Michigan Gov. Rick Snyder said Tuesday it was appropriate to consider federal help to respond to widespread flooding in the state.

A lingering weather pattern dumped several inches of rain on much of the lower peninsula Monday and into Tuesday. The governor toured the area by helicopter and said Tuesday he was reviewing his options for recovery.

Emergency authorities, he said, were considering federal options.

"As appropriate, we'll look at the declarations that follow [a review]," the governor said from Detroit.

Michigan State Police are calling on authorities to avoid flooded streets in the area, which have left at least one person dead.

Snyder says people may see signs of a clear road ahead, or otherwise try to get around barriers, but advised against it in flooded areas.

"Don't. Please don't," he said.
