1964 Atlantic hurricane season
Approaching the east coast of Florida, Dora's motion became erratic, making a few cyclonic loops. Around 04:00 UTC on September 10, the hurricane made landfall near St. Augustine, Florida, with winds of . Two hours later, Dora weakened to a Category 2 hurricane. However, deterioration then slowed, with the hurricane falling to tropical storm intensity on September 11. Dora then briefly drifted over southwestern Georgia, until turned east-northeastward late the next day. Early on September 14, the storm re-emerged into the Atlantic Ocean near Cape Hatteras, North Carolina, and became extratropical several hours later. The remnants of Dora moved rapidly northeastward and dissipated offshore Newfoundland early on September 16.
Tropical Storm Doria
In New Jersey, Doria produced wind gusts of up to 54 mph (87 km/h) and storm tides 5.3 feet (1.6 m) above normal in Atlantic City. The outer bands of the storm spawned an F2 tornado near Cape May. It moved quickly northward through Cape May County, and caused about $250,000 in damage (1971 USD, $  USD) in damage along its 29-mile (47 km) path. The storm dropped heavy rainfall, peaking at 10.29 inches (261 mm) in Little Falls. Record 24-hour rainfall totals occurred in Newark with 7.84 inches (199 mm) and Trenton with 7.55 inches (192 mm). The rainfall led to record flooding on several small streams in the state. The Beden Brook crested at over 5 feet (1.5 m) above normal, which destroyed a bridge near Princeton. The Raritan River at Manville crested at 9.8 feet (3 m), a record that stood until the passage of Hurricane Floyd in 1999. The heavy rainfall overtopped the levee system in Zarephath, causing severe damage to the Alma White College and preventing it from opening in the fall of 1971. The rainfall also flooded two fire houses in Somerville with several feet of water, and the water treatment plant in Bridgewater Township with 18 inches (457 mm) of floodwaters in what was catalogued as a 50-year flood event. Following the flooding to the water treatment plant, officials raised the beams of the plant to withstand a 500-year flood event. Eleven houses experienced flooding damage in Montgomery Township. Doria killed three people and caused $138 million in damage (1971 USD) in the state.
