The San Bernardino National Forest Service announced Sunday that a portion of the Pacific Crest Trail has been closed due to the Lake Fire, which continues to burn near Hesperia. According to officials, the fire is directly impacting the stretch of trail between Silverwood Lake and Interstate 15 along Highway 138. That section is now closed to all foot traffic to ensure public safety.
Meanwhile, Cal Fire reported that forward progress on the blaze has been stopped. In an update issued at 7:30 a.m. Sunday, officials said the wildfire had burned 478 acres and was 10 percent contained. The fire was first reported just before 4 p.m. Saturday near the Silverwood Lake State Recreation Area.
A mandatory evacuation order has been issued for the area south of the 138 Freeway between the 15 and 173 freeways. Portions of the 15, the busiest freeway in the region, will be affected due to fire behavior and visibility concerns, according to officials.
There is also an evacuation warning still in place for the area north of the 138, west of the 173 and east of Summit Valley Road.
“Weather conditions are playing a significant role in fire activity,” Cal Fire said in the Lake Fire situation summary on Saturday night, explaining that the evening’s gusty winds gradually died down as relative humidity rose, which helped to mitigate fire behavior.

The forecast does not indicate that firefighting conditions will be getting better.
“Conditions will dry out again on Sunday with humidity dropping back to 20 percent and winds gusting up to 25 miles per hour in the afternoon,” the situation summary said. “Monday is forecast to bring stronger wind gusts exceeding 30 miles per hour, which could challenge suppression efforts.”
Just before noon Sunday, Cal Fire officials updated their situation summary to note that the fire has “remained in its current footprint” and fire activity decreased “significantly” overnight. The blaze remains at 478 acres, per the latest update.
“[Sunday’s] resources will continue to mop up and strengthen containment lines while actively working to defend structures,” the update, published at 11:55 a.m. Sunday, reads. “The fire continues to post a threat to high-tension power lines…forward rate of spread is stopped.”
A road closure is in place at the junction of the 138 and 173 freeways. Additionally, the 138 between Old Mill and the 15 Freeway is also closed. Evacuation orders and warnings issued Saturday remain in effect.
The origin of the Lake Fire is not known. No injuries were immediately reported.
According to Cal Fire, more than 520 personnel, three helicopters and 54 fire engines have been dispatched to the area near Silverwood Lake, which is a popular spot for recreation and camping in the San Bernardino mountains. Silverwood Lake State Recreation Area will remain closed to the public as the fire continues to burn, and those who must travel through the region are asked to consult official websites for road conditions and prepare in case evacuation orders and warnings change.
Also breaking out in the Inland Empire on Saturday was the Smiley Fire near Redlands, which reached 83 acres before crews started making significant containment progress.
