DES MOINES, Iowa [KCCI/NWS]— The National Weather Service determined at least five tornadoes touched down Tuesday afternoon (April 16,2024) in Calhoun and Pocahontas counties. All five twisters came from the same thunderstorm that traveled through that area of northwest Iowa. The strongest was an EF-1 that tracked just east of Rockwell City.

• The storm dropped its first tornado southeast of Rockwell City at 2:26 p.m.
• The second tornado touched down just south of Manson at 2:57 p.m. This tornado was rated EF-Unknown because it didn’t damage anything that could be used to estimate wind speed.
• The third tornado touched down east of Palmer in Pocahontas County at 3:11 p.m.
• The storm’s fourth tornado spun up northwest of Gilmore City at 3:34 p.m.
• Still moving across eastern Pocahontas County, the storm produced its fifth tornado on the edge of Rolfe at 3:42 p.m.

Those tornadoes are in addition to the EF-0 that spun up in Dallas County, two others in eastern Iowa, and at least four between Sioux City and Sioux Center, for a total of a dozen twisters.

More tornadoes from Tuesday could still be confirmed.
