Hurricane DEAN


ZCZC MIATCDAT4 ALL

HURRICANE DEAN DISCUSSION NUMBER  36
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   AL042007
1100 PM EDT TUE AUG 21 2007
 
DEAN APPEARS TO BE DEVELOPING A LARGE RAGGED EYE ON SATELLITE
IMAGERY. AN AIR FORCE PLANE REACHED DEAN AND MEASURED A MINIMUM
PRESSURE OF 979 MB AND FLIGHT LEVEL WINDS OF 84 KNOTS.
HOWEVER...THE SFMR HAS ONLY MEASURED 59 KNOTS SO FAR.  SINCE DEEP
CONVECTION IS RETURNING...THE INITIAL INTENSITY IS KEPT AT 70
KNOTS...WHICH IS A BLEND OF BOTH MEASUREMENTS AND DVORAK T-NUMBERS.
DEAN IS FORECAST TO RESTRENGTHEN BEFORE LANDFALL BUT IS RUNNING OUT
OF TIME TO BECOME A MAJOR HURRICANE.  AFTER LANDFALL...THE SURFACE
CIRCULATION SHOULD RAPIDLY BECOME DISRUPTED OVER THE HIGH TERRAIN
OF CENTRAL MEXICO...ALTHOUGH MOISTURE FROM DEAN COULD SPREAD
NORTHWARD.
 
DEAN IS MOVING TOWARD THE WEST-NORTHWEST OR 285 DEGREES AT 16 KNOTS
AROUND THE PERIPHERY OF A STRONG HIGH PRESSURE SYSTEM. THIS GENERAL
MOTION IS EXPECTED TO CONTINUE UNTIL LANDFALL SINCE THE STEERING
CURRENTS ARE NOT FORECAST TO CHANGE.
 
THE MEXICAN NAVY AUTOMATIC STATION LOCATED AT CAYO ARCAS RECENTLY
MEASURED SUSTAINED WINDS OF 46 KNOTS...GUSTS TO 63 KNOTS AND A
MINIMUM PRESSURE OF 986.3 MB. NOAA BUOY 42055 IN THE SOUTHWESTERN
