REMNANTS OF GABRIELLE DISCUSSION NUMBER 6 NWS NATIONAL HURRICANE CENTER MIAMI FL AL072013 1100 PM AST THU SEP 05 2013 SATELLITE IMAGERY AND SURFACE OBSERVATIONS INDICATE THAT THE SMALL CIRCULATION OF GABRIELLE HAS DISSIPATED AS IT INTERACTED WITH THE LANDMASS OF HISPANIOLA. SURFACE OBSERVATIONS SUGGEST THAT A BROAD CYCLONIC CIRCULATION REMAINS SITUATED BETWEEN PUERTO RICO AND HISPANIOLA...HOWEVER THE REMAINING DEEP CONVECTION IS LOCATED WELL TO THE EAST...OVER AND SOUTH OF PUERTO RICO AND THE U.S. VIRGIN ISLANDS. GLOBAL MODELS SHOW THE REMNANTS OF GABRIELLE MOVING GENERALLY NORTH-NORTHWESTWARD AND NORTHWARD DURING THE NEXT FEW DAYS AND INTERACTING WITH OR POSSIBLY MERGING WITH THE LARGE AREA OF DISTURBED WEATHER CURRENTLY LOCATED TO THE NORTHEAST OF THE GREATER ANTILLES. BY LATE IN THE WEEKEND OR EARLY NEXT WEEK THE GLOBAL MODELS INDICATE THE DEVELOPMENT OF A LOW PRESSURE AREA SOUTH OR SOUTHWEST OF BERMUDA AHEAD OF A MID/UPPER-LEVEL TROUGH...POSSIBLY ASSOCIATED WITH THE REMNANTS OF GABRIELLE. WHILE THE DETAILS OF THE FORMATION OF THIS LOW ARE UNCLEAR AT THIS TIME...THE REMNANTS OF GABRIELLE WILL BE MONITORED FOR SIGNS OF REGENERATION. ADDITIONAL INFORMATION ON THE REMNANTS OF GABRIELLE CAN BE FOUND IN HIGH SEAS FORECASTS ISSUED BY THE NATIONAL WEATHER SERVICE...UNDER AWIPS HEADER NFDHSFAT1 AND WMO HEADER FZNT01 KWBC. HEAVY RAINFALL WILL REMAIN A THREAT FROM THE REMNANTS OF GABRIELLE FOR THE NEXT COUPLE OF DAYS...AND USERS SHOULD REFER TO PRODUCTS FROM THE NWS WEATHER FORECAST OFFICE IN SAN JUAN FOR MORE INFORMATION ON THAT HAZARD. FORECAST POSITIONS AND MAX WINDS INIT 06/0300Z 19.0N 68.5W 25 KT 30 MPH 12H 06/1200Z...DISSIPATED $$ FORECASTER BRENNAN -------------------------------- I thought I would add this here: NOAA will be deploying its fleet Friday to St. Croix in the U.S. Virgin Islands. Kermit, Miss Piggy and Gonzo are all headed down there. Kermit is scheduled to drop 20 AXBTs on the way. (they measure water temperature at the surface and down into the water column to get a profile of the water temperature at various depths) From the NHC plan of the day: "NOAA WILL DEPLOY EITHER ONE OR 3 AIRCRAFT TO ST CROIX FRIDAY FOR RESEARCH MISSIONS THIS WEEKEND" A hurricane hunter sent me an email this evening saying all three would be going. The latest AXBT message can be downloaded here under a new header this year: ftp://tgftp.nws.noaa.gov/data/raw/so/sofx01.kwbc..txt Temporarily, my site has a live archive with raw AXBT data. It updates hourly here: http://tropicalatlantic.com/noaa-aoc/images.shtml?path=AXBT And can be manually decoded here: http://tropicalatlantic.com/recon/manual/ It does not appear in my live system or in Google Earth. Sometime in 2014 it will. |
