It is time for Tropical Storm watches to be going up and they have for the Northern Leeward Islands. Hurricane Danny has continued to weaken and you can see on the loop above that the storm has lost its intense circular look from yesterday. Shear is beginning to take its toll on the hurricane and top winds are 90 mph. The forecast is for Danny to weaken to a tropical storm by the time it gets to the Leewards and it could weaken even faster than forecast if the wind shear continues to rip it apart.

nhcprogThe forecast track takes Danny over Puerto Rico and north of the Dominican Republic to the southern Bahamas. The weaker the system, the more it will be pushed along by low level eastelies and the main track takes it to the southern Bahamas as a depression.

gfs120Now let’s suppose that the forecast is right. The upper air pattern forecast by the GFS by early Thursday shows a deep trough in the east that is forecast to linger there for a day or 2. If that is the case the likely track would be around the high and then northeastward and away from the coast. At least that is the way it looks right now. Still a long way to go and a lot can happen before we get there.
