DAVENPORT, Iowa (AP) — The deep freeze has prompted several eastern Iowa schools to cancel classes or start the school day late. The Davenport district and nearby Bettendorf and Muscatine schools canceled classes Friday. Davenport’s air temperature earlier this morning was minus 12, with a wind chill of minus 29. Wind at the time was reported at 8 mph. Late starts were scheduled for the Decorah, Louisa-Muscatine, Wapello and other districts, including many in southwest Iowa.

Alliant Energy says its crews are working on restoring power to more than 900 customers in frigid Clayton County who have been without power since about 5:15 a.m. The utility says it expects to have the electricity back on by 10 a.m. It’s unclear whether the cold caused the outage, however. Forecasters say the numbing cold is expected to linger into next week.
