PRECAUTIONARY/PREPAREDNESS ACTIONS…
A FLASH FLOOD WATCH MEANS THAT CONDITIONS MAY DEVELOP THAT LEAD TO FLASH FLOODING. FLASH FLOODING IS A VERY DANGEROUS SITUATION. YOU SHOULD MONITOR LATER FORECASTS AND BE PREPARED TO TAKE ACTION SHOULD FLASH FLOOD WARNINGS BE ISSUED.
Officials with the National Weather Service say they are forecasting severe weather and flash flooding to become major threats to much of Iowa this upcoming Tuesday evening into Wednesday morning.
The latest forecast from the Storm Prediction Center shows the main threat for severe weather across the U.S. Tuesday will be across Iowa — mainly from Interstate 80 south. Heavy rainfall is expected with these storms. At this point, it shows a more than 45 percent probability of severe weather with the main threats of large hail, tornadoes and widespread damaging winds.
A combination of a much higher than usual amount of available moisture plus very strong wind shear will lead to a strong potential for severe thunderstorms. The storms are likely to move into western Iowa by around midnight, Tuesday. Tornadoes may occur during the overnight hours, so make sure you have a way to receive warning information near your bed before going to sleep.
Several inches of rainfall are also possible by and during the Wednesday morning commute. This could lead to flash flooding in flood-prone areas. Additionally, the Des Moines metro is expected to be impacted by this rainfall, so plan for extra travel time during the Wednesday morning commute.

WESLEY, Iowa (AP) – Heavy rain fell on parts of north-central Iowa Sunday and several tornadoes were reported as storms moved across the mostly rural part of the state. The National Weather Service says tornadoes were reported in Kossuth, Worth and Cerro Gordo counties Sunday afternoon, but there wasn’t any damage reported immediately from those tornadoes. The storms dumped more than 4 inches of rain on Kossuth County over a three-hour period Sunday.
That heavy rain prompted the weather service to issue flash flood warnings for Kossuth County and several other areas of northern Iowa. Forecasters warn that western and central Iowa may see severe thunderstorms Sunday evening and overnight into Monday.
