Hurricane Ignacio was the latest-forming first hurricane of a Pacific hurricane season since reliable satellite observation began in 1966. The ninth tropical storm of the 2003 Pacific hurricane season, Ignacio developed out of a tropical wave on August 22 a short distance off the coast of Mexico. It was initially predicted to track out to sea and remain a weak tropical storm, though it unexpectedly organized rapidly to attain peak winds of 105 mph (165 km/h) on August 24 while located a short distance southeast of southern Baja California Sur. Land interaction weakened Ignacio to an 80 mph (130 km/h) hurricane by the time it made landfall near La Paz, and it dissipated on August 27 in the central Baja California peninsula.
