The National Weather Service in its mid-morning weather briefing, Saturday, said severe weather is still in the forecast for tonight across portions of Iowa. The primary threat in western Iowa appears to be from damaging winds in excess of 58-miles per hour. However, large hail and isolated tornadoes are also possible.The area is under a “Moderate risk” for severe weather.

Areas in red are under a “Moderate” risk of severe weather tonight, areas in yellow will experience a “Slight” risk for severe weather. (NWS graphic)

Keep in mind, that winds of 60-to 80-miles per hour can have the same effect as an EF-1 tornado, and tree debris may be difficult to see on the road at night.

If you are camping or have plans to do so, make sure you have a way to receive weather information and a safe place for emergency shelter, and if at home, keep your weather radio ready to go with fresh batteries.
