Election Day is poised to bring heavy rain, strong wind gusts and even potential tornadoes to various states across the U.S. where voters will be casting their ballots in competitive races. In the South, severe weather threats are forecast in northern Georgia, where Democrat Stacey Abrams is vying to become the nation's first female African-American governor in a high-profile race against the state's GOP Secretary of State Brian Kemp.

Further south, pop-up thunderstorms may strike the three south Florida congressional districts where Republicans are defending against well-funded challenges by Democrats. Florida voters will also be choosing between Democrat Andrew Gillum or Republican Ron DeSantis as their next governor and between Sen. Bill Nelson and Governor Rick Scott for the Senate seat.

There's also a risk of flash floods between New York and northern New England, a region hosting multiple gubernatorial elections and some tight House contests, including the race between Democrat Antonio Delgado and Republican Rep. John Faso in New York's Hudson Valley, and the Staten Island clash between GOP Rep. Dan Donovan and progressive challenger, Max Rose.

Pennsylvania is looking at heavy rain in the morning and early afternoon. Democrats hope to pick up some seats in the state's new court-ordered congressional district map — particularly in the suburbs around Philadelphia. Severe rain is in the forecast in New Jersey, too, where Democrats are seeking to flip several Republican-held suburban districts while helping Sen. Bob Menendez avoid a humiliating upset.

CBS News elections and surveys director Anthony Salvanto points out that historically, while weather has depressed turnout in races that are not competitive, it has not been a factor in competitive races. That is, in a close race, people are willing to stand in line in the rain or wind.
