A site I picked up while in the Navy (stationed in Pascagoula, Mississippi, which is now getting absolutely hammered by Ivan): National Buoy Data Center
. On the map, click Western Gulf, then Louisiana, Mississippia, then Station 42040
(Just off Mobile Bay). At 6:50 pm, it showed a 52 foot wave and 52kt winds. Its interesting to watch these as the hurricane approaches.
Buoy 41009, off Cape Canaveral got ripped off its mooring in the last hurricane. Its been retrieved, but isn't back operating yet.
