Heavy rain in north central Iowa this afternoon fell in the Cedar River basin. The 4-6″ of rain is enough for the river to rise pretty quickly and above flood stage. The image below shows where the radar estimates the heaviest rain to have fallen. Click here for the Cedar River forecast. If you want to see other rivers…there is a button on the right side of the blog that says “River Levels”.
Here are some rain totals I have found in eastern Iowa:
Charles City: 2.18
West Union: 1.63
Harpers Ferry: 0.46
Waterloo (KWWL): 0.17
Cedar Falls: 0.15
Waterloo (Airport): 0.09

Here is in Iowa, we know all too well what it is like to have water close roads, homes and business under water and farm land turned into a river. The Missouri River has been causing major flooding for a while and will for most of the summer. Here are some photos that show how bad it really is. Click on the photo to see many more photos.
