(Updated 7:38-a.m.) JOHNSTON, Iowa (AP) — A tornado briefly touched down Monday evening in the Des Moines suburb of Johnston, uprooting trees and damaging traffic signals. The National Weather Service confirmed the tornado (rated an EF-1). The twister in the Johnston area packed winds of up to 95 miles per hour, tracked for 1.6-miles, and was a maximum of 50-yards wide. It began at around 6:26-p.m. and ended three minutes later. No injuries were reported.
In eastern Iowa, winds gusted up to 67 mph in Newton, and high winds Monday night near Luxemburg lifted the roof off a barn and crashed it into another building, causing it to collapse onto a hog nursery building. The Dubuque Telegraph Herald reports the nursery building then caught on fire, killing 300 hogs inside.
The Weather Service said more severe weather is expected today (Tuesday), with thunderstorms, heavy rain and a chance of tornadoes. The rain could lead to localized flooding.
(Updated timing and area coverage 8:20-a.m.) The National Weather Service reports a round of showers and storms will pass over Iowa this morning. Another round of strong to severe storms will move across Iowa this afternoon and early evening. The storms this afternoon may produce tornadoes that develop rather quickly as well as damaging thunderstorm winds and also the potential for locally heavy rainfall. Be mindful of the severe weather potential today and be prepared to act very quickly if severe weather threatens your area.
