It later struck the mainland of northwestern Mexico as a tropical storm, and its remnants generated severe thunderstorms and intense flooding in portions of the Southwestern United States.
[9] Hurricane Iselle in early August was the strongest recorded tropical cyclone to make landfall on Hawaii's Big Island; torrential rainfall of up to 15.25 in (38.74 cm) caused significant flooding, with damage exacerbated by strong winds.
[3] Marie's large size and immense strength produced high surf that drowned four people in the United States and Mexico; damages totaled US$20 million in the former country,[11] while flooding from peripheral rains in the latter caused two additional fatalities.
Figures for maximum sustained winds and position estimates are rounded to the nearest five units (knots, miles, or kilometers) and averaged over one minute, following National Hurricane Center practice.
This timeline documents the formation of tropical cyclones as well as the strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season.
