Tropical Depression IGNACIO


ZCZC MIATCDEP2 ALL
TTAA00 KNHC DDHHMM
TROPICAL DEPRESSION IGNACIO DISCUSSION NUMBER  12
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP122009
800 AM PDT THU AUG 27 2009
 
IGNACIO HAS BEEN DEVOID OF ORGANIZED DEEP CONVECTION FOR ABOUT 12-18
HOURS. THE CYCLONE CONSISTS OF A LARGE SWIRL OF LOW- TO MID-LEVEL
CLOUDS...SIGNALING THE DEGENERATION OF IGNACIO TO REMNANT LOW
STATUS. THE INITIAL INTENSITY IS KEPT AT 30 KT...OUT OF RESPECT OF
THE OVERNIGHT SCATTEROMETER DATA WHICH SHOWED 30-35 KT WIND
VECTORS. SINCE IGNACIO IS A LARGE CYCLONE...THE WINDS MAY DECREASE
MORE SLOWLY THAN IS TYPICAL FOR A SYSTEM THAT IS SPINNING DOWN OVER
COOL WATER. 

THE INITIAL MOTION IS 320/12. THE REMNANT LOW SHOULD CONTINUE MOVING
NORTHWESTWARD DURING THE NEXT 24 HOURS...THEN GRADUALLY DECELERATE
AND TURN MORE WESTWARD IN THE LOW-LEVEL EASTERLY FLOW.

THIS IS THE LAST NHC ADVISORY ON THIS SYSTEM. FOR ADDITIONAL
INFORMATION ON THE REMNANT LOW PLEASE SEE HIGH SEAS FORECASTS
ISSUED BY THE NATIONAL WEATHER SERVICE...UNDER AWIPS HEADER
NFDHSFEPI AND WMO HEADER FZPN02 KWBC.
