A strong pressure gradient between high pressure well to the north and hurricanes well east and well west of Florida resulted in several days of strong and gusty onshore flow. The long fetch of onshore winds also directed large northeast swells to the east-central Florida coast. In addition, large easterly swells associated with major Hurricane Teddy located near Bermuda propagated to the coast. These conditions combined to produce water levels 1.5 to 2.0 feet above predicted astonomical tides during 5-6 high tide cycles. Water levels measured at the Trident Pier CMAN at Port Canaveral peaked at 6.6 feet MLLW around 1000LST on September 20 and again around 1030LST on September 21. Minor to locally moderate coastal flooding occurred along several beachfront locations, mainly near high tide. Minor to moderate beach erosion was common along much of the coastline, with some areas of major erosion.

Minor to locally moderate coastal flooding occurred near the times of high tide. The greatest impacts were reported along portions of Daytona Beach, New Smyrna Beach and Bethune Beach. Dunes, jetties and seawalls were overwashed, with water over several beachfront roads, requiring closures. Beach erosion was primarily minor to moderate, with flattening of the beach profile and dune recession ranging from none to moderate.

Local, minor coastal flooding occurred near the times of high tide. The greatest impacts were reported along Melbourne Beach, where several county crossovers were damaged. Minor to moderate beach erosion occurred along the central and northern county beaches, with moderate to severe erosion along the south county beaches (Spessard Holland Park to Sebastian Inlet State Park). The tallest dune escarpment within this area was about 12 feet.

Minor to locally moderate beach erosion impacted the Indian River County beaches. The most significant erosion occurred at Jaycee/Conn Beach near Vero Beach, where several feet of berm lowering was observed, with one foot of dune retreat. Moderate erosion was also observed at Wabasso Beach and Tracking Station Beach.

Coastal Flood in MARTIN, FLORIDA

Minor to moderate coastal flooding occurred near the times of high tide. The greatest impacts occurred as excess sea water entered St. Lucie Inlet and raised water levels within the St. Lucie River. Water inundated many roadways and properties adjacent to and near the river, primarily within Palm City, Stuart, Sewall's Point and Port Salerno. High water levels within the Indian River caused roadway flooding in Jensen Beach, as well as roadway flooding and water intrusion into a few homes in Hobe Sound. Sea water also entered Jupiter Inlet and raised water levels within the Indian River and Loxahatchee River, causing roadway flooding in far south Jupiter Island and in Tequesta. Beach erosion was primarily minor to locally moderate.

Coastal Flood in ST. LUCIE, FLORIDA

Minor to locally moderate coastal flooding occurred near the times of high tide. The greatest impacts were reported near Ft. Pierce Inlet, where the boat launch was closed due to missing planks on a dock and some washouts nearby. In addition, the earthen berns surrounding several mosquito impoundments along both sides of the Indian River
suffered minor erosion from overwash. Beach erosion was mainly minor, except locally moderate along portions of Ft. Pierce Beach, where about 30 feet of beachfront was lost.
