there's a post by a biologist that lives/works at that station on another board, here's a part:
The met station is part of a system installed in federal protected lands by CONAGUA and CONANP, the government agencies in charge of the national meteorological system and the national protected areas systems, respectively. The biology station is located at the top of a hill, at an altitude of around 95 meters asl, and the anemometer is approximately 9.7 m above ground. The station was situated, as some of you have stated, on the NW quadrant of Patricia at landfall. The anemometer in question is a RM Young ultrasonic sensor (SDI-UWS-RMY), and I did suspected its readings since Patricia. Before the hurricane, the station had been giving reliable information, but at some point during the storm the sensor got tilted considerably (I thought it would not survive). I attach a picture of it. Besides that, the range of operation goes from 0 to 70 m/s, so anything above 252 km/h cannot be sensed by this thing. I downloaded the data as soon as I got to the station on the 24th, and I also noticed the red flags. I think the crazy readings (in the thousands of kph) might just be malfunctioning, and I agree that the very high winds sustained for an inordinate amount of time look really bad. All data from 18:20 to 19:40 might be garbage, and of course the anemometer remained tilted, so any data since 18:20 are affected. The pressure readings I believe.
