Isis first affected Baja California Sur on September 2 as a tropical storm. Shortly after making landfall, a weather reporting station at San José del Cabo recorded sustained winds of 26 mph (42 km/h), and gusts reaching up to 46 mph (74 km/h). A station on the Islas Marías also reported sustained winds of 54 mph (87 km/h). The winds left widespread areas without power or telephone. The storm produced heavy rainfall in the southern portion of the peninsula, including a 24‑hour total of 12.99 inches (330 mm) at Los Cabos and a peak rainfall total of 24.02 inches (610 mm) at Santiago. A married couple was killed after attempting to cross a flooded stream in Los Cabos. Initially, reports indicated a family was missing in La Paz, though they were later proven false. Flooding from the storm closed all roads to the north of Los Cabos and caused damage to the roads in the area. Mudslides from the rain buried at least 120 cars in the area.
