San Diego Weather

Many firefighters have been entrapped due to rapid changes in weather causing unexpected fire behavior. These weather events are often predictable using local weather measurements and forecasts, but on-the-ground firefighters have historically lacked access to this information. The Fire Weather Alert System provides this access. It monitors nearby weather observations and forecasts to warn firefighters of dangerous incoming weather and provides convenient map-based access to fire-specific weather information (RAWS, NWS zone fire weather forecasts, NEXRAD radar data, etc.).
