A 0024Z WINDSAT MICROWAVE OVERPASS REVEALED A DEVELOPING BANDING EYE
FEATURE...AND THAT LANE HAS BEEN MOVING MORE NORTHWESTWARD DURING
THE PAST 6 HOURS.  DVORAK INTENSITY ESTIMATES FROM TAFB AND SAB
REMAIN AT 55 AND 45 KT...RESPECTIVELY...AND THE ADVISORY INTENSITY
IS SET AT 50 KT.  THE INTENSITY FORECAST PHILOSOPHY REMAINS
UNCHANGED FROM THE PREVIOUS PACKAGE...AND FOLLOWS CLOSELY TO THE
SHIPS...WHICH DOES NOT WEAKEN LANE AS RAPIDLY AS THE FSU
SUPERENSEMBLE INDICATES.  CONDITIONS REMAIN RIPE FOR RAPID
STRENGTHENING OVER THE NEXT 24 HOURS...IF LAND INTERACTION DOES NOT
OCCUR.
 
THE INITIAL MOTION IS ESTIMATED AT 305/5...JUST TO THE RIGHT OF THE
PREVIOUS FORECAST...AND A BIT SLOWER.  THE TROPICAL CYCLONE IS
MOVING WITHIN THE SOUTHWEST PERIPHERY OF A LOW- TO MID-LEVEL RIDGE
OVER WEST-CENTRAL MEXICO. A LARGE AMPLITUDE MID-LATITUDE TROUGH IS
DIGGING INTO THE SOUTHWESTERN UNITED STATES...WHICH SHOULD
REINFORCE A WEAKNESS IN THE SUBTROPICAL RIDGE THAT WILL TURN LANE
MORE NORTHWARD...AROUND MID PERIOD.  THE GFDL CONTINUES TO INDICATE
AN ABRUPT NORTHWARD MOTION AND A LANDFALL IN THE HURRICANE WATCH
AREA BETWEEN MANZANILLO AND CABO CORRIENTES.  THE OFFICIAL FORECAST
TRACK HAS AGAIN BEEN ADJUSTED SLIGHTLY EASTWARD OF THE PREVIOUS
ADVISORY...ABOUT HALFWAY BETWEEN THE PREVIOUS TRACK AND THE CURRENT
MODEL CONSENSUS.
