‘Long-Duration’ Heat Wave Again Cooking California, Raising Health and Wildfire Concerns

/in , /by /Los Angeles Timesby Grace Toohey

Another bout of prolonged heat has kicked off across California and much of the West, expected to again bring several days of triple-digit temperatures to most inland areas.

July’s second major heat wave isn’t forecast to be as extreme as the last event, which set several all-time records for high temperatures. Nevertheless, the National Weather Service predicted that it will be a “long-duration heat wave,” which creates uniquely dangerous conditions — especially when temperatures barely drop at night.

California’s Heatwave Evaporates Billions of Gallons of Water from Reservoirs

California’s current record-breaking heat wave in July has caused hundreds of millions of gallons of water in Lake Shasta and other major reservoirs in Northern California to disappear into thin air.

During the first nine days of July, 3,392 cubic feet per second of water — or about 2.2 billion gallons — turned into vapor and floated away into the atmosphere off the man-made Lake Shasta. During just one day — July 3 — 288.8 million gallons of water alone evaporated.

An intense and potentially record-setting ridge of high pressure is building across California and the West, threatening days and perhaps more than a week of a dangerous, life-threatening heat wave.

The worst of the heat will be centered in California’s Central Valley, where as many as 10 days or more of 110-degree heat looms. But just about all of California, stretching into western Oregon and western Nevada, will swelter for an extended period.

Extended California Heat Wave Brings Extreme Health, Fire Risk; Power Shutoffs Likely

/in , /by /Los Angeles Timesby Grace Toohey

Authorities are warning of extreme health and wildfire risks across California this week, as the longest heat wave of the year is set to kick off Tuesday, bringing triple-digit temperatures, with little overnight cooling, to the vast majority of the state.

“This is really just a long-duration heat event that will provide little to no overnight [temperature] relief,” said Antoinette Serrato, a National Weather Service meteorologist in Hanford, Calif. The heat wave is expected to bring dangerous temperatures through the Fourth of July holiday and into early next week in many areas, particularly across Northern California, the Central Valley and southwestern deserts, she said.

It’s about to heat up in San Diego County, with hot temperatures expected to linger for a bit.

The National Weather Service said a slight cooldown is anticipated for Monday, though short-lived as a warming trend sets in for the week of the Fourth of July holiday. The heat will be most felt away from the coast as high pressure moves into the region.

Long-Term Drought and Near-Term Heat Wave Take Toll on Arizona’s Desert Ecology

Frank Reichenbacher worries it will soon be over for his Tumamoc globeberry — a rare Sonoran desert vine that features a fruit that looks like a tiny watermelon and tastes like dirt.

For 41 years, Reichenbacher, an associate researcher at the University of Arizona’s Tumamoc Desert Lab, has followed the same three patches of the rare plants in southern Arizona — including one on Tucson’s Tumamoc Hill.

A winter of record snowfall in California, coupled with a triple-digit heat wave, is continuing to inundate Sierra trails and fill valley reservoirs with snowmelt run-off.

In a video posted on social media by a KCRA 3 viewer, ankle-deep water could be seen rushing over the rail to Wapama Falls in Yosemite National Park last week.
