Lightning ignites more than 100 palm trees in San Pasqual Valley; crews contain fire near Safari Park

Multiple lightning strikes spark scattered palm-tree fires in rural North County

A series of lightning strikes ignited more than 100 palm trees in San Pasqual Valley, triggering a brush-and-tree fire that burned roughly two acres and prompted an extended monitoring operation as hot spots continued to smolder into the night.

The fire was reported Tuesday morning in the San Pasqual Valley area near the San Diego Zoo Safari Park. Fire crews contained the burning area to an estimated two acres, and no buildings were reported to be involved. Officials continued to watch the site after containment because individual trees and pockets of vegetation can retain heat and flare up again even after forward spread has been stopped.

Why palm trees can keep smoldering after flames are knocked down

Wildland firefighting operations frequently shift from active suppression to “mop-up” and monitoring when the immediate perimeter is secure but fuels inside the burn area remain hot. Palm trees, in particular, can burn unevenly, with embers persisting in fibrous material and within the crown, creating lingering smoke and the potential for rekindling. In this incident, firefighters reported smoldering trees into overnight hours, a sign that the response was moving into a prolonged overhaul phase focused on eliminating heat sources and preventing spot re-ignition.

Damage outlook for affected trees

Arborists assessing the aftermath indicated the struck and burning palms were unlikely to recover. Lightning-related tree damage can include internal charring and structural weakening that is not always visible from the outside, complicating decisions about removal, public safety and long-term site stabilization.

Context: San Pasqual Valley’s fire risk and recent nearby incidents

San Pasqual Valley sits in a wildland-urban interface corridor where wind, low humidity and seasonal fuel conditions can elevate fire risk. The area has also seen recent fires near State Route 78 and the Safari Park vicinity, including a nearly 50-acre brush fire in May 2025. More recently, a separate 100-acre fire in the valley drew attention after investigators revised the cause determination from intentional ignition to sparks thrown by a tire rim.

What happens next

• Crews may continue patrols until remaining heat is fully extinguished and the risk of flare-ups is reduced.
• Damaged palms may require hazard evaluation and potential removal if structural stability is compromised.
• Residents and visitors in rural parts of the valley may see lingering smoke from smoldering tree material even after containment.

The incident remained limited in size, with no reported structural involvement, but the volume of burning trees and lingering hot spots extended operations beyond the initial response.
