Supercell thunderstorms erupted across Iowa Thursday afternoon triggering multiple tornado sightings.

One of the strongest thunderstorm cells produced a tornado that ripped through the city of Marshalltown, Iowa.

A second severe thunderstorm produced two tornadoes simultaneously near the town of Altoona, which sits just a few miles northeast of the state capital, Des Moines.

This dangerous storm continued southeast and left behind a trail of damaged and destroyed buildings.

The map below indicates all of the tornado reports that the National Weather Service received from Iowa on Thursday. The several clusters of reports on the map are likely reports from the same tornado producing thunderstorm.

It will likely take several days to confirm the number of tornadoes across Iowa on Thursday, but Ubimet meteorologists estimate that at least 3 or 4 tornadoes will be confirmed.
