TROPICAL STORM MARCO DISCUSSION NUMBER   5
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   AL132008
1100 AM EDT TUE OCT 07 2008

HIGH-RESOLUTION VISIBLE SATELLITE IMAGERY INDICATES THAT MARCO HAS 
MADE LANDFALL AND THE CENTER IS JUST INLAND OF THE COAST OF CENTRAL
MEXICO.  THE MOTION HAS BEEN AROUND 270/6 OVER THE PAST FEW
HOURS...AND A GENERAL WESTWARD TO WEST-NORTHWESTWARD HEADING IS
EXPECTED TO CONTINUE TODAY AND TONIGHT.  SINCE THE MOUNTAINS OVER
CENTRAL MEXICO ARE QUITE HIGH...RAPID WEAKENING IS EXPECTED.  A 24
HOUR FORECAST POSITION IS SHOWN BUT IT IS DOUBTFUL THAT A
WELL-DEFINED SURFACE CIRCULATION WILL LAST THAT LONG.  IN
FACT...MARCO COULD DISSIPATE TONIGHT OR VERY EARLY WEDNESDAY. 
STILL...THE REMNANTS OF MARCO COULD PRODUCE VERY HEAVY RAINS OVER
EASTERN PORTIONS OF CENTRAL MEXICO DURING THE NEXT DAY OR SO.
