500 PM AST SUN AUG 18 2013
 
ERIN HAS LACKED DEEP CONVECTION WITHIN 120 N MI OF ITS CENTER FOR
OVER 12 HOURS...AND NO LONGER QUALIFIES AS A TROPICAL CYCLONE.
THEREFORE...ADVISORIES ARE BEING DISCONTINUED AT THIS TIME.  THE
SHIPS/LGEM GUIDANCE INDICATES VERY DRY LOW- TO MID-TROPOSPHERIC AIR
IN THE PATH OF THE REMNANT LOW WHICH SHOULD DISCOURAGE ATTEMPTS AT
REGENERATION.
 
THE LOW HAS BEEN MOVING SLIGHTLY SOUTH OF WEST...OR 260/7...WITHIN
THE TRADEWIND FLOW.  THIS GENERAL MOTION IS EXPECTED TO CONTINUE
UNTIL THE CYCLONE LOSES ITS IDENTITY IN A FEW DAYS.  THE OFFICIAL
TRACK FORECAST IS A LITTLE SOUTH OF THE PREVIOUS ONE AND NEAR THE
NORTHERN SIDE OF THE DYNAMICAL GUIDANCE SUITE.
 
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.
