The near-record temperatures are expected to last into this weekend, forecasters say. While it's not unprecedented to see high temperatures climb toward 90F on an April day, the length of such an April heatwave is rarely seen.
Parts of Los Angeles will probably see rain after 11 p.m. Saturday, with scattered showers anticipated on Sunday afternoon before 2, and a potential for thunderstorms in some parts of the city.
Not only will temperatures break March monthly records, but this heatwave will even break April records. Over the next week, around 800 high temperature records are forecast to be neared, tied or broken at 165 locations in Western and Central states - some by more than 10 degrees - with unusual warmth set to linger into late March.
In Turkana, the land is rugged, roads disappear into dust, and villages are scattered across vast distances in a county of just more than a million people. Despite it being the rainy season, weather experts warn that Turkana and other arid regions may receive little relief. Authorities say drought is once again taking place, with 23 of Kenya's 47 counties affected.
During this heat wave, "not only are daily temperature records likely to be broken across the region, but even the high temperature records for any day in the entire month of March," the National Weather Service said in a Tuesday morning forecast.
The Colorado River is an interconnected system, sustained by Rocky Mountain snowpack, rainfall and groundwater. It is fragile, and under increasing stress. Two and a half decades into this century, the river that built the modern West has 20% less water flowing through it than it did on average in the last century. As heat and drought intensify, so do the stakes: Failure to recognize the severity of changing conditions, managing the river in parts without considering needs of the whole and inadequate planning for long-term shortages put the future of all the basin at risk.
"So whenever people think about hot weather, they always talk about the temperature," he says. "There's two issues with that. First of all, most people don't realise that the temperature is measured in the shade. So if you're in direct solar radiation, the amount of heat stress you're exposed to is much greater as it will stress your body out a lot more."
Over time, the water evaporated to form the smaller, brinier Owens Lake. Indigenous Paiute people call the Owens Valley Payahuunadü, 'the land of the flowing water'. Today, Owens Lake is a 'Dusty Vestige of the Old West', as NASA described a photograph of the lake taken from space.
While cold-stunned iguanas fall from trees in Florida and videos circulate of frozen "exploding" trees in the Northeast, Southern California is working up a sweat. A midwinter heat wave has descended on much of the state and is expected to spike temperatures as much as 20 degrees above normal in the coming week. The summer-like heat is thanks to a ridge of high pressure lingering high in the atmosphere that extends through the San Francisco Bay Area and into the Pacific Northwest.
