OSCEOLA, Iowa - Straight-line thunderstorm winds caused a several dozen trains cars to derail as thunderstorms, including one that produced a tornado, moved through central Iowa early Sunday morning.

Storm-ReportsThe train derailed shortly after 2 a.m. a few miles west of Osceola in Clarke County. Officials weren't sure if a tornado or straight-line winds had caused the derailment. A storm survey crew from the National Weather Service said Sunday afternoon that it was straight-line winds of 60-70 m.p.h. from a thunderstorm, not a tornado, caused the trains cars to blow off the tracks.

Several farm buildings were destroyed in the area as well.

Tornado warnings were in effect when emergency management officials reported a tornado on the ground one-mile west of Ogden at about 3:52 a.m.

Severe storms did cause storm damage in parts of Dallas County with reports of trees down in Dallas Center. Our crews have also located tree damage at City Park in Bouton and in Decatur County.

At the height of the storms, more than 3,000 MidAmerican Energy customers were without power. No injuries have been reported.

The National Weather Service will be dispatching a storm survey team to examine damage in an effort to determine how many tornadoes touched down Sunday and their strength.

Sunday's tornado comes one week after an EF1 tornado struck Lake City in Calhoun County. That tornado, with winds of 100 m.p.h., struck South Central Calhoun High School while more than 100 people were inside the building during an awards ceremony. No one was injured in that storm.
