Tropical Storm EARL


ZCZC MIATCDAT2 ALL
TTAA00 KNHC DDHHMM
TROPICAL STORM EARL DISCUSSION NUMBER   8
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   AL072010
500 AM AST FRI AUG 27 2010
 
EARL HAS GENERALLY CHANGED LITTLE IN ORGANIZATION DURING THE LAST
SEVERAL HOURS. DEEP CONVECTION THAT REFORMED AROUND 00 UTC HAS
PERSISTED IN BROAD CURVED BANDS MAINLY TO THE WEST OF THE ESTIMATED
LOW-LEVEL CENTER POSITION. SATELLITE INTENSITY ESTIMATES ARE 45 KT
AND 35 KT FROM TAFB AND SAB...RESPECTIVELY...AND THE INITIAL
INTENSITY WILL BE HELD AT 40 KT.  THE ATMOSPHERIC AND OCEANIC
ENVIRONMENTS APPEAR FAVORABLE FOR INTENSIFICATION...AND INDEED ALL
OF THE INTENSITY MODELS SHOW EARL STRENGTHENING THROUGHOUT THE
FORECAST PERIOD. THIS IS REFLECTED IN THE NHC OFFICIAL FORECAST
WHICH BRINGS EARL TO HURRICANE STRENGTH WITHIN 2 DAYS AND SHOWS
ADDITIONAL STRENGTHENING THEREAFTER. 
 
EARL CONTINUES TO MOVE ON A CONSISTENT WESTWARD PATH AND THE INITIAL
MOTION ESTIMATE IS 275/15. A GENERAL WESTWARD MOTION IS FORECAST TO
CONTINUE OVER THE NEXT COUPLE OF DAYS AS THE CYCLONE REMAINS
STEERED BY A NARROW MID-LEVEL RIDGE CENTERED ALONG 25N. EARL IS
EXPECTED TO APPROACH A BREAK IN THE RIDGE...WHICH WILL BE ENHANCED
BY HURRICANE DANIELLE...IN ABOUT 3 DAYS AND THAT SHOULD INDUCE A
TURN TO THE WEST-NORTHWEST TO NORTHWEST WITH A DECREASE IN FORWARD
SPEED. THE TRACK MODEL GUIDANCE REMAINS TIGHTLY CLUSTERED FOR MUCH
OF THE PERIOD AND THE NHC OFFICIAL TRACK FORECAST IS ESSENTIALLY
AN UPDATE OF THE PREVIOUS ONE.
