TD 17 was upgraded overnight to Tropical Storm Paloma. More to follow... ...THE DEPRESSION IS UPGRADED TO TROPICAL STORM PALOMA WITH 35-KT WINDS. IT SHOULD BE NOTED THAT THE SFMR ESTIMATED SURFACE WINDS IN EXCESS OF 50 KT IN THE NORTHWEST QUADRANT. HOWEVER... THESE WINDS APPEAR SUSPECT DUE TO HEAVY RAIN AND SHOALING ISSUES. ...THE RAPID INTENSIFICATION INDEX ATTACHED TO THE SHIPS MODEL SHOWS A 50 PERCENT CHANCE OF 30 KT INTENSIFICATION DURING THE NEXT 24 HR. THE HWRF FORECASTS A PEAK INTENSITY 114 KT AND 921 MB IN 72 HR...WHILE THE GFDL FORECASTS A PEAK INTENSITY OF 97 KT AND 961 MB IN 66 HR. THE INTENSITY FORECASTS IS A LITTLE MORE CONSERVATIVE...CALLING FOR A PEAK INTENSITY OF 90 KT IN 72 HR IN BEST AGREEMENT WITH THE ICON CONSENSUS MODEL. THE GUIDANCE MODELS SUGGEST TWO TRACK FORECAST SCENARIOS. FIRST...THE GFDL...HWRF... AND BAMD FORECAST A VERTICALLY DEEP HURRICANE TO MOVE QUICKLY NORTHEAST ACROSS CUBA AND THE BAHAMAS INTO THE ATLANTIC. ON THE OTHER HAND...THE GFS... NOGAPS...UKMET...ECMWF...AND CANADIAN MODELS ALL SHOW PALOMA SHEARING APART AFTER 72 HR AS IT MOVES NORTHEASTWARD... WITH THE REMNANT LOW-LEVEL CIRCULATION TURNING WESTWARD OR NORTHWESTWARD ON THE SOUTH SIDE OF A LOW-LEVEL RIDGE. THE NOGAPS SHOWS THE MOST WESTWARD TRACK...KEEPING PALOMA WEST OF THE CAYMAN ISLANDS. THE GFS IS THE EASTERNMOST OF THIS SET OF SOLUTIONS... SHOWING THE CENTER REACHING THE BAHAMAS. SINCE THE INTENSITY FORECAST IS FOR A STRONG AND VERTICALLY DEEP HURRICANE AT 72 HR... THE TRACK FORECAST LEANS TOWARD THE GFDL/HWRF/BAMD SCENARIO. HOWEVER...THE FORECAST FORWARD SPEED AFTER 72 HR WILL BE SLOWER THAN WHAT THOSE MODELS ARE FORECASTING. http://www.nhc.noaa.gov/text/refresh/MIATCDAT2+shtml/060858.shtml |
