DELTONA, Fla. -

Workers at Deltona High School are dealing with a big problem after a hole opened beneath a building.

A spokeswoman for the district said it's believed the hold started to form about two weeks ago. However, because it's under the building, officials are not sure how big the hole is.

The building has been fenced off while crews try to figure out how to fix the problem.

Officials said they hope the problem is solved by the time students return in mid-August.
