(UPDATE 2:20 p.m.) The Walmart fire is now out. There appears to be a hole in the roof where flames and smoke were coming out.
The Walmart on Roosevelt Boulevard in Largo is evacuated and closed while crews battle a large roof fire.
No one has been injured.
There is no word on the cause of the blaze.
The store, near U.S. 19 and East Bay Drive, just opened two and a half years ago.
