Thursday Morning Update

Erin turning away
Erin is now starting to move away from the US east coast as it pulls away from North Carolina. High surf and strong rip tides remain a concern. Winds and rainfall have not been an issue. IR satellite imagery show that there is still deep convection near the core and also away from the center. A Hurricane Hunter aircraft confirms little change in strength over night, except for a little weakening. Winds at 10,000 ft were measured at 100 knots or 115 mph. A correction factor for surface estimate is 90%, so winds to about 100 mph is an estimate.

Thursday Evening Update

Erin well offshore
Erin is well east of the Mid-Atlantic coast, but caution still should be used on Mid-Atlantic and Northeastern beaches as surf will continue to be higher than normal. A small area of deep convection is near the center of circulation and it will continue to spread as Erin is beginning to become extratropical and should make that transition in the next 24-36 hours.
