DES MOINES (AP) — Recent rain coupled with an expected warm-up have some Iowa river communities warily watching out for flooding that has already affected the state’s eastern region.

The National Weather Service said temperatures across Iowa will warm up in the next few days. The melting snow could be troublesome for a swath of northern Iowa where runoff is likely because the ground is frozen.

A recent storm system Sunday into Monday produced heavy powder for the region. The Mason City area got 10 to 13 inches of snow, while Fort Dodge had at least 10 inches.
