Thread: Tropical Depression Arthur dissapted

OK- we KNOW models don't do well when there is not a well defined and initialized closed center.
Maybe the GFDL lost that . . .

Seriously crazy . . . It's NOT just the GDFL -



They ALL seem to want to keep him alive and turn him right to one extent or another. Guessing that's inresponse to the anticipated weaking of that ridge of high pressure later on . . .

Arthur dissipates over Mexico/Guatemala border

TROPICAL DEPRESSION ARTHUR DISCUSSION NUMBER 7

1100 PM EDT SUN JUN 01 2008

FOR MANY HOURS ARTHUR HAS NOT BEEN PRODUCING SUFFICIENT ORGANIZED
DEEP CONVECTION REQUISITE OF A TROPICAL CYCLONE. IN ADDITION...THE
SURFACE CIRCULATION HAS BEEN ENCOUNTERING MORE RUGGED TERRAIN WHILE
PROCEEDING SLOWLY SOUTHWESTWARD...AND IT HAS BECOME POORLY DEFINED
AND ELONGATED AND MIGHT NOT EVEN BE CLOSED. THEREFORE...THIS WILL
BE THE LAST NHC ADVISORY ON THIS SYSTEM. THIS CHANGE IN STATUS...
HOWEVER...DOES NOT MEAN THAT THE RAINFALL AND FLOODING HAZARD HAS
ENDED. SINCE THE CLOSED CIRCULATION APPEARS TO BE DISSIPATING...NO
FORECAST POINTS ARE PROVIDED...BUT THE REMNANTS ARE EXPECTED TO
CONTINUE MOVING VERY SLOWLY SOUTHWESTWARD DURING THE NEXT COUPLE OF
DAYS. THE REMNANTS OF ARTHUR ARE ALSO EMBEDDED WITHIN A LARGER AND
NEARLY STATIONARY AREA OF LOW- TO MID-LEVEL CYCLONIC FLOW....SO
HEAVY RAINS COULD PERSIST OVER PORTIONS OF SOUTHEASTERN MEXICO AND
NORTHERN CENTRAL AMERICA FOR THE NEXT COUPLE OF DAYS AND PERHAPS
LONGER. FOR INFORMATION SPECIFIC TO YOUR AREA...PLEASE CONSULT
PRODUCTS ISSUED BY YOUR LOCAL WEATHER OFFICE.
