532 AM CDT MON MAY 12 2014

…THE FLASH FLOOD WARNING FOR ADAIR COUNTY IS CANCELLED…

THE HEAVY RAIN HAS ENDED AND ANY FLOOD WATERS HAVE RECEDED.
THEREFORE…FLASH FLOODING NO LONGER IS EXPECTED TO POSE A THREAT TO
LIFE OR PROPERTY. HOWEVER…PLEASE CONTINUE TO HEED ANY ROAD
CLOSURES.

Damage assessment teams were scheduled to arrive in Guthrie and Dallas Counties this (Monday) morning, to try and determine whether extensive storm damage was caused by straight-line winds or a tornado.

Buildings were damaged by a storm that roared through the Lake Panorama area near Panora, in Guthrie County. Authorities say at least eight condominiums at the lake were damaged Sunday night, but no injuries were reported. One man who took shelter in a condo bathroom was found unharmed. If it’s determined a tornado resulted in the damage, the twister will be given a rating based on the Enhanced Fujita scale.

The severe thunderstorms that impacted western Iowa late Sunday evening and overnight, began Sunday afternoon in south-central Nebraska. They took about three-hours to move into the Omaha/Council Bluffs metro area, but during that time frame they brought several tornadoes, hail and heavy rain, and left thousands without power. Homes and businesses were damaged in at least four Nebraska towns. The storms also left nearly 17,000 Nebraska utility customers without electricity Sunday evening. By the time the initial storms reached Omaha, the storms still produced winds over 70 mph and heavy winds, with radar indicated but no official sightings of tornadoes.

The storms crossed into western Iowa by 7-p.m., resulted in the first warnings for severe weather in Pottawattamie and Mills Counties. As they spread across southwest and western Iowa, the storms left baseball-sized hail in Fremont County, and brought 60-mile per hour winds to an area just east of Marne. The storms also dumped rain ranging from just under 1.5-inches in Shenandoah to as much as 3.5-to 4-inches in the Avoca and Lewis areas.

The area last storm warning was for Flash Flooding in Adair County. It was issued today (Monday) at 12:30-a.m.
