Re: TD 19 Forecast Lounge

If you read the 5pm discussion on this storm the models have shifted west now then the east which they were.

All in all it will be a few days before we can say ANYTHING about where it is gonna go.And that means from Florida to texas to nowhere.Here is the 5pm part i am talking about.



Tropical Storm Richard Discussion Number 4


Statement as of 5:00 PM EDT on October 21, 2010




The best estimate of current motion is about 155/3. A trough over
the western Atlantic and northwestern Caribbean has been steering
the system slowly southeastward during the past day or so.
However... this trough is in the process of lifting out of the
area...which will allow a ridge to build over the Gulf of Mexico.
While the models are in reasonable agreement on the storm
eventually turning back toward the west in a day or so...they are
in rather poor agreement after that time due to varying ridge
strengths over the Gulf of Mexico. All of the forecast guidance has
shifted well toward the left...after moving toward the right
overnight. Given the erratic behavior of the model guidance...a
luxury the official forecast does not have...this is a low
confidence track forecast. The model consensus is actually now in
good agreement with the previous NHC track...and little change will
be made to the NHC forecast. The new 48-hour forecast point is
close enough to Honduras to warrant a tropical storm watch.
