Rainfall and Weather Data

Hackberry-BigBug2022.jpg ALERT is an acronym for “Automated Local Evaluation in Real Time” and refers to a National Weather Service format developed in the 1970s for transmission of hydrometeorological data from remote sensors via radio in real-time. The Yavapai County Flood Control District ALERT System consists of precipitation gauges, stream gauges and other weather-related sensors that have been strategically placed in watersheds impacting communities in Yavapai County. Sensors transmit data from remote sites using VHF radio via mountain top repeaters to our base station in Prescott where it is received, decoded, time stamped and stored on our base station computer for analysis. A separate database is networked to our base station allowing data to be viewed on the web.

ALERT data is received on a real-time basis from remote sensors and displayed as general information, only. All data should be treated as preliminary, therefore subject to revision. While every attempt is made to assure gauges report accurate data, there are occasionally times when outside factors affect data quality (i.e. vandalism, equipment malfunctions, routine maintenance and testing, insects, data collision, gauge placement, wind, snow, hail, etc.). In addition, network outages break the link to timely data reports. As a result, it is crucial the user pay attention to the date and time of the data. The Yavapai County Flood Control District makes no warranty, expressed or implied, regarding the accuracy of the data located on this server.
