Millions of Texans are continue to lack power Wednesday amid frigid and icy conditions as yet another snow storm nears the US state. 

A previous cold front that brought an initial round of snow and ice storms knocked power offline in the state beginning over the weekend. About 2.7 million households continue to lack electricity, according to the state's power grid manager.

Texas Governor Greg Abbott has declared a state of emergency in every county in the state.

The National Weather Service is predicting that as much as half an inch (12.5 mm) of ice could accumulate late Wednesday evening in a region that spans eastern Texas, and flows further east into northern Louisiana and western Mississippi. An additional 1 to 2 inches (25-50 mm) of snow is possible in parts of Texas through Friday, the service said on Twitter.

A winter storm warning remains in effect for all but Texas' Gulf Coast counties.

The storm comes as record low temperatures continue to be recorded in several cities across the state, with temperatures not expected to rise above freezing in wide swathes of the state until the weekend.

At least 25 people have died in the Midwest and south as the regions cope with extreme weather, most of whom have died in Texas, according to NBC News.

Causes of death have included carbon monoxide poisoning, car accidents and fires started by people in their fireplaces that burned out of control./aa
