PINELLAS COUNTY, Fla.- Firefighters are on the scene of another possible sinkhole underneath a home in Pinellas County.

Initial reports say there's extensive cracking both inside and outside the house. Everyone inside has been evacuated. There is no word of any injuries.

As a precaution, two neighboring homes are also evacuated.

If this is confirmed to be another sinkhole, it would be the third major ground collapse in the Tampa Bay area this week. Two others have opened in Seffner, including one that killed a man who was asleep in his bedroom at the time.
