WASHINGTON: Swaths of the United States braced for more snow and punishingly low temperatures on Wednesday as millions in the east dug out from a previous round of severe winter weather that left at least five people dead.

The latest storm, already bringing precipitation to the West, was expected to tear across the country this week, bringing an Arctic blast to northern regions and prompting weather advisories or warnings in dozens of states from California to Maine.

`A potent Arctic front drops southward from Canada on Wednesday and this will herald the arrival of the coldest temperatures so far this season for the Northern Plains, with subzero lows becoming a reality for Montana and the Dakotas, and highs remaining below freezing as far south as Oklahoma by Friday,` the National Weather Service (NWS) said in a statement.

That comes on top of fierce storms that brought tornadoes in the South, dangerous flooding in the east and blizzards through the Great Lakes region and elsewhere, disrupting thousands of commercial flights and prompting governors to declare states of emergency.

The NWS forecast `several feet of heavy snow and strong winds gusting to 60 mph` (96 kilometres per hour) through Wednesday in the northwest`s Cascades and parts of the Rocky Mountains, with the storm then barrelling eastward and bringing `blizzard conditions` to the Midwest.

Meanwhile, tornadoes on Tuesday ripped through the Florida panhandle, where drone images showed downed trees and damaged buildings with roofs torn off. At least five storm-related deaths have been recorded, including an 81-year-old Alabama woman whose mobile home was reportedly struck by a tornado.-AFP
