5-28







 Station 42039 with a sustained wind of 38.9kts and gusts of 50.5 kts.

Tyndall tower seeing a few hours of minor TS storm winds of 40kts gusts to 47kts

Apalachicola buoy with TS force gusts to 40kts and sustained just under at 32kts.

Panama city buoys are still under TS for even gusts.

5-27 - been a little busy to post but as in the pre season post, we were at risk of a TS developing in the Gulf.  Alberto was named yesterday.  Currently 50mph winds.  Open on the east side, dry air keeping this from making hurricane strength.  Recon did put out a vort message with a 71mph wind, which hasn't been mentioned by the NHC
