The 1974 Atlantic hurricane season featured Hurricane Fifi, the deadliest Atlantic tropical cyclone since the 1900 Galveston hurricane. The season officially began on June 1 and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The first system, a tropical depression, developed over the Bay of Campeche on June 22 and dissipated by June 26. The season had near average activity, with eleven total storms forming, of which four became hurricanes. Two of those four became major hurricanes, which are Category 3 or higher on the Saffir–Simpson scale.
