What the reports say
Written by National Weather Service staff at the time of the event · public domain
Rainfall coupled with rapid melting of low elevation snowpack on top of frozen and saturated soil led to widespread flooding. Many county roads and large sections of agricultural land were flooded. County Road 1100 East was washed out at the Deep Creek crossing and many other roads were closed and severely damaged. Snow and ice filled canals caused water to overflow canal banks and contribute to the flooding.
The Twin Falls County Sheriff's office reported strong winds associated with a thunderstorm 5 miles south of Kimberly, Idaho. Kimberly is in south central Idaho 5 miles southeast of Twin Falls. The most costly damage was done to two center- pivot irrigation systems. Other damage included roofing torn free from buildings, around 20 trees uprooted, a windmill blown over, and a car damaged by a small falling light pole. Also, a pickup RV camper was rolled over. A farmer reported a missing calf. The wind was strong enough to pick up a 300-pound door and carry it across a street.
