Hurricane Michael made landfall along the Florida panhandle Wednesday and is expected to wreak havoc on many states and congressional districts as it winds up the east coast of the southern United States.

The Category 4 storm, which President Donald Trump dubbed a “massive tornado” Wednesday (note: the storm is not a tornado), will test the commitment of campaign volunteers in Florida, North Carolina, and Virginia, where incumbents and newcomers are locked in tight races with the 2018 midterm elections less than four weeks away.

Here are six neck-and-neck races that Hurricane Michael could affect.

Florida Senate

Incumbent Democratic Sen. Bill Nelson faces GOP Gov. Rick Scott in a race that Inside Elections with Nathan L. Gonzales rates a Tossup. Though Hurricane Michael is expected to shred portions of his state, the storm could be a political boon for Scott, who as governor will almost certainly be seen on TV marching through floodwaters, shelters, wreckage and first responder stations in the coming weeks. Meanwhile, Nelson’s senatorial obligations will keep him in Washington, D.C. — voting down presidential appointments.

Virginia, 2nd District

In addition to fending off an investigation into ballot petition fraud by at least four of his campaign staffers, GOP Rep. Scott Taylor is also fending off a Democratic challenge from Navy veteran Elaine Luria. Taylor’s district, rated Tilts Republican by Inside Elections, includes oceanside Virginia Beach, an area prone to severe flooding.
