Cedar River Flooding
Todd Shea, Warning Coordination Meteorologist
Rainfall maps
Nearly every creek...stream and river in Chickasaw and Floyd Counties was bankfull or flooding. Many roads were impassable. There was extensive evidence of flash flooding from heavy rains that fell last night.
On the Cedar river...approx. 100 homes in Charles City had some type of flood damage. Only the Main street bridge was passable and flood waters had crossed on to sections of highway 218 closing businesses. The river level was so high...it peaked the river gauge there but had started to slowly fall as of early afternoon.
Downstream in Nashua...water had topped the dam at Cedar lake flooding nearby homes. Some water was crossing highway 346 but had backed up along the train bridge there allowing water to rise into the downtown area. Sand bagging efforts were in full swing as the river crested.
Sections of the Wapsipinicon and little Wapsipinicon rivers were nearly a mile wide flooding nearby fields and closing sections of highway 18...346 and 63.

Nashau IA tornado - F1
Todd Shea, Warning Coordination Meteorologist
Picture of the tornado track.
Wind damage was first observed along highway 218 about 3 miles northwest of Nashua in southeast Floyd county. Large trees and sections of a barn were blown in primarily one direction...but there was no evidence of a touchdown in nearby corn fields. This apparently was microburst wind damage as the tornado was forming.
A tornado did touchdown about 3 miles north of Nashua...near The Floyd-Chickasaw county line and crossed county road T76 before dissipating some 400 yards to the northeast. Two farms had extensive damage including a blown down silo...several damaged barns and outbuildings...sheared trees...damaged crops and downed utility poles. A convergent pattern was apparent in the corn fields.
The tornado was rated an F1 and had a length of approx. 2 miles. The greatest width was about 80 yards. Witnesses said the tornado hit about 530 pm. The power did go off at the second farm right at 530 pm and they did hear outdoor warning sirens from Nashua. There were no injuries or deaths.
