In Texas, wildfires have scorched nearly 400 square miles and destroyed dozens of homes.
One fast-moving blaze in west Texas spread to more than 60,000 acres of land in Jeff Davis county on Sunday. It destroyed about 40 homes in Fort Davis before moving north and west.
In Midland County, another fire burned 16,000 acres and more than 30 homes. And a fire in north Texas scorched 71,000 acres.
"It could be one of the worst grass fires in the state for a number of years," said Rick Nessner of the Combine Volunteer Fire Department.
Meanwhile, in North Dakota and Minnesota flooding - not fire - is the problem.
The Red River has now crested, but its tributaries are at record levels. Roughly 70 miles of roads, including an interstate highway, are either closed or under water.
Hundreds of National Guard members are standing by to help with evacuations if necessary.
