I don't mean to start an argument, but Mitch wasn't a CAT 5 at landfall. When the centre of Mitch moved ashore it was a 50kt tropical storm:-

ZCZC MIATCDAT3 ALL
TTAA00 KNHC DDHHMM
TROPICAL STORM MITCH DISCUSSION NUMBER 33
NATIONAL WEATHER SERVICE MIAMI FL
4 PM EST THU OCT 29 1998

THE HURRICANE HUNTERS AND SATELLITE ANALYSTS INDICATE THAT THE
CENTER OF MITCH IS NOW OVER LAND...HAVING DRIFTED SOUTHWARD TODAY.
HIGHEST 850 MB FLIGHT-LEVEL WINDS WERE 57 KT. STEADY WINDS OF
50 KT WERE REPORTED A FEW HOURS AGO FROM TRUJILLO HONDURAS BY THE
METEOROLOGICAL SERVICE OF HONDURAS. MITCH IS DOWNGRADED TO A
TROPICAL STORM WITH 50 KT WINDS.

Mitch actually lost CAT 5 status about 2 days prior to landfall:-

While Mitch was a CAT 5 at peak intensity (ranked at the 4th most intense hurricane ever observed in the Atlantic basin), it was a shadow of its former self at landfall - the damage was caused by the phenomenal amount of rain it brought with it.
