Sinkholes have warning signs

Warning signs

Experts say there's really nothing anyone can do to prepare for a sinkhole like the one Thursday night in Seffner. But there are warning signs:

• Gradual localized ground settlement

• Doors and windows failing to close properly

• Cracks in a foundation or steps

• A circular pattern of ground cracks outlining the sinking area

• Cloudiness in local well water due to sediment washing into the limestone's pores
