Timeline of the 2012 Atlantic hurricane season

[1] The season officially began on June 1, 2012, and ended on November 30, 2012, dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin.

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.

The system moved ashore the southern coast of New Jersey as an extratropical cyclone in late October.

This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season.

Additionally, 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 products.
