Massive smoke plumes rising from the Gifford Fire in the Los Padres National Forest have become symbolic of what could be California’s worst wildfire season in recent memory. These towering columns of smoke are part of a rare and dangerous phenomenon called plume-dominated fires.

Gifford Fire: Smoke Plumes

As of Tuesday, the Gifford Fire—burning across rugged terrain in Santa Barbara and San Luis Obispo counties—was only 7% contained, having already scorched over 82,000 acres, making it California’s largest blaze of the year. Crews have reported repeated sightings of plume collapses, where the smoke column collapses, pushing hot air and embers down in dangerous bursts.

"And then for the firefighters, they’re exerting themselves in extreme temperatures," said Santa Barbara County Fire Capt. Scott Safechuck. "That heat alone can be dangerous — and then you add the fire itself."

More than 500 homes have been evacuated, with nearly 900 additional structures under threat. State Route 166 remains closed east of Santa Maria due to fire activity.

Heat Wave Amplifies Wildfire Threat

Adding to the crisis is an intense heat wave baking much of the state. Temperatures are forecast to soar well above 100°F across inland California, with Palm Springs possibly reaching 118°F and parts of the Sacramento Valley climbing to 107°F or higher.

“This week will definitely bring those elevated fire weather conditions," said Adam Roser, meteorologist at the National Weather Service in San Diego. "The vegetation is still very dry … and these are definitely some of the hotter temperatures we've seen so far this summer."

Heat advisories are in effect across much of Southern California through Friday. Inland valleys and deserts—including San Diego, Riverside, San Bernardino, and Orange counties—are all expecting dangerous triple-digit heat.

Other Active Fires: Rosa and Gold Fires

While Gifford dominates the headlines, crews are also battling the Rosa Fire in Riverside County (holding at 1,200 acres with evacuations in place) and the Gold Fire in San Bernardino County, burning 348 acres in steep, rugged terrain.

Neither fire had any containment as of Tuesday morning, and both have been made more difficult by hot, dry conditions and short-range spotting — when embers jump ahead of the fire line.

A Fire Season Far from Over

Despite a relatively quiet early summer, California’s fire season is now in full swing, and officials warn that late summer and early fall are traditionally the most dangerous periods.

“This might be one of the longer [heat waves] this year,” said Bryan Lewis, meteorologist at the National Weather Service in Oxnard.

The LA Times notes that Southern California has already recorded record-breaking January firestorms, and the season still has months to go.

The fire risk across California is expected to remain elevated through next week, with only a slight drop in temperatures expected by the weekend.
