Hurricane Olaf continued to intensify and reached peak intensity while its center was just offshore the southwestern coast of Baja California Sur, with maximum sustained winds of 105 mph (169 km/h) and a minimum barometric pressure of 975 mbar (28.8 inHg).

Severe rainfall, flooding, mudslides, uprooted trees and damage to power lines and hotels affected the state as the hurricane made landfall and moved over the peninsula.

[1][5] Olaf intensified at an even quicker rate as it neared to southwestern coast of the Baja California Peninsula, developing a symmetrical eyewall as its winds increased by 20 mph in just six hours.

[6] At 02:50 UTC on September 10, Olaf reached peak intensity with maximum sustained winds of 105 mph (169 km/h) and a minimum barometric pressure of 968 millibars (28.6 inHg); the storm made landfall very near San José del Cabo at this time.

[9] Shortly after emerging back over water, the organization of Olaf collapsed, including its eye and eyewall, and it was downgraded to a tropical storm by 12:00 UTC.

[1][10] Gradually moving westward away from land, Olaf continued to rapidly weaken, with its low-level center becoming exposed and devoid of any deep convection by 21:00 UTC.

[11] By 06:00 UTC on September 11, Olaf had been devoid of any organized deep convection for 12 hours, and was therefore designated a remnant low as it turned back to the southwest.

[17] Up to 6 in (150 mm) of rainfall was anticipated for the states of Baja California Sur, Sinaloa, and Nayarit as Olaf approached, along with potential surf of up to 23 ft (7.0 m).

[23] Moisture associated with Olaf resulted in heavy rains and flash flooding across the state of Jalisco, causing the collapse of a trailer near Mexican Federal Highway 80 and an associated fatality.

[24] Heavy rains from both Olaf and Hurricane Nora, which affected northwestern Mexico less than two weeks prior, prompted the closure of beaches across the neighboring state of Nayarit.
