Re: Bahamas system

The low level center is now over the gulf stream devoid of deep convection just west of Andros, i believe the mid level to the east near off cat island is actually what we should be watching, the low level will hit run into florida and weaken at wich point the mid level will try and drop down over water. As it also moves northwest to just offshore southeast florida or over grand bahama island.

Re: Bahamas system

The OOOOz models are a bit disconcerting. Looking like the invest will not turn as soon as thought. Wonder if NHC revises its track of invest. Looks to be a very wet weekend if models are right. Then once over gulf who knows what will happen then.

Just realized the shaded area that the NHC shows for an invest is potential area of development not track. If 98 were a TD S Fla would be in the center of the track cone. Most of the wet weather with 98 is on the east side of the low center so if it tracks more to the west we will have a wetter weekend but the shaded area will stay over water because it would never transition to a TD over land.

Watching the radar last night 98L was literally right on top of S FL, you could clearly see the rotation. A real good representation of an area of a "broad low pressure". Normally these things are so far out to sea you only see the visible satellite of the clouds, but this time with radar you could see multiple small thunderstorms all chasing each in a loop.
