    That's a really cool program. I mean, that chances of max winds being sampled by an ASOS site are pretty slim owing to the paucity of the ASOS network. It's cool to see mobile towers being erected to better fill the gaps in the ASOS/AWOS network. Their blog/update is also pretty interesting.

    Although not the tower data written about earlier... I've added the NOS-PORTS data to my sfc plot for landfall area. Map updates three times per hr.

    This is kind of a NOW ob, but oh well...

    Site T5 should be very near the eye per radar. Current pressure reading is 946.9mb, with 3-sec winds of 101mph and 0.1s gust of 115mph.

    Pressure at T3 and T5 continue to drop, now into the low 940s. The 0.1-1s gusts are generally in the 110-115mph range, with 3s winds of 108mph at T5. I believe NHC considers "sustained winds" to be the average wind over a 10s period. However, the FCMP doesn't report 10s winds, only 3s and 60s surrounding the 10s.

    Anyone take notice of T0's 0.1 second wind gust to 240 mph, also a 3.0 second gust of 185! Whats with that? Are they generally accurate?

    Note: Hurricane Rita September 23, 2005 11:26PM EDT

    FCMP mobile tower T0 Wind (Vane) Monitor is reporting wrong wind speeds,
    please do not consider these values, only refer to the 10 and 5 meter Gill
    Anemometers.
