Officials with the Shelby County Emergency Management Agency are requesting participating businesses and fire departments in the County, to place their local “Fire Danger” indicator signs in the EXTREME category, now through Thursday.
The western half of Iowa is under a Red Flag Warning this afternoon, and officials say they expect the same dangerous conditions to be present for the next days. High wind and low humidity will cause any fires that start to quickly grow out of control.
Extreme conditions mean, absolutely no outdoor burning. Permits need to be completed and signed by a Fire Chief before any controlled burns are executed during extreme conditions. There is a chance of rain Wednesday afternoon, and a better chance Wednesday night, but until rain puts a dent in the dangerous conditions, outdoor burning is prohibited.

Weather experts have been spending this past week preparing Iowans for springtime threats such as tornadoes, hail and lightning. National Weather Service meteorologist Todd Heitkamp is also trying to dispel the many myths associated with severe weather. For instance, lightning can strike twice in the same spot. “There’s no doubt that’s a myth,” Heitkamp says. “Lightning can strike as often as it wants to and more often than not, lightning will strike the same place multiple times.”
Some Iowans might believe it’s a good idea to open windows and seek shelter in the southwest corner of a home in event of a tornado. That’s not the best advice, according to Heitkamp.”We want people to seek shelter underneath something sturdy or in a small, interior room. Stay out of the corners because the corners are actually the worst possible places to be during a tornado,” Heitkamp says.
“Opening the windows — it makes no difference. If the tornado wants the windows open, believe me, it is going to open them whether you like it or not. You better utilize that time to get yourself and your family members to your place of safety.” Another common falsehood about tornadoes is they’ll never cross a body of water.
“Nothing stops a tornado other than the tornado itself,” Heitkamp says. “Tornadoes can cross bodies of water — lakes, rivers and streams.” Heitkamp says knowing the difference between weather myths and weather facts may help save your life. The past week was designated as Severe Weather Awareness Week.
