US President Barack Obama declared three West Virginia counties federal disaster areas Saturday after devastating floods killed at least 24 people, FOX News reported on Sunday. 

In addition to those confirmed dead, state officials believe an unknown number of people are missing in Greenbrier County, where 16 people were confirmed dead.

"It does not appear there are unaccounted for people in other counties, but it's still a somewhat fluid situation," said Chris Stadelman, Tomblin's chief of staff.

Kanawha and Nicholas counties were also approved for individual assistance, which includes housing and crisis counseling.

Gov. Earl Ray Tomblin was expected to add between six and eight more counties to a formal application for federal disaster aid, which is expected to be filed within the next week.
