Southern California lashed by tropical storm after record-breaking heatwave

Southern California lashed by tropical storm

Southern Californians welcomed cooler temperatures and spotty rain Saturday from a tropical storm veering off the Pacific coast days after a relentless heat wave nearly overwhelmed the state’s electrical grid.

Officials braced for flooding in coastal and mountain areas from the storm and feared powerful winds could expand the massive Fairview Fire about 75 miles (121 km) south-east of Los Angeles.

But minimal flooding was reported early Saturday and crews made significant progress on the fire and said they expected full containment on Monday. More than 10,000 homes and other structures were threatened by the blaze.

The National Weather Service forecast an end to the grueling heatwave in the Los Angeles area Saturday though heat and wind advisories remained in effect through the evening, and warned of possible flooding in mountain areas and some beach communities.


'Triple-dip' La Niña is on the way. Here's what it means for weather in the US.

Triple Dip La Nina won['t go away

La Niña just won't go away.

Meteorologists say that for the third straight year, La Niña will persist throughout the winter in the Northern Hemisphere. This is the first "triple-dip" La Niña of the century, according to a recent update from the United Nations' World Meteorological Organization.

This La Niña began in September 2020.

The La Niña climate pattern is a natural cycle marked by cooler-than-average ocean water in the central Pacific Ocean. It is one of the main drivers of weather in the United States and around the world, especially during late fall, winter and early spring.

It's the opposite to the more well-known El Niño, which occurs when Pacific ocean water is warmer than average. While this would be the first "triple-dip" La Niña this century, it's not unprecedented for the pattern to last more than nine months to a year, which is typical for a La Niña, according to ABC News.


Flash flood watch under way for 80m in eastern US as heatwaves broil west

Extreme heat in US west, flooding in US east

More than 80 million people in the eastern US were under flash flood watches late on Monday, marking still more extreme weather in a country reeling from record heatwaves in some regions, as the US increasingly feels the effects of the climate crisis.

In Georgia, the threat of torrential downpours became a reality Sunday afternoon, spurring a flash flood emergency in western portions of the state, CNN reported.

The “one-in-1,000-year rainfall event” caused rivers and creeks to swell. Authorities carried out water rescues as homes and businesses were flooded; meteorologists believe that the area could see another one to three inches of rain, according to the news network.

Potentially dangerous weather is not limited to the area stretching from southern Appalachia to New England. In the US west, residents are facing the possibility of power outages on Monday and early this week while temperatures continue to soar.


Two killed in Northern California wildfire as firefighters continue to battle blazes

Fires continue in California

Two people have died in a wildfire that ripped through a Northern California town, a local official has said, as firefighters in the far north of the state on Sunday battled blazes that forced evacuations and destroyed dozens of homes.

“There’s no easy way of putting it,” said Siskiyou county sheriff Jeremiah LaRue as he shared the news of the fatalities on Sunday afternoon during a community meeting held at an elementary school north of the rural community of Weed. He did not immediately provide names or other details including age or gender of the two people who died.

Both LaRue and other officials said it was not clear when people would be allowed back into their homes, and when power would be restored for the people still without it.


A weeklong heat wave in California and other Western states will test the power grid

Heat wave in California

A long, intense wave of excessive heat is hitting much of the Western United States for the next week.

The region should anticipate "a prolonged and possibly record breaking heat wave," with little relief overnight, the National Weather Service says. Heat watches and advisories stretch from Arizona to Washington state.

"In addition, the warmth combined with very little moisture and low relative humidities, will contribute to an elevated wildfire risk across parts of the northern Great Basin and northern High Plains," the agency said.

Across California, temperatures are expected to be more than 10 degrees above normal, warns the organization that manages the flow of much of the state's electricity.

The California Independent System Operator expects that demand on Labor Day will reach the highest point so far this year, and that it will ask Californians to take energy conservations steps.


Jackson, Mississippi, to go without reliable drinking water indefinitely

Mississippi without waterJackson, Mississippi, will go without reliable drinking water indefinitely, officials said on Monday, after pumps at the main water treatment plant failed, leading to the emergency distribution of bottled water and tanker trucks for 180,000 people.

The city linked the failure to complications from the flooding of the Pearl River, but Governor Tate Reeves, who declared a state of emergency, said the cause was unknown and that the city-run water treatment plant had been poorly operated and understaffed for years.


Major sea-level rise caused by melting of Greenland ice cap is ‘now inevitable’

Major sea level caused by Greenland icecap

Major sea-level rise from the melting of the Greenland ice cap is now inevitable, scientists have found, even if the fossil fuel burning that is driving the climate crisis were to end overnight.

The research shows the global heating to date will cause an absolute minimum sea-level rise of 27cm (10.6in) from Greenland alone as 110tn tonnes of ice melt. With continued carbon emissions, the melting of other ice caps and thermal expansion of the ocean, a multi-metre sea-level rise appears likely.

Billions of people live in coastal regions, making flooding due to rising sea levels one of the greatest long-term impacts of the climate crisis. If Greenland’s record melt year of 2012 becomes a routine occurrence later this century, as is possible, then the ice cap will deliver a “staggering” 78cm of sea-level rise, the scientists said.
