100 million Americans brace for more cold, ice and snow

AUSTIN, Texas (AP) — Winter weather that has overwhelmed power grids unprepared for climate change and left millions without electricity in record-breaking cold kept its grip on the nation’s midsection Wednesday.
At least 20 people have died, some while struggling to find warmth inside their homes.
In the Houston area, one family succumbed to carbon monoxide from car exhaust in their garage; another perished after flames spread from their fireplace.
Blame the polar vortex, a weather pattern that usually keeps to the Arctic, but is increasingly visiting lower latitudes and staying beyond its welcome.
Scientists say global warming caused by humans is partly responsible for making the polar vortex’s southward escapes longer and more frequent.
More than 100 million people live in areas covered Wednesday by some type of winter weather warning, watch or advisory, as yet another winter storm hits Texas and other parts of the southern Plains, the National Weather Service said.
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 as record low temperatures were reported in city after city.
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.
Nearly 3 million customers remained without power early Wednesday in Texas, Louisiana, and Mississippi, more than 200,000 more in four Appalachian states, and nearly that many in the Pacific Northwest, according to poweroutage.us, which tracks utility outage reports.
The latest storm front was predicted to bring snow and ice to East Texas, Arkansas, and the Lower Mississippi Valley before moving to the northeast on Thursday.
Winter storm watches were in effect from Baltimore to Boston, and Texas braced for more icy rain and possibly more snow.
