Timeline of the 2012 Atlantic hurricane season

A map of the Atlantic Ocean depicting the track of 19 tropical cyclones.
Track map of all Atlantic tropical cyclones in 2012

The 2012 Atlantic hurricane season featured the third-most named storms for the third consecutive year on record.[1] Though the season officially began on June 1 and ended on November 30, dates which conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin,[2] two storms – Alberto and Beryl – developed before the official start, on May 19 and May 26, respectively; this was the first such occurrence since the 1908 season.[3] The season's final storm to form, Tony, dissipated on October 25, although the previous cyclone, Sandy, did not do so until four days later.[4][5]

The season produced nineteen tropical cyclones, all of which intensified into tropical storms; ten became hurricanes, but only two strengthened into major hurricanes.[nb 1][nb 2] Storm impact during the season was widespread and ruinous, with the most significant storms in term of loss of life and damage being hurricanes Isaac and Sandy. A Category 1 on the Saffir–Simpson hurricane wind scale, Isaac was a large system that moved ashore the coast of Louisiana on August 12; the storm resulted in 41 deaths overall.[8] Sandy, the second and final major hurricane of the season, was the largest Atlantic hurricane ever recorded, with a wind diameter of more than 1,100 mi (1,800 km). The system moved ashore the southern coast of New Jersey as an extratropical cyclone in late October. During its duration as a tropical cyclone, Sandy caused at least $68 billion (2012 USD) in damage and 285 fatalities.[9][10] Sandy is the second-costliest Atlantic hurricane in recorded history, surpassed only by Hurricane Katrina during the 2005 season.[11]

This timeline includes information that was not operationally released, meaning that data from post-storm reviews by the National Hurricane Center, such as a storm that was not operationally warned upon, has been included. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season.

Notes

  1. An average season, as defined by the National Oceanic and Atmospheric Administration, has twelve tropical storms, six hurricanes and two major hurricanes.[6]
  2. A major hurricane is a storm that ranks as Category 3 or higher on the Saffir-Simpson hurricane wind scale.[7]
  3. The figures for maximum sustained winds and position estimates are rounded to the nearest 5 units (knots, miles, or kilometers), following the convention used in the National Hurricane Center's operational products for each storm.[13] All other units are rounded to the nearest digit.
