Heavy Rain in Flagler County, Florida

Storm total rainfall ranged from 3.5 to 6.25 inches across Flagler county from 12/16 through 12/17.

A strong surface low deepened across the eastern Gulf of Mexico as high pressure dominated northeast of the region creating very strong onshore flow. Several days of persistent onshore flow increased water levels along the local Atlantic coast and within inland estuaries including the St. Johns River basin. As the low crossed the state, strong winds, heavy rainfall and storm surge impacted NE Florida and SE Georgia Saturday night 12/16 into Sunday 12/17. Wind gusts increased to 40-50 mph overnight and continued to remain strong into Sunday afternoon with gusts increasing to 45-56 mph as the low departed NE of the region with strong post-frontal pressure rises and drier air enabling strong low-level winds to mix down to the surface.
