Incident Update Lake Fire

Situation Summary

As of Saturday evening, the Lake Fire continues to burn actively in the Silverwood Lake area north of Hesperia, prompting mandatory evacuations south of Highway 138 between Interstate 15 and Highway 173. Firefighters are engaged in aggressive suppression efforts, supported by multiple aircraft and ground resources. Due to increased fire behavior and visibility concerns, portions of I-15 remain impacted. Crews will continue working overnight to build containment lines and address hotspots along the active flanks of the fire.

Weather conditions are playing a significant role in fire activity. This evening, gusty south winds ranging from 15 to 25 mph are expected to persist before gradually weakening after 10:00 p.m. Relative humidity will rise from around 20% to near 45% overnight, helping moderate fire behavior. However, conditions will dry out again on Sunday with humidity dropping back to 20% and winds gusting up to 25 mph in the afternoon. Monday is forecast to bring stronger wind gusts exceeding 30 mph, which could challenge suppression efforts. Fire personnel remain vigilant in monitoring the weather to adapt operational strategies accordingly. A morning update will include refined acreage and containment figures.
