HURRICANE IVO DISCUSSION NUMBER 7
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL EP122007
800 PM PDT WED SEP 19 2007
SATELLITE PRESENTATION HAS CONTINUED TO IMPROVE WITH AN AREA OF DEEP
CONVECTION NEAR THE CENTER AND A WELL ESTABLISHED UPPER-LEVEL
OUTFLOW. DVORAK T-NUMBERS FROM BOTH TAFB AND SAB HAVE INCREASED TO
4.0 AND A RECENT MICROWAVE PASSAGE SHOWS A WELL DEFINED RING OF
CONVECTION RESEMBLING AN EYEWALL. ON THIS BASIS...IVO HAS BEEN
UPGRADED TO A 65 KNOT HURRICANE. THERE IS A CHANCE FOR IVO TO
STRENGTHEN SOME DURING THE NEXT 24 TO 36 HOURS. THEREAFTER...A
GRADUAL WEAKENING IS FORECAST SINCE THE SHEAR IS EXPECTED TO
INCREASE...AS INDICATED BY THE SHIPS MODELS. IN FACT...SOME OF THE
GLOBAL MODELS WEAKEN OR LOSE THE CYCLONE BEYOND DAY 3. ONLY THE
GFDL KEEPS IVO AS A HURRICANE ALL THE WAY THROUGH THE COAST OF
MAINLAND MEXICO. WE WILL CONTINUE TO CLOSELY MONITOR FUTURE GFDL
RUNS.
IVO APPEARS TO BE MOVING TOWARD THE NORTHWEST OR 315 DEGREES AT 8
KNOTS AROUND THE SOUTHWESTERN PERIPHERY OF A SUBTROPICAL RIDGE.
THIS RIDGE WILL BE ERODED BY THE DEVELOPMENT OF A LARGE
MID-LATITUDE TROUGH...RESULTING IN VERY WEAK STEERING CURRENTS. IVO
IS EXPECTED TO TURN NORTHWARD VERY SLOWLY AND THEN TURN MORE TO THE
NORTH-NORTHEAST WITHIN THE LIGHT FLOW TO THE SOUTHEAST OF THE
MID-LATITUDE TROUGH. THE TRACK FORECAST BASICALLY FOLLOW THE
SOLUTION OF THE GLOBAL MODELS WITH THE EXCEPTION OF THE GFS
FORECAST WHICH APPEARS TO BE TOO FAR TO THE WEST.
INTERESTS IN SOUTHERN BAJA CALIFORNIA SHOULD CLOSELY MONITOR THE
PROGRESS OF IVO DURING THE NEXT FEW DAYS.

TROPICAL STORM IVO DISCUSSION NUMBER 15
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL EP122007
800 PM PDT FRI SEP 21 2007
THE CONVECTIVE PATTERN ASSOCIATED WITH IVO HAS RAPIDLY DETERIORATED
OVER THE PAST SEVERAL HOURS WITH THE FORMATION OF A SHARP WESTERN
EDGE AND WARMING CLOUD TOP TEMPERATURES...LIKELY DUE TO INCREASING
SOUTHWESTERLY SHEAR. A FORTUITOUS 0028 UTC SSM/I PASS INDICATED
THAT THE LOW-LEVEL CENTER IS LOCATED WELL TO THE SOUTHWEST OF THE
DEEPEST CONVECTION AND THE INITIAL INTENSITY IS SET AT 55 KT IN
ACCORDANCE WITH A DROP IN T-NUMBERS...BUT THIS ESTIMATE IS PROBABLY
GENEROUS.
IVO IS STILL MOVING RATHER SLOWLY BUT THE SSM/I PASS SUGGESTS THAT
THE SYSTEM HAS TAKEN A SLIGHT TURN TO THE RIGHT OF THE EXTRAPOLATED
TRACK...WITH AN INITIAL MOTION OF 030/5. MODEL GUIDANCE REMAINS
SPLIT IN TWO CAMPS REGARDING THE FORECAST TRACK OF IVO. THE UKMET
AND NOGAPS MODELS REMAIN THE NORTHERN OUTLIERS BY MOVING A DEEP
TROPICAL SYSTEM ACROSS THE SOUTHERN PART OF BAJA CALIFORNIA IN
ABOUT 36-48 HOURS. HOWEVER...CONSIDERING THAT VERTICAL SHEAR HAS
ALREADY BECOME A MAJOR FACTOR IN THE WEAKENING OF IVO...THE
GUIDANCE PROVIDED BY THE GFS...ECMWF...AND GFDL MODELS APPEAR MORE
REASONABLE AT THIS TIME. THESE MODELS MOVE THE SHEARED MID-LEVEL
CIRCULATION OF IVO TO THE NORTHEAST ACROSS BAJA WITH THE LOW-LEVEL
CIRCULATION TURNING EAST AND STAYING SOUTH OF BAJA...POSSIBLY
DISSIPATING IN 3-4 DAYS. THEREFORE...THE OFFICIAL FORECAST IS
ADJUSTED TOWARD THE SOUTHERN CLUSTER OF MODELS AND SHOWS VERY SLOW
MOTION AT DAYS 4 AND 5.
THE INTENSITY FORECAST SHOWS A GRADUAL WEAKENING THROUGH THE
FORECAST PERIOD BUT IS NOT AS FAST AS SHIPS GUIDANCE...JUST IN CASE
THE SYSTEM CONTINUES TO GENERATE CONVECTION AS IT MOVES TOWARDS
BAJA. IF THE SHEAR REALLY IS MAKING A KNOCK-OUT PUNCH...WHICH
APPEARS POSSIBLE GIVEN THE SATELLITE REPRESENTATION...THEN IVO
WOULD WEAKEN FASTER THAN INDICATED IN THE OFFICIAL FORECAST.
ALTHOUGH IVO IS EXPECTED TO WEAKEN AS IT APPROACHES SOUTHERN BAJA
CALIFORNIA...TROPICAL STORM WATCHES MAY BE REQUIRED TOMORROW.
