San Bernardino residents near the county line are on alert after the Summit Fire exploded in size Sunday, prompting evacuation warnings for parts of Piñon Hills and Wrightwood and the movement of local firefighting resources to the front lines.
What changed for residents
San Bernardino County officials issued evacuation warnings for zones PIN005, PIN006 and WWD03, urging those who need extra time to evacuate — including people with pets or livestock — to leave now. County officials said no mandatory evacuation orders had been issued in San Bernardino County at the time of the latest update, though orders remain in effect across the border in Los Angeles County.
Fire growth, mapping and sheltering
Incident briefings showed rapid growth during the afternoon and evening. An intelligence aircraft later mapped the fire at 2,676.9 acres, a significant increase from earlier estimates. Fire agencies said the blaze is wind driven and continues to threaten structures near Highway 138 and Jesus Canyon Road.
- Early afternoon estimate: around 620 acres
- Mid-afternoon mapping: around 805.9 acres
- Later afternoon/early evening: 1,300 to 2,271 acres reported
- Night mapping by aircraft: 2,676.9 acres
"There are currently no evacuation warnings or evacuation orders in effect for San Bernardino County residents,"
That advisory language has shifted as officials expanded warnings into more areas. Los Angeles County authorities have opened shelters for displaced residents; the Antelope Valley Family YMCA in Lancaster was listed as a public shelter, and animal care facilities were activated in Palmdale for small animals.
San Bernardino response and what officials deployed
San Bernardino County Fire dispatched two strike teams, a dozer and overhead personnel to the Piñon Hills vicinity to provide structure defense as the Summit Fire burned across the Los Angeles County line. The county also urged residents to heed warnings and prepare to evacuate if conditions worsen.
