Just The Facts On Hurricane Ike-Tropical Storm Hanna Radar Loop



Hurricane Ike Satellite 1845Z 0906

Had to get a birthday present for Snow White.  So, its just graphics and discussion. Will add my two cents this evening.  Here is a link to Tropical Storm Hanna Radar Loop. Click Here and navigate from the default area of the Ohio Valley to wherever you like, down to street level.  Add lightning and clouds if you like. Hit “animate” to loop the image.

IKE CONTINUES TO EXPERIENCE SOME NORTHEASTERLY SHEAR AND LATEST

DVORAK INTENSITY ESTIMATES NOW SUGGEST ABOUT 95 KT.  GLOBAL MODELS
INDICATE THAT THE NORTHEASTERLY SHEAR WILL BEGIN TO RELAX LATER
TODAY…AND IKE IS NOW FORECAST TO TRACK SOUTH OF THE COOLER WATERS
UPWELLED BY HANNA.  SOME RESTRENGTHENING IS ANTICIPATED IN THE
SHORT-TERM AND IKE COULD REGAIN MAJOR HURRICANE STATUS BY TOMORROW.

IKE IS THEN EXPECTED TO MOVE OVER OR VERY CUBA DURING THE 36-72 HR
TIME FRAME WHICH SHOULD RESULT IN SOME WEAKENING.  THE DEGREE OF
WEAKENING WILL DEPEND LARGELY ON HOW CLOSE IKE TRACKS TO LAND.  BY
DAY 4…IKE IS FORECAST TO EMERGE BACK OVER OPEN WATERS IN THE
SOUTHEASTERN GULF OF MEXICO.  GLOBAL MODELS SUGGEST THE ENVIRONMENT
WILL BE FAVORABLE FOR STRENGTHENING AND THE OCEAN SHOULD BE PLENTY
WARM.  THE OFFICIAL FORECAST THUS CALLS FOR IKE TO RESTRENGTHEN AT
96 AND 120 HR.  GIVEN THE EVOLVING ATMOSPHERIC ENVIRONMENT AND LAND
INTERACTIONS…THE INTENSITY FORECAST HAS LOWER THAN NORMAL
CONFIDENCE.

IKE IS CURRENTLY BEING STEERED BY A LARGE MIDDLE TO UPPER-LEVEL
RIDGE OVER THE WESTERN ATLANTIC NEAR BERMUDA AND THE CYCLONE
CONTINUES ON A GENERAL WEST-SOUTHWESTWARD HEADING WITH AN INITIAL
MOTION ESTIMATE OF 255/15. THE RIDGE IS FORECAST TO SHIFT EASTWARD
DURING THE NEXT COUPLE OF DAYS ALLOWING IKE TO MAKE A TURN
WESTWARD. IN 3 TO 4 DAYS…A SHORTWAVE TROUGH MOVING OVER THE
EASTERN UNITED STATES IS EXPECTED TO CREATE A WEAKNESS TO THE NORTH
OF IKE RESULTING A TURN TOWARD THE WEST-NORTHWEST OR NORTHWEST.
THIS SHORTWAVE TROUGH WILL BE A CRITICAL PLAYER IN IKE’S EVENTUAL
TRACK AT THE EXTENDED RANGES. DYNAMICAL MODELS ARE SPLIT INTO TWO
CAMPS AT THIS TIME…WITH SOME MODELS SHOWING THE SHORTWAVE PASSING
SUFFICIENTLY FAR TO THE NORTH TO KEEP IKE MOVING
WEST-NORTHWESTWARD…WHILE OTHER MODELS SHOW IKE TURNING NORTHWARD
INTO THE WEAKNESS. IT IS WAY TOO EARLY TO COMMIT TO EITHER ONE OF
THESE EXTENDED RANGE SOLUTIONS…AND THUS THE NEW OFFICIAL FORECAST
IS VERY CLOSE TO THE PREVIOUS ADVISORY.
