HURRICANE KATRINA SPECIAL DISCUSSION NUMBER 13 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 1130 AM EDT FRI AUG 26 2005
THIS SPECIAL ADVISORY DISCUSSION IS ONLY TO MODIFY THE INITIAL AND FORECAST INTENSITIES. RECENT DROPSONDE DATA FROM AN AIR FORCE RESERVE UNIT RECONNAISSANCE AIRCRAFT MEASURED A SURFACE WIND OF 83 KT IN THE SOUTHEAST EYEWALL. THE MINIMUM PRESSURE OF 971 MB ALSO CORRESPONDS TO ABOUT 88 KT SURFACE WINDS. THEREFORE...THE INITIAL INTENSITY HAS BEEN INCREASED TO 85 KT...OR 100 MPH.
GIVEN THE RAPID IMPROVEMENT IN THE INNER CORE STRUCTURE AND THE SHARP PRESSURE DROP...RAPID INTENSIFICATION SEEMS LIKELY FOR THE NEXT 12 HOURS OR SO. AFTERWARDS...STEADY INTENSIFICATION TO NEAR CATEGORY FOUR STRENGTH BY 72 HOURS APPEARS TO BE IN ORDER GIVEN THE VERY WARM GULF WATERS BENEATH THE HURRICANE AND THE VERTICAL SHEAR FORECAST TO DECREASE TO LESS THAN 10 KT BY 48 HOURS. :shock:
