Kansas Gov. Sam Brownback says residents took storm warnings seriously as heavy storms and dozens of tornadoes battered the state, causing extensive damage but no fatalities.

The tornadoes that touched down across the state Saturday and early Sunday hit Sedgwick and Rice counties especially hard. A reported tornado in Wichita caused damage at McConnell Air Force Base and at a Wichita mobile home park. Preliminary damage estimates could be as high as $283 million.

Brownback, who issued a declaration of disaster emergency early Sunday, said the state was fortunate to have escaped fatalities. He says residents responded to the storm warnings and took cover, and that preparation may have saved many lives.

The National Weather Service says conditions Sunday called for high winds, but no major storms in Kansas.
