Winter storm updates: Dozens dead across US in wake of massive snowfall, deep freeze

Austin city officials confirmed on Sunday that at least one person has died during the ongoing winter storm.

Austin-Travis County EMS confirmed to ABC News that one person was found dead in the parking lot of an abandoned gas station early Sunday morning. Due to the circumstances, the presumed cause is hypothermia; however, ATCEMS cannot officially rule on causes of death. Only the medical examiner can make that determination.

The identity of the individual has not been released.

Snow totals in the Northeast so far have reached: 13 inches in Bridgeport, Connecticut; 12 inches in Ridgefield, New Jersey; 11 inches in the Bronx in New York City; and 15 inches in Midland in western Pennsylvania.

The massive winter storm is bringing a blast of freezing air, which is especially dangerous for the South.

The wind chill -- what temperature it feels like -- dropped Sunday to 6 degrees in Dallas; 7 degrees in Little Rock, Arkansas; minus 3 degrees in Oklahoma City, Oklahoma; minus 2 in St. Louis, Missouri and 15 in Nashville. The storm knocked out power to hundreds of thousands of customers in the South, so people could be stuck without crucial heat during this deep freeze.

The dangerous cold is also invading the Northeast. The wind chill on Sunday plummeted to 6 degrees in New York City, and 1 degree in Buffalo, New York.

Over 900,000 customers are without power from the massive winter storm, with Tennessee, Mississippi, Louisiana and Texas hit the hardest.
