A "particularly dangerous situation warning'' has been issued for L.A. and Ventura counties due to dangerous winds and very low humidity.

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.

One of the biggest stories of 2025 thus far has been the wildfires in California. A common occurrence in that state, wildfires are often fueled by a combination of drought and terrain. The terrain allows for the development of Santa Ana winds that cause any fire to spread very quickly.

Topography matters, too — treeless mountain peaks are typically windier without those trees, or buildings, to slow the winds. And different parts of Earth — water and land — heat from sunlight at different rates, which shapes wind.

Gusts of up to 70 mph are possible along the coast and valleys, and in the mountains, up to 100 mph, the National Weather Service said. Parts of L.A. County, and most of Ventura County, are at highest risk.

Firefighters in Southern California are once again battling a wildfire, this time in Castaic in Los Angeles County, north of Los Angeles itself. Evacuation orders have been issued for the surrounding areas.

And this week the so-called Santa Ana or "Devil" winds are back ... The warnings cover the areas of Calabasas and Agoura Hills, Eastern San Gabriel Mountains, Malibu Coast and Santa Clarita ...

The Santa Ana winds are expected to strengthen into Sunday morning with gusts of 30 to 50 mph in coastal areas, and up to 70 mph in the mountains.

The Santa Ana winds fanning wildfires that have killed at least 25 people in Southern California and destroyed more than 10,000 houses, businesses and other structures in Greater Los Angeles are flaring up again.

California Governor Gavin Newsom has deployed fire engines, water-dropping aircraft and hand crews across the region—to enable a rapid response if a new fire does break out, according to The Associated Press.

As winds across the Southern California area are calmer than their peak and firefighters are making progress, the threat to the fire-weary region remains with Santa Ana winds expected to continue in the coming days.
