Q: Passage: Jacksonville has suffered less damage from hurricanes than most other east coast cities, although the threat does exist for a direct hit by a major hurricane. The city has only received one direct hit from a hurricane since 1871; however, Jacksonville has experienced hurricane or near-hurricane conditions more than a dozen times due to storms crossing the state from the Gulf of Mexico to the Atlantic Ocean, or passing to the north or south in the Atlantic and brushing past the area. The strongest effect on Jacksonville was from Hurricane Dora in 1964, the only recorded storm to hit the First Coast with sustained hurricane-force winds. The eye crossed St. Augustine with winds that had just barely diminished to 110 mph (180 km/h), making it a strong Category 2 on the Saffir-Simpson Scale. Jacksonville also suffered damage from 2008's Tropical Storm Fay which crisscrossed the state, bringing parts of Jacksonville under darkness for four days. Similarly, four years prior to this, Jacksonville was inundated by Hurricane Frances and Hurricane Jeanne, which made landfall south of the area. These tropical cyclones were the costliest indirect hits to Jacksonville. Hurricane Floyd in 1999 caused damage mainly to Jacksonville Beach. During Floyd, the Jacksonville Beach pier was severely damaged, and later demolished. The rebuilt pier was later damaged by Fay, but not destroyed. Tropical Storm Bonnie would cause minor damage in 2004, spawning a minor tornado in the process. On May 28, 2012, Jacksonville was hit by Tropical Storm Beryl, packing winds up to 70 miles per hour (113 km/h) which made landfall near Jacksonville Beach. Question: What storm had the most significant impact on Jacksonville?
A:
Hurricane Dora
