Four additional tornadoes were recorded from the tornado outbreak in Iowa on Saturday, March 5.

The recent tornado outbreak in Iowa state, especially near Des Moines area, killed seven people, including four individuals from the same family.

It is the deadliest tornado outbreak in Iowa in recent years.

The tornadoes occurred during the development of a new storm system in the Central US last week.

The recent tornado outbreak highlights the increasing frequency of tornadoes in the US over the past several decades.

This week, the weather forecast shows more are likely forming in the coming months.

This is based on a recent 2022 tornado forecast by meteorologists and from the Iowa tornado outbreak. They can occur inevitably.

Tornadoes, also called twisters and whirlwinds, can occur at any time. These natural phenomena have been characterized by their strong winds from the circling vortex of air.

The intensity of tornadoes is measured based on the Enhanced Fujita scale or EF scale, as per the National Weather Service.

Four more tornadoes have been added to the list of tornadoes that occurred last weekend. The recent addition has increased the total number of tornadoes on the list to 13, according to the NWS, as cited by the Des Moines Register.

The latest updates below show the intensity, area, and casualties caused by the four additional tornadoes in Iowa on March 5.

The tornadoes vary in intensity from 0 to 5 under the EF scale:

  •  An EF3 tornado at the Red Haw State Park in Chariton, Lucas County, killed one person.
  •  An unspecified tornado was recorded in the city of Corning in Quincy Township, Adams County.
  •  An EF0 tornado occurred in the city of Cromwell in Union County.
