San Diego County published an announcement on Sep. 23, 2026; the County says the Weather Center in Kearny Mesa supports field operations and enhances public safety.

The County identified the Flood Control District as the center’s operator and said the center manages the Automatic Local Evaluation in Real‑Time (ALERT) system; the County described ALERT as the county’s flood‑warning network that collects and analyzes data from rain and stream gauges.

According to the County, ALERT sensors track rainfall, river levels and streamflow and issue early warnings to downstream communities when levels signal possible flooding; the County says real‑time data also guides planning decisions and directs field operations.

The County says road crews rely on ALERT updates to respond to flooding, close roads and take steps to protect the public; the County further stated the Weather Center’s work helps reduce flood risk across the region.
