Buoy 42001 seems to be pretty much in the forecast path of Rita, due for
a direct hit in a few hours.

Combined plot is very dramatic!

Wonder if it will auto scale? The pressure is about to fall off the
bottom and the wind gust out of the top...

I imagine it would given it is in prime hurricane territory.
What are the saying about Rita now, sustained winds of 175mph
and gusting higher? Gordon bleedin' Bennett, no wonder they
are saying this is one of the most powerful hurricanes ever recorded.

Yup, it's rescaled. Gusts now heading towards 80 kts, pressure falling
ever more precipitously.
What kind of windspeeds can these buoys record/survive?

Well buoy 42001 has reached 90mph winds, 110mph gusts and 962mbar
pressure, and its still getting worse ....

If you notice there is a lull in wind speed and gusts from 12:00 to
18:00 on the 20th. Truly the lull before the storm.. And a spike in the
pressure plot corresponds to the lull. Although even this shows a brief
pause in it's decent.

Then the graph starts to show the effects of Rita. I'm impressed by how
early the effects show up. Seems a long way out from the actual physical
presence of the system. 18:00 on the 20th and the plots start to
plummet/soar.

A fascinating set of data!

The eye is past: lowest pressure recorded was 925.7, highest recorded
sustained windspeed was only 90mph but with gusts of 120mph. From the
wind directions, I'm not sure if that was a graze by the southern edge
of the eye or a very near miss. It wasn't the faster northern edge of
the eyewall.

If you think about it the anemometer spent much of its time either at a
considerable angle from the horizontal climbing up or sliding down the
40 foot waves, or at the bottom of a 40 foot deep trough (itself being
only 30 feet above sea level). Also, the "air" at this level would
probably be so full of flying spray that it would have the consistency
of shaving foam. So not too accurate I guess.

Anyone have any reasons as to why the wave height was at its lowest during
lowest pressure and highest wind recording ?

"Station 42001 went adrift on 09/23/2005 and the last report from its
moored position (listed above) was at 0230 GMT. It is still
transmitting valid observation data, which continue to be reported
here, but with only this daily update of its location. The 1342 GMT
position on 09/23/2005, is 25°55'13"N 89°38'55"W."


I wonder why...

Those plots are quite stunning.
