PyroCast turns LA fire weather into a field guide
A local fire-weather publication for Los Angeles and Ventura counties, combining weather checks, reports, explainers, and an interactive fire-spread simulator.
Field notes
PyroCast combines a local fire-weather check with a terrain simulator that models a spark moving through grass, brush, rock, and slopes. Visitors can adjust wind direction, wind speed, and fuel moisture; the example state uses 15 mph wind and 8% fuel moisture. The page also explains why containment figures can mislead, how Santa Ana winds alter fire behavior, and the practical difference between an evacuation warning and an order.
