Tornado threat remains after four injured and hundreds of homes damaged

The multi-day tornado outbreak continues Saturday, with powerful storms expected from Texas to the Great Lakes.

A tornado warning is in effect for parts of six states from Texas to Iowa until late this evening. This watch will likely move slightly to the east during the day.

A moderate risk — level 4 out of 5 — is expected for parts of Texas, Oklahoma, Kansas and Missouri on Saturday, with storms expected to flare up again across much of the country in the afternoon and evening. There is a chance of strong tornadoes over long distances, but also of very large hail with a diameter of up to 7.5 cm and thunderstorms up to 130 km/h.

In addition to dozens of tornado reports, there were 33 damaging wind reports and 60 large hail reports on Friday.

In Iowa, four people were injured and about 120 structures damaged Friday after severe weather hit Pottawattamie County, officials in that county said.

The city of Minden was the hardest hit area during Friday’s storms, according to the province. Gas and electricity supplies have been cut and a 10 p.m. curfew has been imposed until further notice.

Gov. Kim Reynolds, Pottawattamie County and the city of Minden have all declared states of emergency.

Severe damage was also reported in eastern Nebraska, including Douglas County, where hundreds of homes in the Omaha area were damaged Friday.

Preliminary information suggests two “strong, rare tornadoes” touched down in Douglas County, Chris Franks of the National Weather Service said at a news conference Saturday. The National Weather Service found evidence there of damage from tornadoes EF-2 and EF-3 after Friday’s storms, Franks said.

So far, no fatalities have been reported as a result of the storms, officials said.

“For such a large storm, to have the property damage that was so extensive, without any loss of life,” Douglas County Emergency Management Paul Johnson said at the news conference. “It’s a great asset for the city of Omaha.”

Nebraska Governor Jim Pillen urged people to stay safe as the storm threat continues into Saturday evening.

So far there have been seven tornado reports on Saturday. One tornado emergency was issued for Knox City, Texas, where a large and damaging tornado was reported near the city. Baseball-sized hail was also reported in this tornadic storm.

A tornado was confirmed Saturday near the intersection of Kansas, Nebraska and Missouri. The confirmed tornado was located eight miles north of Robinson, Kansas.

All forms of severe weather are likely on Saturday.

Damaging winds, huge hail and long-range tornadoes are all on the cards, especially in Kansas, Oklahoma and northeast Texas. Overall, a severe weather threat exists across the central US from Canada to Mexico.

The threat of these dangerous storms will continue into the overnight hours.

In addition to the thunderstorm threat, there is also a risk of flooding with this severe storm system.

Eight states from Texas to Iowa are under a flood watch until Monday afternoon. This is because heavy rainstorms can dump significant rainfall in a short period of time and lead to dangerous flash flooding.

More than 2 to 3 inches of rain could fall in a short period of time, prompting the Weather Prediction Center to issue a moderate risk for excessive rainfall from Texas to Missouri.

“Confidence remains high in a major flash flood developing for portions of east-central Oklahoma, with higher precipitation totals late Saturday evening into Saturday evening,” the Weather Prediction Center said.

A “high risk” for excessive rainfall is the biggest possible threat. A third of all flood-related deaths occur in high-risk areas. It is a rare and serious life-threatening flooding event that leads to a high-risk problem.

The National Weather Service will conduct damage surveys this weekend to determine the number of confirmed tornadoes, intensity ratings and other details.

On Sunday the threat is reduced, but there is still a chance of damaging winds, large hail and a few tornadoes from Austin, Texas, to Davenport, Iowa, and includes Shreveport, Louisiana; Little Rock, Arkansas; Kansas City and St. Louis, Missouri.
