Some voters were having to carry umbrellas and wear rain boots to the polls Tuesday as severe storms hit the Interstate 95 corridor along the East Coast on Election Day.
Areas from the Carolinas north through Washington, D.C. and southern New Jersey were expected to be affected.
Severe storms first struck overnight in Tennessee, where a woman died and two others were injured in a possible tornado in Rutherford County.
The weather also left some polling stations in Tennessee without power, the state’s elections coordinator, Mark Goins, told ABC News. Most polling places have generators and batteries to continue running their election operations, but at least one polling station without power in Knox County was forced to use emergency paper ballots, Goins said.
He said he does not expect the loss of power to cause a significant delay of election results.
Over 1 million Tennesseans had voted early before this round of storms hit the state.
In other parts of the country, rain was forecast to change to snow in the Upper Midwest and around the Great Lakes, with some snow accumulation possible from North Dakota to the Twin Cities.
Snow is also expected in the northern Rockies, with half a foot possible.
Warmer weather is expected in the southernmost parts of the country, from Los Angeles across to southern Florida.
