JACKSONVILLE, Fla -- Tropical storm "Debby" will continue to spin bands of heavy rain and thunderstorms northward across metro Jacksonville, Northeast Florida and Southeast Georgia through at least Wednesday. Additional rainfall should average 2-5" but local amounts of 10"+ will be possible where banding persists for an extended period of time. With the ground already saturated, flooding will continue to be a major threat. Isolated tornadoes will also be possible through Tuesday and even into Wednesday.

The St. Mary's River at Macclenny is forecast to crest at 14.9 feet which will cause minor flooding (flood stage 12 feet). The Suwannee River in Columbia County will crest Thursday morning at 79.3 feet just above flood stage 77.0 feet. Keep in mind that water levels and forecast crests could vary a great deal depending on additional rainfall.
