High temperatures continue in Siouxland, up in the nineties today and down to the 80s by tomorrow. There is a heat advisory in effect until 9:00 p.m. tonight.
The high heat is causing the concrete to buckle on some stretches of northwest Iowa roads.
Troy Clouse, with the Iowa Department of Transportation, says he and his crews responded to five reports of pavement blowouts during the weekend in Plymouth, Sioux, and Woodbury counties. Clouse told the Sioux City Journal they are making temporary repairs.
