920 AM EDT SUN AUG 24 2008

AN INCREASING ATLC TROPICAL CONSENSUS OCCURRING IN OVERNIGHT RUNS
CONCERNING THE DEVELOPMENT OF 94L AND POTENTIAL INTERACTION WITH
95L. GLOBAL DYNAMICAL MODELS NOGAPS/ECMWF/CMC/UKMET ALL INDICATE
DEVELOPMENT AND A NW TRACK INTO THE BAHAMAS OR CUBA BY DAY 6 WITH
A NW CONTINUENCE. GFS REMAINS ALONE WITH LIMITED TO NO
DEVELOPMENT. HURRICANE MODELS ARE LESS EMPHATIC AND MAINTAIN A
MORE WRLY COURSE TOWARDS CENTRAL AMERICA WITH 94L. WHETHER 94L OR
95L OR BOTH THERE SHOULD BE AT LEAST A TROPICAL WAVE OR GREATER
MOVING INTO THE BAHAMAS OR CENTRAL GREATER ANTILLES DAYS 5-7
POSSIBLY AFFECTING FLORIDA NEXT WEEKEND. SEE TPC DISCUSSIONS AND
ADVISORIES.

HPC UPDATED MORNING BLENDS USE A 50/50 BLEND OF OP GFS AND ECMWF
THRU DAY 5 THEN A BLENSD OF ECMWF AND ECMWF MEAN THRU DAYS 6 AND
7. THE OP 00Z GFS IS REASOANBLE ENOUGH TO USE ALSO AT THIS TIME
BUT WAS NOT USED BECAUSE OF ITS DISREGARD OF TROPICAL SYSTEMS 94L
AND 95L.
