On Wednesday.....there is HIGH RISK for southern GA and northern FL.....Moderate Risk for northeast GA, western and central SC, and south-central and western NC. Deposition will take place Wednesday or Wednesday night. On Thursday....there is Strongly Moderate Risk for growers in northern FL, southern and eastern GA, and southern SC.
