A tropical disturbance developed on September 13 while located 340 mi (550 km) southwest of Acapulco, Mexico. Moving northwest, a depression formed on September 14.[1] It took over 24 hours to reach tropical storm strength. Paralleling the coast far offshore,[2] the storm steadily intensified over 28 °C (82 °F) sea surface temperatures.[1]

Norma turned to the north, and became a minimal hurricane on September for 12 hours as an Eye became visible via infrared imagery.[2][1] Norma turned northbound and for a while it looked like Norma would move inland. However, this did not occur due to weak southwesterly flow from a cutoff low located west of Baja California Sur; the cyclone stalled[1] and then edged slightly east when it weakened back into a depression on September 19. Tropical Depression Norma dissipated a mere 93 mi (150 km) south of the Baja California Peninsula; it never made landfall.[2]

Preparations and Impact

[edit]

Prior to the remains of Hurricane Norma's arrival in the Southwestern United States, forecasters were anticipating cloudy skies over San Diego. Over the deserts and mountains near the area, there was also a possibility of heavy rainfall, though temperatures were expect to remain cool.[3] The remnants ultimately caused rainfall and thunderstorms in California on September 22 and September 23. The rainfall totaled to .70 in (18 mm) at Lindbergh Field, and .97 in (25 mm) at Lemon Grove. There were numerous power outages, small fires, some road flooding, and some property damage.[4] In Los Angeles, the storms produced unseasonable moisture, thunder, and lighting. Rain also spread into the Southern Arizona and Southern Nevada.[5] In San Degio and southern Orange County, 200,000 homes and business lost power, but the power was quickly restored.[6] Although the storm did produce heavy rain in Baja California Sur, there are no reports of damage or flooding in Baja California Sur from the storm. This is because the area the tropical cyclone stuck was sparsely populated.[1]
