The Hurricane Hunters flew into the storm and found those max winds at 60 mph and the pressure drop. The NHC denoted in their discussion that some satellite estimates indicated the intensity of Ernesto may be higher. The aircraft will be in the storm later this evening to confirm if perhaps we have a stronger storm. Regardless, Ernesto is still looking good structurally and is expected to feed off the environment it is in: low shear, very warm temps….and we could have a hurricane tonight.

The latest track pulls Ernesto’s enter over the Virgin Islands this evening and then northeast and north of Puerto Rico through tonight and Wednesday. Beyond that point, a trough will interact with the storm and pull it north to northeast well off the US Coast. The track really hasn’t changed in the extended outlook and Bermuda is still in the crosshairs with possible impacts Friday night and Saturday.
