The Hughes Fire near Castaic, California, has burned over 5,000 acres, prompting evacuations and school closures.

Just a few years after the ozone hole was detected via satellite, the industrialized nations of the world, meeting in Montreal in 1987, adopted what is known as the Montreal Protocol.

"A strong Santa Ana Wind event is expected to develop Monday and last through at least Tuesday," the National Weather Service said.

As wildfires continued to burn in Los Angeles, three fires broke out in San Diego County, prompting evacuation orders and warnings.

The Los Angeles haven’t spread in nearly a week, but the return of the Santa Ana winds to full strength could cause problems.

Meteorologists said there was a chance the winds would be as severe as those that fueled the Palisades and Eaton fires, but that different locations would likely be affected.

Much of inland San Diego County was whipped yet again by a strong Santa Ana wind event Monday into Tuesday, contributing to risky fire conditions as the region remains bone-dry.

The Santa Ana winds are expected to pick up again this week, making the Palisades and Eaton fires, among others, more difficult to contain as they continue to rage in Southern California.

Santa Ana winds finally delivered a big, direct hit on San Diego County Tuesday, gusting as high as 102 mph in the backcountry where a touch of long-overdue rain could arrive this weekend.

After a much quieter weekend, Southern California is experiencing a major shift in the weather pattern. The winds will peak Monday evening and overnight but extend into Tuesday morning.

Millions of California residents were placed under a red flag warning through Thursday amid threats of further fires with looming winds in the forecast, according to multiple reports.
