  Any and all comments are welcomed… Thanks to all who visit this blog... ------------------------------------------------------ THE PARADE HAS BEGUN  ------------------------------------------------------- BULLETIN TROPICAL DEPRESSION INGRID ADVISORY NUMBER 19 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL082007 1100 PM AST SUN SEP 16 2007 ...INGRID WEAKENS JUST EAST OF THE NORTHERN LEEWARD ISLANDS... INTERESTS IN THE NORTHERN LEEWARD ISLANDS SHOULD MONITOR THE PROGRESS OF INGRID. FOR STORM INFORMATION SPECIFIC TO YOUR AREA...INCLUDING POSSIBLE INLAND WATCHES AND WARNINGS...PLEASE MONITOR PRODUCTS ISSUED BY YOUR LOCAL WEATHER OFFICE. AT 1100 PM AST...0300Z...THE CENTER OF TROPICAL DEPRESSION INGRID WAS LOCATED NEAR LATITUDE 17.4 NORTH...LONGITUDE 59.4 WEST OR ABOUT 160 MILES...255 KM...EAST OF THE LEEWARD ISLANDS. THE DEPRESSION IS MOVING TOWARD THE WEST NEAR 9 MPH...AND A MOTION TOWARD THE WEST OR WEST-NORTHWEST IS EXPECTED DURING THE NEXT 24 HOURS. ON THIS TRACK...THE CENTER OF INGRID WILL PASS OVER OR NEAR THE NORTHERN LEEWARD ISLANDS TOMORROW. MAXIMUM SUSTAINED WINDS ARE NEAR 30 MPH...45 KM/HR...WITH HIGHER GUSTS. LITTLE CHANGE IN STRENGTH IS FORECAST DURING THE NEXT 24 HOURS. THE MINIMUM CENTRAL PRESSURE...BASED ON SURFACE OBSERVATIONS AND REPORTS FROM A NOAA HURRICANE HUNTER AIRCRAFT...IS 1010 MB...29.83 INCHES. REPEATING THE 1100 PM AST POSITION...17.4 N...59.4 W. MOVEMENT TOWARD...WEST NEAR 9 MPH. MAXIMUM SUSTAINED WINDS...30 MPH. MINIMUM CENTRAL PRESSURE...1010 MB. THE NEXT ADVISORY WILL BE ISSUED BY THE NATIONAL HURRICANE CENTER AT 500 AM AST. $$ FORECASTER KNABB ------------------------------------------------------- Atlantic Tropical Weather Outlook ------------------------------------------------------- TROPICAL DEPRESSION INGRID DISCUSSION NUMBER 19 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL082007 1100 PM EDT SUN SEP 16 2007 DEEP CONVECTION ESSENTIALLY DISAPPEARED AFTER ABOUT 21Z. ANALYSIS OF THE AMBIGUITIES FROM A 2145Z QUIKSCAT OVERPASS REVEALED WINDS NO STRONGER THAN 25 KT...AND EVEN THOSE WINDS WERE IN AN ISOLATED AREA OF SHOWERS ABOUT 80-90 N MI EAST OF THE CENTER. SHOWER ACTIVITY HAS CONTINUED TO DISSIPATE SINCE THEN...SO THE NEW ADVISORY INTENSITY IS SET TO 25 KT...DESPITE SLIGHTLY HIGHER DVORAK ESTIMATES. ALONG THE FORECAST TRACK...GLOBAL MODEL FIELDS SHOW CONTINUED STRONG WESTERLY SHEAR FOR AT LEAST THE NEXT 48 HOURS. A SMALL WINDOW OF OPPORTUNITY EXISTS FOR INGRID TO STRENGTHEN ON DAYS 3 AND 4 WHEN THE SHEAR DECREASES A LITTLE...BUT THAT IS ASSUMING THE SYSTEM STILL EXISTS AT THAT TIME. THE NEW OFFICIAL INTENSITY FORECAST KEEPS THE CYCLONE AS A 25-KT DEPRESSION THROUGHOUT THE FIVE-DAY PERIOD...AS SUGGESTED BY THE LGEM GUIDANCE...BUT IT MIGHT NOT BE A TROPICAL CYCLONE FOR NEARLY THAT LONG. THE QUIKSCAT DATA SHOWED THAT THE CENTER IS A LITTLE SOUTH OF THE PREVIOUS TRACK...WITH AN INITIAL MOTION ESTIMATE OF 280/8. INGRID CONTINUES TO MOVE LEFT OF MOST OF THE MODEL GUIDANCE SINCE...IT IS SUCH A SHALLOW SYSTEM AND IS MOVING WITH THE LOW-LEVEL EASTERLIES. FOR THE SAME REASON...THE NEW OFFICIAL FORECAST WILL BE LEFT OF MOST OF THE TRACK MODELS AND THE PREVIOUS ADVISORY...ALONG A TRACK THAT IS CLOSEST TO THE GFDL AND SHALLOW BAM. A GRADUAL BEND TO THE RIGHT IS STILL FORECAST SINCE THE LOW-LEVEL RIDGE NORTH OF INGRID IS EXPECTED TO WEAKEN. BY DAYS 4 AND 5...INGRID OR WHATEVER IS LEFT OF IT WILL BE IN A VERY WEAK LOW-LEVEL STEERING REGIME...FAR TO THE SOUTH OF HIGH PRESSURE NEAR THE NORTHEAST U.S. COAST.
