KARL MADE LANDFALL JUST NORTH-NORTHWEST OF VERACRUZ MEXICO AT
ABOUT 1630Z.  BEFORE LANDFALL...THE CENTRAL PRESSURE RAPIDLY ROSE
FROM 957 MB TO 976 MB OVER A 4.5 HOUR PERIOD FOR REASONS THAT ARE
NOT READILY APPARENT.  DESPITE THIS...THE AIRCRAFT-REPORTED WINDS
SUPPORTED MAJOR HURRICANE INTENSITY UNTIL LANDFALL.  SINCE LANDFALL
THE HURRICANE HAS STEADILY WEAKENED...AND THE INITIAL INTENSITY OF
80 KT MAY BE A BIT GENEROUS.  KARL SHOULD CONTINUE TO WEAKEN AS IT
MOVES OVER THE MOUNTAINS OF MEXICO...AND THE CYCLONE IS LIKELY TO
DISSIPATE COMPLETELY BY 48 HR.
 
THE INITIAL MOTION IS 250/8.  A MID-LEVEL RIDGE OVER NORTHERN MEXICO
SHOULD CONTINUE TO STEER KARL TOWARD THE WEST-SOUTHWEST OR WEST
UNTIL DISSIPATION.
