Tropical Depression FOUR (Text)

ZCZC MIATCDAT4 ALL
TTAA00 KNHC DDHHMM
TROPICAL DEPRESSION FOUR DISCUSSION NUMBER   2
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
5 AM EDT TUE JUL 05 2005
 
SATELLITE PRESENTATION HAS CONTINUED TO IMPROVE DURING THE PAST
SEVERAL HOURS. THERE IS VERY DEEP CONVECTION NEAR OR OVER THE
CENTER AND THE OUTFLOW HAS CONTINUED TO EXPAND IN ALL QUADRANTS.
THERE IS NO SHEAR AHEAD OF THE CYCLONE SO A GRADUAL STRENGTHENING
IS INDICATED...AND THE DEPRESSION COULD BECOME A HURRICANE IN THE
WESTERN CARIBBEAN SEA. THIS IS CONSISTENT WITH SHIPS AND THE GFDL
MODELS. 

THE DEPRESSION APPEARS TO BE MOVING TOWARD THE WEST OF 280 DEGREES
AT 15 KNOTS AROUND THE PERIPHERY OF THE SUBTROPICAL RIDGE. THE
CYCLONE SHOULD CONTINUE ON THIS GENERAL TRACK WITH A GRADUAL
DECREASE IN FORWARD SPEED BEYOND 3 DAYS..AS IT REACHES THE WESTERN
END OF THE RIDGE. A TURN MORE TO THE NORTHWEST SHOULD THEN BEGIN.
THIS TRACK WOULD BRING THE SYSTEM OVER CUBA AND THE EASTERN GULF OF
MEXICO LATER IN THE PERIOD. THIS IS CONSISTENT WITH MOST OF THE
DYNAMICAL GUIDANCE WHICH IN FACT...IS IN VERY GOOD AGREEMENT.
