Hurricane DOLLY


ZCZC MIATCDAT4 ALL
TTAA00 KNHC DDHHMM
HURRICANE DOLLY DISCUSSION NUMBER  10
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   AL042008
500 PM EDT TUE JUL 22 2008
 
DOLLY IS BEING CLOSELY MONITORED BY THE NWS RADAR FROM
BROWNSVILLE...NOAA BUOYS..SATELLITE AND VERY IMPORTANTLY...BY AN
AIR FORCE HURRICANE HUNTER AIRCRAFT. THE RADAR IS MEASURING 75
KNOTS AT ABOUT 20 THOUSAND FEET AND SHOW NUMEROUS RAINBANDS ALREADY
APPROACHING THE COASTS OF NORTHEAST MEXICO AND SOUTHERN TEXAS.
DVORAK ESTIMATES SUGGEST THAT DOLLY IS A HURRICANE AND WIND DATA
JUST RECEIVED FROM THE RECONNAISSANCE AIRCRAFT HAVE CONFIRMED IT.
INITIAL INTENSITY IS 65 KNOTS. WITH THE PREVAILING LOW
SHEAR...DOLLY IS FORECAST TO REACH THE COAST A LITTLE BIT STRONGER.
 
DOLLY IS MOVING TOWARD THE NORTHWEST OR 305 DEGREES AT 9 KNOTS.
THIS GENERAL TRACK SHOULD CONTINUE FOR THE NEXT 24 HOURS WITH A
SMALL DECREASE IN FORWARD SPEED. ON THIS TRACK...THE CORE OF DOLLY
SHOULD BE NEAR THE US/MEXICO BORDER WITHIN THE WARNING AREA ON
WEDNESDAY. DOLLY IS LARGE CYCLONE AND TROPICAL STORM FORCE WINDS
WILL BEGIN TO AFFECT THE AREA TONIGHT. AFTER LANDFALL...DOLLY
SHOULD TURN MORE TO WEST AS A SUBTROPICAL RIDGE BUILDS TO THE NORTH
OF THE CYCLONE. MOST OF THE TRACK MODELS ARE IN GOOD AGREEMENT
BRINGING THE CORE OF DOLLY INLAND IN ABOUT 24 HOURS. IT SHOULD BE
RE-EMPHASIZED THAT...DUE TO THE INHERENT UNCERTAINTIES...ONE MUST
NOT FOCUS ON THE EXACT LANDFALL POINT IN THIS FORECAST.
 
DUE TO THE SLOW MOTION AT LANDFALL...DOLLY COULD DUMP VERY HEAVY
RAINS IN THE AREA.
