According to numbers released Wednesday by Nebraska Gov. Dave Heineman, at least 60 of Nebraska's 93 counties have been hit by serious storms since May 22nd. Damage to public infrastructure is estimated in excess of $20 million.

“I’ve spoken with Nebraska Emergency Management officials and we hope to have assessments for most of the damage that’s occurred so far in Nebraska by the end of the week," the governor was quoted as saying.

"However, given the potential for more storms today, we may have additional work to do. It’s important to include all eligible damage in our report, but we expect to submit a request for a federal disaster declaration soon.”

Nebraska Emergency Management Agency has been working with federal teams to compile damage assessments during the past few weeks. The estimates on infrastructure losses cover things like utilities, bridges and roads.

Estimates on damage to private homes and businesses are not yet available, but emergency management officials have determined that at least 36 homes throughout the state have been destroyed. An additional 95 residences suffered major structural damage, with 293 homes receiving minor damage.

Agents with the Emergency Management Agency spent two days in Millard sizing up tornado damage before moving on to other parts of the state. Three teams planned to visit Seward, where they had flooding damage, as well as Kearney and Polk County, which had tornado damage and high winds.

A FEMA spokesperson says they hope to wrap up their assessments throughout the state by the end of the week. That would include a total of 61 counties.

Those reports will be included when Gov. Heineman asks President Bush for a federal disaster declaration.

While many Nebraskans and Iowans are already dealing with storm damage and flooded roads, fields, yards and basements, more severe storms are possible Wednesday night and into Thursday.

Flash flood watches and flood warnings have been issued across much of the region.

Lowland flooding continued Wednesday at several spots in eastern Nebraska. In Platte County, the Monroe blacktop highway remained closed because of flooding from Prairie Creek.

The Missouri River continued to swell up and over its banks in some places. The river was three feet over flood stage of 18 feet at Nebraska City but, barring more heavy rain, was expected to fall below flood stage by Saturday.

Farther south near Rulo, the river was nearly seven feet over flood stage of 17 feet. Flood warnings were canceled Wednesday for the Big Blue River in Butler and Seward counties.
