Friday Afternoon Update

Danielle classified as a hurricane
There was only moderate deep convection northwest of the center and weak convection to the southeast. Despite this NHC raised the winds to 75 mph late this morning because of a 52 kt ASCAT wind found to the east of the center. Personally, I would not strengthened it quite as much that soon. By late this afternoon convection has finally wrapped around the center.

Saturday Afternoon Update

Danielle weakens slightly
Dry air has influenced Danielle and caused some slight weakening. Similar to yesterday, the weakest portion of the circulation is to the southeast of the center. Some marginal deep convection is seen to the north and southwest. Models indicate some strengthening is possible if Danielle can fight off the dry air.

Monday Midday Update

Danielle weakens
Satellite imagery shows that deep convection no longer wraps around the whole circulation and I believe that the wind estimate by NHC is generous. Deep convection is noted on the western side of the circulation with a break to the northeast.

Danielle weakens
Danielle is officially a minimal hurricane, although it seems a touch weaker as the eye has filled with clouds. Deep convection has been limited by the cooler sea surface temperatures in the area.

Wednesday Afternoon Update

Danielle still impressive on satellite imagery
Deep convection near the circulation center is warming and moving farther from the center. This indicates transitioning to an extratropical cyclone. Despite this, Danielle has an impressive satellite impression as it continues to by fueled by the Gulf Stream.
