Election Day storm to bring rain and strong winds to central US as voters head to the polls
A powerful storm carrying moisture from the tropical Pacific was heading for the central United States, with forecasters warning it would bring rain to much of the region on Election Day, Tuesday 3 November, and could affect turnout in key midterm races.
The system was due to cross into the country on Saturday night, 31 October, after first soaking the Southwest. Heavy rain was expected over the Four Corners states of Arizona, New Mexico, Utah and Colorado on Sunday into Monday, with a serious risk of flash flooding. Flash flooding had already closed part of the Lake Mead Highway in Henderson, Nevada, on 30 October, and Fox Weather reported flooding in Las Vegas and swiftwater rescues in Phoenix on Friday.
By Tuesday, soggy weather was expected across a wide area, from the Great Plains and Upper Midwest to the Lower Mississippi Valley and the western Gulf Coast. Thunderstorms on the storm’s southern side could turn severe from eastern Texas into Arkansas, Louisiana, Mississippi and Tennessee, while Kansas faced wind gusts of 30 to 40 miles per hour and Nebraska up to 50. Rain was expected in Iowa, with the heaviest totals in the east from Monday evening into Tuesday midday, and across Michigan for at least part of the day. Eastern and coastal Texas also faced rain, with a few severe thunderstorms possible.
Why it matters
Bad weather on polling day can keep voters at home: studies have found that rain tends to suppress turnout, while sunshine has the opposite effect. With control of Congress at stake, even a small dip in turnout in close races in Iowa, Kansas, Michigan and Texas could matter. More than 49 million people had already cast ballots through early voting, but millions more were still due to vote on the day.
What happens next
Forecasters said the outlook could still change as confidence grows in the storm’s path over the weekend, so voters in affected states should check local forecasts and allow extra time to reach polling places. After Tuesday, the system was expected to keep moving east, bringing more rain to the eastern United States later in the week, while high-elevation snow continued in the Rockies.
