In a joint statement issued Wednesday afternoon, the state's congressional representatives praised the decision.
"This is wonderful news for the families that are struggling financially after the devastating derecho hit our state," said Sen. Joe Manchin, D-W.Va.
"Many homes were damaged and lives uprooted, and I am glad that FEMA reversed its decision," said Sen. Jay Rockefeller, D-W.Va. "West Virginians can now put this difficult time behind them and move forward with their lives."
Rep. Nick Rahall, D-W.Va., said families should quickly check with FEMA to see if their storm costs are covered.
Businesses and individuals are being asked to call 1-800-621-FEMA or visit www.FEMA.gov to register requests for assistance.
Rahall said he hoped FEMA's decision to reconsider means other counties may receive aid in the future.
"I hope that it opens the door to additional aid for other individuals and families struggling to rebuild in the aftermath of the storm," he said.
Tomblin said state officials are continuing to evaluate post-storm damage assessments and may request additional consideration soon.
"We continue to evaluate the possibility of adding additional counties to the declaration, because we know how important this assistance is for many families throughout West Virginia," Tomblin said.
