800 AM PDT SAT MAY 19 2012
 
ALTHOUGH A FEW SHOWERS ARE LINGERING ABOUT 60 TO 90 N MI TO THE
NORTH OF THE CENTER OF ALETTA...THIS CONVECTIVE ACTIVITY IS NOT
ENOUGH TO MAINTAIN THE SYSTEM AS A TROPICAL CYCLONE. IN FACT...
ALETTA HAS BEEN DEVOID OF ORGANIZED DEEP CONVECTION FOR AT LEAST 12
HOURS. THEREFORE...THE CYCLONE IS NOW A POST-TROPICAL REMNANT LOW
AND THIS IS THE LAST ADVISORY ON THIS SYSTEM. FOR FUTURE
INFORMATION ON THE REMNANTS OF ALETTA PLEASE SEE HIGH SEAS
FORECASTS ISSUED BY THE NATIONAL WEATHER SERVICE...UNDER AWIPS
HEADER NFDHSFEPI AND WMO HEADER FZPN01 KWBC. 

THE POST-TROPICAL CYCLONE IS MOVING EAST-NORTHWARD AT ABOUT 4 KT. A
GRADUAL TURN TO THE SOUTH IS FORECAST TO OCCUR LATER TODAY...AND
THE REMNANT LOW IS EXPECTED TO CONTINUE MOVING IN THAT GENERAL
DIRECTION UNTIL IT DISSIPATES IN ABOUT 48 HOURS.
