At least 30 dead, several million still without power in U.S. after days of extreme weather
Utility crews raced Wednesday to restore power to nearly 3.4 million customers around the U.S. who were still without electricity or heat in the aftermath of a deadly winter storm, and another blast of ice and snow threatened to sow more chaos.
The latest storm front was expected to bring more hardship, especially to states that are unaccustomed to such frigid weather — parts of Texas, Arkansas and the Lower Mississippi Valley.
“There’s really no letup to some of the misery people are feeling across that area,” said Bob Oravec, lead forecaster with the U.S. National Weather Service, referring to Texas.
The system was forecast to move into the Northeast on Thursday. More than 100 million people live in areas covered by some type of winter weather warning, watch or advisory, the weather service said.
At least 30 people have died in the extreme weather this week, some while struggling to find warmth inside their homes. In the Houston area, one family succumbed to carbon monoxide poisoning from car exhaust in their garage. Another perished as they used a fireplace to keep warm.
Record low temperatures were reported in city after city. Scientists say the polar vortex, a weather pattern that usually keeps to the Arctic, is increasingly spilling into lower latitudes and staying there longer, and global warming is partly responsible.
Utilities from Minnesota to Texas and Mississippi have implemented rolling blackouts to ease the burden on power grids straining to meet extreme demand for heat and electricity. In Mexico, rolling blackouts Tuesday covered more than one-third of the country after the storms in Texas cut the supply of imported natural gas.
The worst U.S. power outages by far have been in Texas, where three million homes and businesses remained without power as of midday Wednesday. The state’s power grid manager, the Electric Reliability Council of Texas, said electricity had been restored to 600,000 homes and businesses by Tuesday night. Officials did not know when power would be restored, but council president Bill Magness said he hoped many customers would see at least partial service restored by later Wednesday or Thursday.
Widespread power loss
More than 200,000 additional customers were in the dark in four Appalachian states, and nearly that many in the Pacific Northwest, according to poweroutage.us, which tracks utility outage reports.
Oklahoma’s largest electric utility reported no outages Wednesday, a day after rolling blackouts in and around Oklahoma City stopped electric-powered space heaters, furnaces and lights in –8 C weather. But Oklahoma Gas & Electric warned customers of the potential for more short-term service interruptions due to the extreme cold and high demand for natural gas.
Nebraska also avoided another round of rolling power outages as subzero temperatures started to ease.
Entergy imposed rolling blackouts Tuesday night in Arkansas, Louisiana, Mississippi and Southeast Texas at the direction of its grid manager, the Midcontinent Independent System Operator, according to a statement from the New Orleans-based utility.
The Southwest Power Pool, a group of utilities covering 14 states, said the blackouts were “a last resort to preserve the reliability of the electric system as a whole.”
The weather also caused major disruptions to water systems in several southern U.S. cities, including in Shreveport, Louisiana, where city fire trucks delivered water to several hospitals, and bottled water was being brought in for patients and staff, Shreveport television station KSLA reported.
Carbon monoxide poisoning incidents
In Austin, Houston and other cities, residents were asked to stop letting water drip from pipes, a practice to prevent freezing, because of a major drop in water pressure. Houston residents also were told to boil their water — if they had power — because the pressure drop was allowing bacteria to seep into the pipes.
In the southwest Louisiana city of Lake Charles, Mayor Nic Hunter said Wednesday that water reserves remained low even after power was restored, and that local hospitals were faced with the possibility they might have to transfer patients to other areas because of low water pressure.
