Officials with the National Weather Service today (Wednesday), confirmed a weak tornado with wind speeds estimated at 70-miles per hour, caused damage to standing corn, but no structural damage. In their preliminary assessment, officials said the twister was rated an EF-0, which typically have winds of 65-to 85-mph. The Guthrie County twister started at around 6:20-p.m. Tuesday about four-miles southwest of Jamaica, and ended one-half mile south of Jamaica about 12 minutes later. It was four miles long and 80-feet wide. It tracked northeastward through primarily cropland, causing tracks where it flattened the corn in a distinct path.

An EF-1 tornado in Clarke County packed winds estimated at 100-to 110-mph. It was generated at around 7:48-p.m. and ended at around 8:02-p.m. The twister was 250-feet wide at the height of the storm, and was on the ground for about seven-miles. The twister formed about four-miles north of Woodburn in an area of standing corn and ended seven-miles north/northeast of there. It crossed a road and caused damage to trees and later, two farmsteads. The winds were so powerful, they picked up several large feeding troughs and sent at least one hurtling one-quarter of a mile away. An abandoned outbuilding was damaged during the event, and a large tree was uprooted before it fell onto a mobile home, resulting in one injury.
