Morning Tropical Update

TD Ana –  is currently located at 17.3N 66.2W or about 75 miles south of San Juan, Puerto Rico. Ana has winds of 35 mph and is moving WNW at 28 mph. Very fast !! She is putting up a good fight. Some models indicate that she may head our way by mid-week as a tropical depression. Currently, she is south of Puerto Rico and has the possibility of emerging off the NW corner of Puerto Rico. At that point, she may get her act together since she won't be over land AND water is warmer. Also, Ana is small in size and storms like those get their act together much faster than a large storm. In other words, if Ana does not interact with of PR or Hispañola, she has a good chance of coming alive again. The water is very warmer in the Bahamas and conditions will be favorable for development. Keep your eye on Ana, she still has a pulse.

 

Hurricane Bill – is located at 14.1N 45.2W or about 1080 miles east of the Lesser Antilles. Bill has winds of 90 mph and is moving WNW at 16 mph with a central pressure of 977 mb. He is still scheduled to curve out to sea later in the forecast due to a weakness in the high pressure system that currently is steering him. A good sign of when the turn will happen is when Bill forward movement slows down. Once that happens, a turn is imminent. Models are in good agreement so the NHC is also on board with it. The NHC says that Bill will become a major hurricane (>111 mph) by Wednesday. I expect it to happen sometime late tonight or the latest by Tuesday 11 AM. It only needs 21 mph more to get there. Bill has been moving a bit north of due west for the last 12 hours, but models are still confident that a weakness wil occur and Bill will curve of to sea.

 

TD Claudette – the NHC has issued their last advisory on this storm. It made landfall last night near the eastern end of St. Rosa island, just southeast of Fort Walton Beach, FL around 1:10 AM EST. Winds were at 50 mph.

 

I will have another update later in the afternoon.
