The twister in Anita happened between 9:58- and 10:00-a.m. Tuesday, and was rated an EF-1 on the Fujita Scale, with wind speeds estimated at 90-mph. The tornado was on the ground for a little more than six-tenths of a mile. It was estimated to be 30-yards wide.

The tornado in Carbon took place between 9:31- and 9:33-a.m., Tuesday. It was rated an EF-0, with winds estimated at 80-mph. It traveled on the ground for about 1.75-miles, and was a maximum of 30-yards wide.

In both counties, there were no injuries or deaths resulted from the storms, but there were reports of property damage. Wednesday morning, Cass County Emergency Management Coordinator Mike Kennon said 12 homes were identified as having some minor damage, such as broken windows, siding and trim, shingles and ridge caps, as well as to garage doors. Caring Acres Nursing Home sustained some damage. Numerous trees were knocked down in the area.

April 19th, 2024 by Ric Hanson

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.

April 18th, 2024 by Ric Hanson

(Johnston, Iowa) – The National Weather Service reports three more tornadoes associated with Tuesday’s (April 16th) severe storms, have been confirmed. That includes two EF Unknowns, one near Manson with a path of just over six-tenths of a mile, the other south of Rolfe, with a path length a little more than 1.5 miles.
EF Unknows mean the wind speed is unknown since the tornado did not impact any damage indicators that are used to produce the rating. The other tornado was a EF0 near Rolfe with a path length of just slightly more than six-tenths of a mile, and an estimated wind speed of 70 mph.
According to the latest data, seven tornadoes occurred at various locations across the State, Tuesday, causing structural damage in at least two counties. The Weather Service continues to collect and analyze data about the storms.

The damage occurred at around 10-a.m., Tuesday. Kennon says 12 homes were identified as having some minor damage. Broken windows, siding and trim, shingles and ridge caps, as well as garage doors, sustained damage in some parts of Anita. Numerous trees also fell, to varying degrees.

(Updated) Storms in Iowa, Tuesday, spawned tornadoes in 4 counties

(Radio Iowa) – The National Weather Service says a minimum of four tornadoes touched down in Iowa on Tuesday, including one each in Calhoun, Dallas, Lee and Pocahontas counties. Among the damage, a barn was leveled near Dallas Center and there’s major damage to a house near Salem. National Weather Service meteorologist Kristy Carter says survey teams are fanning out this (Wednesday) morning to look over the damage at the various sites.

“Those numbers can change as we continue to get more data throughout the day today,” Carter says. “We don’t have any ratings on any of those tornadoes yet. We’ll continue to be collecting data and trying to look at satellite imagery to figure out paths and surveys.” It was initially thought that just one twister set down in north-central Iowa around 2:30 P-M, but she says there were at least two, perhaps more, that emerged from that single storm cell.

“There were a couple of tornadoes that happened in Calhoun and Pocahontas. They weren’t necessarily all continuous, so at least at the moment, we’re thinking there are multiple tornadoes,” Carter says. “That’ll just be part of the data that we continue to collect here today and as we get some information about damage in the path and the survey.” There are multiple reports of large hail all over central and eastern Iowa, while winds were clocked up to 72 miles an hour in Cedar County near Stanwood. All across the state, there were reports of fallen trees and tree limbs which caused dozens of power outages.

“There were some reports of hail. We had one-to-two inches in diameter. We had plenty of wind gusts, 50-to-60 miles an hour,” Carter says. “It was really the winds that most people probably experienced, with all of our environmental wind, so outside of thunderstorms.” Funnel clouds were reported over Le Claire and near Cedar Rapids, but neither reached the ground to become tornadoes. No injuries are reported.
