PANORA, Iowa (AP) — Preliminary data shows an EF-2 tornado touched down in central Iowa during severe weather that hit swaths of the state. The National Weather Service says a line of thunderstorms produced at least one tornado Sunday night that hit the community surrounding Lake Panorama in Panora. Officials are still surveying damage to determine if other tornadoes were recorded.

The tornado reached 115 mph and was first recorded south of Guthrie Center before it traveled more than 16 miles northeast. It went across Lake Panorama and dissipated near Yale. Officials in Lake Panorama say the tornado destroyed eight condominiums and damaged about a dozen other homes. No injuries were reported.

More severe weather was expected in Iowa later Monday, with thunderstorms and potential flash flooding.

DES MOINES, Iowa (AP) – Forecasters say much of central and eastern Iowa could be affected by another wave of severe weather moving across the state.  The National Weather Service says a system expected to cross central Iowa early Monday evening could cause large hail, damaging winds and tornadoes.

Meteorologist Kurt Kotenberg says the eastern third of the state is at greatest risk, especially parts of southeast Iowa. However, he says the storm shouldn’t be as powerful as the one that moved through Iowa on Sunday night. He says large hail is the primary concern.

Sunday’s storms damaged buildings near Panora.

ADAIR IA-
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.
