The Alisal Fire ignited on October 11, 2021, in the Santa Ynez Mountains and was driven south by extreme winds with gusts up to 70 mph. The blaze grew explosively, burning to the Gaviota Coast where it jumped all lanes of Highway 101, forcing a complete closure of the region's primary transportation corridor. Its origin in dense chaparral that had not burned since the 1955 Refugio Fire underscored the area's cyclical fire danger.

Fueled by dense, 66-year-old vegetation and powerful northwest winds, the fire exhibited extreme behavior from its onset near Alisal Reservoir. Within hours, it had crested the Santa Ynez range and raced three miles downhill to the Pacific coast. The fire's rapid growth was compounded by weather conditions too dangerous for aerial firefighting, grounding all air tankers on the first day and preventing an effective initial attack.

The fire's most significant impact was on transportation and public safety. After spotting across all four lanes of Highway 101, the blaze forced an extended closure between Buellton and Goleta, creating hours-long detours for commuters and commercial traffic on State Route 154. Mandatory evacuation orders were issued for remote ranches and communities along the Gaviota Coast, including Refugio and El Capitan State Beaches. While structural losses were minimal due to the area's sparse population, the fire threatened ranches, the Tajiguas Landfill, and the coastal railroad line.

Igniting in nearly the same location as the 1955 Refugio Fire, the Alisal Fire served as a modern validation of historical fire patterns on Santa Barbara's South Coast. The incident highlighted the vulnerability of the Highway 101 corridor to wind-driven wildfires originating in the coastal mountains, a recurring threat that disrupts a critical statewide economic and travel artery.
