MINNEAPOLIS (AP) - U.S. Sen. Amy Klobuchar says federal disaster officials will start assessing Minnesota's flood damage this week.

Klobuchar says the Federal Emergency Management Agency will begin compiling its preliminary damage assessment on Tuesday. She says the agency's assessment will take about a week.

The assessment starts the process of bringing federal help to the state and counties with public infrastructure damage.

The National Weather Service says 2014 has been the wettest year on record in the Twin Cities, with 25.82 inches of precipitation. That far surpasses the old record of 22.2 inches set in 1965.

Meanwhile, heavy rain Friday caused part of the roof of St. Mary's Catholic School in Morris to collapse. Officials say no one was hurt.
