Tropical Storm ARTHUR (Text)

ZCZC MIATCDAT1 ALL
TTAA00 KNHC DDHHMM
TROPICAL STORM ARTHUR SPECIAL DISCUSSION NUMBER   1
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   AL012008
100 PM EDT SAT MAY 31 2008
 
THE AREA OF LOW PRESSURE LOCATED IN THE NORTHWESTERN CARIBBEAN
BECAME A TROPICAL STORM AS IT WAS CROSSING THE COAST OF BELIZE
EARLY THIS MORNING. THIS IS BASED ON SATELLITE IMAGERY...SHIP DATA
AND A NOAA BUOY 42056 WHICH REPORTED SUSTAINED WINDS OF TROPICAL
STORM FORCE. INITIAL INTENSITY IS SET AT 35 KNOTS BUT BECAUSE
ARTHUR IS ALREADY INLAND..WEAKENING IS ANTICIPATED.  THERE IS A
POSSIBILITY THAT ARTHUR REGAIN TROPICAL STORM STATUS IF IT MOVES
BACK OVER WATER IN THE BAY OF CAMPECHE.

BEST ESTIMATE OF THE INITIAL MOTION IS 290/07. ARTHUR IS ALREADY
SOUTH OF A DEVELOPING RIDGE OVER THE GULF OF MEXICO...THEREFORE A
GENERAL WEST-NORTHWEST TO WEST TRACK IS FORECAST. NONE OF THE
AVAILABLE MODEL GUIDANCE BRINGS ARTHUR NORTHWARD AWAY FROM THE BAY
OF CAMPECHE.    

THIS SYSTEM IS NOT DESIGNATED TROPICAL STORM ALMA BECAUSE THE
SURFACE CENTER OF ALMA DISSIPATED OVER THE HIGH TERRAIN OF CENTRAL
AMERICA YESTERDAY.
