 HURRICANE FELICIA DISCUSSION NUMBER   8
 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP082009
 ISSUED BY THE HYDROMETEOROLOGICAL PREDICTION CENTER CAMP SPRINGS MD
 800 AM PDT WED AUG 05 2009
  
 BASED UPON SATELLITE INTENSITY ESTIMATES AT 1200 UTC FROM TAFB AND
 SAB OF T6.0 AND T5.0...RESPECTIVELY... AND A PERSISTENT EYE WITH
 DEEP CONVECTION LOCATED IN THE EASTERN AND SOUTHEASTERN
 SEMICIRCLES...THE INITIAL INTENSITY IS BEING RAISED TO MAJOR
 HURRICANE STATUS AT 100 KT.
 
 LITTLE CHANGE IS ANTICIPATED TO THE INITIAL HEADING OVER THE NEXT
 COUPLE OF DAYS AS A DEEP MID-LEVEL TROUGH TO ITS NORTH REMAINS IN
 PLACE.  A MORE WESTERLY TRACK IS EXPECTED BY DAYS 3 THROUGH 5 AS
 THIS TROUGH MOVES INLAND ACROSS THE CONTIGUOUS UNITED STATES AND IS
 REPLACED BY A MID-LEVEL HIGH CURRENTLY CENTERED NORTH OF THE
 HAWAIIAN ISLANDS.  UNDER THE INFLUENCE OF COLDER SEA SURFACE
 TEMPERATURES FELICIA WILL LIKELY BE WEAKENING BY THAT POINT AND
 WILL BECOME MORE STRONGLY INFLUENCED BY THE LOWER-LEVEL TRADE
 WINDS.  FOLLOWING THE NORTHWARD SHIFT IN THE GUIDANCE ENVELOPE FOR
 THIS PACKAGE...THE OFFICIAL FORECAST REFLECTS A SLIGHT NORTHWARD
 SHIFT AS WELL.
  
 THE ENVIRONMENT AROUND FELICIA REMAINS CONDUCIVE FOR THE STORM TO
 MAINTAIN ITS CURRENT INTENSITY AT LEAST OVER THE NEXT DAY AS THE
 AFOREMENTIONED MID-LEVEL CUT-OFF LOW NEAR CALIFORNIA IS INDUCING
 DIFFLUENCE ALOFT WHILE VERTICAL SHEAR IS EXPECTED TO REMAIN LIGHT. 
 OCEANIC HEAT CONTENT SHOULD REMAIN SUFFICIENT FOR AT LEAST THE NEXT
 36 HOURS UNTIL THE CONTINUED NORTHWARD SHIFT IN THE TRACK FORECAST
 PUTS FELICIA OVER COOLER WATERS.
