The Springs fire in Riverside county has grown to 3,500 acres, prompting local authorities to issue several evacuation orders. The fire is concentrated in an area mostly north and east of Lake Perris, burning portions of the surrounding state recreation area.

The fire was reported in the 15900 block of Gilman Springs Road in Riverside County, just before 11 a.m. Gusty Santa Ana winds were forecast for much of Southern California on Friday.

When scientists applied a new model of human survivability that takes into account the body's ability to function and stay cool depending on age, they found all six events had seen non-survivable periods for older people who could not find shade.

"This is going to help fill that gap in minutes to hours lead time that's vital to know where the heaviest rain is going to hit," Ralph said. "And when and what communities are going to be affected so people in the preparedness community and water resource management community can take action to help protect people's lives and property."

Heavy rain and thunderstorms affected much of Greece, with southeastern areas experiencing the most severe conditions, including flooding and stranded vehicles.

Flash flooding has been a major problem in recent days in places such as Maui, Molokai and the Big Island, where rain had been falling between 1 and 2in (2.5 and 5cm) an hour overnight, according to the Hawaii emergency management agency.

The storm from Sunday into Monday has the potential to become a bomb cyclone, which occurs when central pressure drops at least 0.71 inches of mercury (24 millibars) in 24 hours or less. That rapid strengthening would generate an expansive and intense wind field.

Flash flooding is a real risk and can occur quickly, without much warning. We urge people to steer clear of floodwaters and never drive through a flooded road regardless of how safe you think it may be.

Showers moving into the region from the Central Coast should bring steady rain to Ventura and Los Angeles counties Thursday morning, with frosty temperatures pushing snow levels lower than normal, potentially impacting commuters along the Grapevine, according to the National Weather Service. "Steady precipitation will taper off to showers by late this afternoon and become confined to the mountains by late tonight," the weather service posted in a Thursday morning forecast.

In November 2025, a massive storm rolled across the lower Mekong River delta, dumping multiple inches of rain onto the wide, flat river plain that covers much of Cambodia. The river rose and rose. The force of the water churned up mud from the river bottom. The muddy water flowed downstream and rushed into the many farming and fishing towns that line the Mekong's banks.

Californians looking to resume their weekly commute Tuesday awoke to see several major roads closed after heavy rains drenched much the state Monday - with the expected precipitation far from over. Among the closures was a section of Highway 1 through Big Sur, which state officials just weeks ago celebrated reopening for the first time in three years. The road closed Monday after rockslides left "debris in the roadway at multiple locations," according to the California Department of Transportation.

LIVE RADAR: Track storms as they move through the Bay Area with Live Doppler 7 Take a look at the chart above -- we will give each storm a number with 1 being the lightest type of storm and 5 being the most severe. This way you'll know what to expect. Number 1 means a light storm with 1/2 an inch of rain or less and likely lasting a few hours or less. Number 2 is a moderate storm with 1/2 an inch to one inch of rain forecast and could include scattered power outages.

A powerful storm system arrives Sunday with heavy rain, thunderstorms and dangerous waves, posing threats of flooding and debris flows through early next week. The strongest impacts hit late Sunday through Monday, with 1-2 inches of rain expected in valleys and coasts, twice as much in mountains. High-surf advisory expected Monday through Thursday, with waves exceeding 10 feet across all Southern California beaches and a 20-30% chance of damaging sets midweek.
