Re: Hurricane Watches up For NC/VA, Warnings Later Today

Quote:

A 2nd dropsonde, this one in the outgoing eyewall, read 927mb surface pressure / 104kt surface winds. That is 5mb lower than the vortex recon reported the eye being only a few moments earlier. Weird.

Earl is shedding outer convective bands. Generally you only see this when a storm is becoming annular. Everyone needs to watch this storm very closely. Microwave shows no sign of an ERC to weaken the storm anytime soon.




And the second drop was in the western eyewall of a 30nm eye. Did see a note about the eye being open to the south. If Earl closes that opening the pressure will continue to drop and windspeed will increase later tonight.
