For nearly a month, millions of people across the American Southwest have sizzled, sweated and sweltered under a heat wave that refuses to let up.
Day after day, residents from Fresno to Phoenix have endured triple-digit temperatures and hot, restless nights that have offered little relief.
The water temperature around the tip of Florida has hit triple digits — hot tub levels — two days in a row. Meteorologists say it could be the hottest seawater ever measured, although some questions about the reading remain.
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.
An extreme heat wave in the Southwest could pose a risk to Lake Powell’s water levels, which have been steadily increasing all summer.
After an extended drought period, Lake Powell, which is in Utah and Arizona, reached drastically low levels last summer, but levels began rising in earnest in April after California experienced a wet winter. The above-average snowfall in the mountains led to an increased snowpack melt that has continued to supplement Lake Powell, as well as Lake Mead in Arizona and Nevada, this summer.
After weeks of uncertainty, forecasters say an incoming California heat wave will trigger rapid snowmelt on the slopes of the Sierra Nevada and cause more flooding in portions of the San Joaquin and Owens valleys this week.
Temperatures in Central California are forecast to climb into the high 80s and mid-90s beginning Wednesday and into the weekend, with the potential for some areas to approach daily records.
Mount Shasta, the widely recognizable face of California’s far north, has lost almost all its defining snow cover for a second straight year.
Another summer of scorching temperatures, punctuated by the recent heat wave, has melted most of the mountain’s lofty white crown, typically a year-round symbol of the north state’s enduring wilds.
It was just before 9 a.m. and already nearing 100 degrees as I stared out at the menacing steel pillars of the U.S.-Mexico border wall, in California’s far southeastern corner. My long-sleeve shirt stuck to my skin. Sweat dripped down my back.
The operator of the state’s power grid warned residents Tuesday to prepare for possible rolling blackouts, as a drawn-out heat wave reaches its peak and drives electricity demand to an anticipated record level.
VIDEO: The heat wave is stretching into the seventh day and relief is not expected anytime soon which means the demand for energy is straining the grid. The California Independent System Operator has issued a Flex Alert asking residents to conserve energy during peak use but as KPBS reporter Alexander Nguyen shows us it is also tapping other sources for energy.
As California grapples with drought, a record heat wave and persistent wildfires, one state agency is turning to the beaver in its battle against climate change.
The large rodents, according to researchers, are resourceful engineers capable of increasing water storage and creating natural firebreaks with their dams.
Water production at the Carlsbad desalination plan has been temporarily reduced to conserve power while the heat wave stresses California’s electric grid.
The Claude “Bud” Lewis Carlsbad Desalination Plant, which can produce up to 50 million gallons per day, typically accounts for about 1% of peak electricity demand in San Diego Gas & Electric’s service area.
