(Des Moines) Three weak tornadoes surrounded by powerful winds. That’s how the survey team from the National Weather Service described their view of the damage caused by Sunday’s storms.
“The tornado damage scale goes from EF-0 to EF-5 and we had a weakest end of the scale with two EF-0 tornadoes and one EF-1 tornado,” stated Carl Jungbluth, with the National Weather in Des Moines. “So an EF-1 tornado the house that was hit by Dallas Center had most of the shingles off and lots of the outbuilding damage and trees up rooted that type of thing.”
Jungbluth says the first tornado was southwest of Adel and caused minimal damage in farm fields and then ended right before it got to the city of Adel. The second tornado, the strongest of the three, was east-southeast of Dallas Center. It had peak winds of 100-miles an hour and caused significant tree damage. The third touched down southeast of Slater and went back up several times, with a total damage path of about five-miles.
