US Midterm Elections 2026: Election Day weather forecast warns of flooding, storms and possible tornadoes across several states-here's which states are affected

Millions of Americans are heading to the polls on Tuesday, November 3, but the weather could make voting more difficult in several parts of the country. Heavy rain, flash flooding and thunderstorms have already disrupted polling arrangements in some areas. Florida has been among the hardest-hit states, with floodwaters forcing officials to relocate polling locations. Other states, including Texas, Oklahoma, Arkansas and Mississippi, are also facing storm risks. The inputs for this report are taken from various outlets- NBC News, NYT and Fox4.

With competitive Senate and House races underway, campaigns will be watching closely to see whether poor weather affects voter turnout.

Which States Could Face the Worst Weather on Election Day?

Florida is dealing with some of the most serious conditions. Days of heavy rainfall caused flash flooding across parts of the Atlantic coast, with some areas receiving more than a foot of rain. One storm brought as much as 22 inches in 24 hours.

Officials moved at least 18 polling locations across Brevard, Highlands, Indian River, Martin, Okeechobee, Palm Beach and St. Lucie counties. CNN reported that the number had reached 19. Gov. Ron DeSantis declared a state of emergency in seven counties.



Texas could see early morning thunderstorms, particularly in the eastern part of the state, before conditions improve by early afternoon. Oklahoma and Arkansas also experienced severe storms overnight, while forecasters issued a tornado watch that lasted until around 2:45 a.m. local time, as per National Weather Service.

Mississippi faces a risk of severe thunderstorms, heavy rain, strong winds and possible tornadoes, especially in northern areas. Kansas could see early morning showers before skies clear.

Iowa, Wisconsin and Minnesota may experience lighter rain throughout much of the day, with periods of showers.

Flooding and Storm Damage Disrupt Voting Arrangements

The problems extend beyond Florida. In Oklahoma, a tornado with estimated peak winds of 100 mph damaged the Keyes Community Center in Cimarron County. A damaged roof and collapsed wall made the building unsafe for voting, forcing officials to relocate a polling place.

Utah Lt. Gov. Deidre M. Henderson declared a state of emergency after historic flooding in the Four Corners region. She also allowed voters isolated by floodwaters in San Juan County to request and return ballots electronically.

Colorado introduced a similar arrangement for voters in La Plata and Archuleta counties.

Flooding has also caused widespread damage in parts of Colorado, where emergency crews have been searching for stranded people. Residents along the Animas River faced evacuation warnings. Arizona, meanwhile, reported record rainfall, deadly flooding and power outages.

Could Bad Weather Affect Election Day Voter Turnout

Research shows that heavy rain can make some people skip voting. Brad Gomez, a professor of political science at Florida State University said that studies of elections from 1948 to 2000 found that turnout dropped by about eight-tenths of a percentage point for every inch of rain above a county’s average.

Kasper M. Hansen of the University of Copenhagen also found that occasional voters, younger people are more likely to stay home when it rains.

However, early voting and mail ballots have reduced the potential impact of Election Day weather, according to Princeton University professor Thomas Fujiwara.



The weather may not determine the outcome of competitive races in Texas, Iowa, Kansas, Mississippi and Florida. But with polling locations disrupted and storms still possible, its effect on turnout will remain worth watching.
