ATLANTA (AP) — Most of Georgia will be under a flood watch as forecasters predict that showers and storms will wash out many Fourth of July activities.

The National Weather Service said the storms hold the potential for significant flash flooding and river flooding Wednesday through Friday. The storms are expected to gradually spread over the state through Wednesday and should gradually end on Friday.

Rainfall from the storms is expected to range from 2 to 4 inches.

In metro Atlanta, a flood warning has been issued for Big Creek in the Alpharetta area, where forecasters were predicting that heavy rainfall will cause significant runoff into streams and rivers and cause flooding in some areas.
