five exhibited greater organization on satellite imagery and the National Hurricane Center designated the system as Tropical Storm Edouard.  More thunderstorms formed in bands east of the center of circulation.  Bands in the northern and western parts of Edouard consisted primarily of showers and lower clouds.  Winds to tropical storm force were occurring within 60 miles of the center in the southeastern quadrant of Tropical Storm Edouard.  The winds in the other parts of Edouard were blowing at less than tropical storm force.

Tropical Storm Edouard will move through an environment that could allow for a little more intensification during the next 12 hours.  Edouard will move over water where the Sea Surface Temperature is near 24°C.  It will move under the southern fringe of the upper level westerly winds in the middle latitudes.  Those winds will blow toward the top of the circulation and they will cause moderate vertical wind shear.  The relatively cool water temperatures and moderate vertical wind shear will limit future intensification.  Tropical Storm Edouard could get a little stronger on Monday.  Edouard will move over cooler water later on Monday and it will start a transition to an extratropical cyclone.

Tropical Storm Edouard will move around the northern side of a subtropical high pressure system over the Atlantic Ocean.  The high will steer Edouard toward the northeast.  On its anticipated track Tropical Storm Edouard will pass well south of Newfoundland.
