Strong surface high pressure positioned across the mid-Atlantic region while low pressure developed near the Bahamas and retrograded across the Florida Straits, then tracked northward up the Florida east coast...and drifted inland across northeast Florida on the 10th. In the upper levels, a low retrograded over the Gulf of Mexico,which focused a plume of higher precipitable water amounts across the forecast area. A very tight surface pressure gradient produced strong wind gusts across the coastal waters and over the coastal counties for several days. Wind gusts of 40 to 55 mph were common in shower activity on the 7th and 8th, then by the 9th and 10th, gusts of 50 to 60 mph were common in just shower squalls. Thunderstorm activity increased across the area from the Atlantic during the night of the 9th and into the 10th as strong low pressure moved west across Florida from near Cape Canaveral. There was one confirmed tornado on Fleming Island in Clay County during the pre-dawn hours of the 10th. Strong onshore flow produced rough surf and large breakers with maximum breaker heights of 10 feet reported on the 9th along the St. Johns county coast.
