Post-Tropical Cyclone RINA


ZCZC MIATCDAT3 ALL
TTAA00 KNHC DDHHMM
 
POST-TROPICAL CYCLONE RINA DISCUSSION NUMBER  23
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL182011
400 PM CDT FRI OCT 28 2011

AN ASCAT OVERPASS NEAR 1600 UTC SHOWED THAT THE CIRCULATION OF RINA
HAS BECOME LESS ORGANIZED.  A SMALL AREA OF 25-KT WINDS WAS LOCATED
ABOUT 60 N MI EAST OF THE CENTER...WITH WINDS OF 15 KT OR LESS IN
MUCH OF THE REMAINDER OF THE CIRCULATION.  IN ADDITION...THE
CIRCULATION IS BECOMING EMBEDDED IN A NORTH-SOUTH TROUGH OF LOW
PRESSURE EXTENDING FROM THE EAST CENTRAL GULF OF MEXICO INTO THE
NORTHWESTERN CARIBBEAN.  THERE HAS BEEN NO ORGANIZED CENTRAL
CONVECTION FOR ABOUT 15 HOURS NEAR THE SURFACE CIRCULATION OF RINA. 
BASED ON THIS INFORMATION...RINA HAS DEGENERATED INTO A REMNANT
AREA OF LOW PRESSURE.  REGENERATION IS NOT EXPECTED DUE TO
CONTINUING STRONG VERTICAL WIND SHEAR AND DRY AIR ENTRAINMENT.
 
THE INITIAL MOTION IS NOW 060/4.  THE REMNANTS OF RINA ARE EXPECTED
TO TURN SOUTHEASTWARD AND SOUTHWARD DURING THE NEXT 48 HOURS...
FOLLOWED BY A SOUTH-SOUTHWESTERLY MOTION UNTIL DISSIPATION OCCURS.
 
THIS IS THE LAST ADVISORY ON RINA BY THE NATIONAL HURRICANE CENTER. 
ADDITIONAL INFORMATION ON THIS SYSTEM CAN BE FOUND IN HIGH SEAS
FORECASTS ISSUED BY THE NATIONAL WEATHER SERVICE...UNDER AWIPS 
HEADER NFDHSFAT1 AND WMO HEADER FZNT01 KWBC.
