County’s ALERT Weather Telemetry Celebrates 30 Years of Providing Early Warning Systems
SANTA ANA, CA– OC Public Works’ OC Watersheds Division maintains and monitors the County’s early warning system as a flooding prevention and emergency response tool. The ALERT System – so called for Automated Local Evaluation in Real Time -- first implemented in 1983 has helped the County predict future rainfall totals, track storm watches and warnings, and monitor weather radar through the internet, intranet and email.
The County began installation of the ALERT weather telemetry system to support storm operations 30 years ago. Initially consisting of only rain gauges, the system now comprises 130 sensors at over 80 sites that measure precipitation, water level in flood channels, temperature, barometric pressure, wind velocity and direction, relative humidity, and snow. County of Orange personnel and the public can depend on the ALERT system for real-time weather data and with this information, the County can take the appropriate actions, including evacuations, road closures, and flood channel maintenance.
This system received an award of recognition by the National Association of Counties’ “County Achievement Award” in the past for its “Flash Flood Program, Early Warning System,” Not many Counties provide this service and the award was received for Orange County’s innovation.
The ALERT System enables the OC Watersheds Division to provide 24-hour weather forecast information and weather condition interpretation to OC Public Works management, staff, and the public through internet links at: www.ocwatersheds.com/rainrecords/dataresources/rainfalldata/. Data is displayed in tabular and map form updated every eight minutes during rain storms.
