Multiple wildfires occurred in Southern California due to powerful Santa Ana winds and dry vegetation, resulting in extensive destruction and evacuations.
Three major fires are under investigation by Cal Fire as they impact regions west of LA and in the San Gabriel Mountains.
The Santa Ana winds significantly contribute to fire development by drying out vegetation and carrying embers across long distances.
Steep slopes and mountainous terrains contribute to accelerated fire spread, exacerbating conditions in more fire-prone areas.
Urban expansion in these areas has created wildland-urban interfaces, increasing the risk of fire damage in sought-after neighborhoods.
