After moving into the warm ocean temperatures of the Gulf of California, however, Lorena re-strengthened into a hurricane, and reached its peak intensity with 1-minute sustained winds of 85 mph (137 km/h) and a minimum barometric pressure of 985 millibars (29.1 inHg) Lorena made a second landfall in the Mexican state of Baja California Sur, and quickly weakened thereafter.

On the Baja California Peninsula, dangerous surf caused a man to die attempting to save his child after being pulled out to sea.

787 people were evacuated from the Eastern coastline of the peninsula to 17 temporary sheltering facilities, while numerous flights in and out of Baja California Sur were cancelled.

After weakening in the Gulf of California and leaving 2 fishermen missing, Lorena moved inland into mainland Mexico and eventually the United States.

Lorena's remnant low spawned 3 tornadoes in Arizona and caused very high rainfall totals for the region with over half a foot in some areas.

[1] At 15:00 UTC on September 11, the National Hurricane Center (NHC) noted the possibility of a low-pressure region forming within the wave off of the Central American coast.

[1] Because the storm emerged over the typically warm sea-surface temperatures of the Gulf of California, Lorena regained hurricane status and peaked with 1-minute sustained winds of 85 mph (137 km/h) and a pressure of 985 mbar (29.1 inHg) by 18:00 UTC on September 20.

[1] Lorena slowed to a crawl paralleling the coast of the Baja California Peninsula, but eventually made landfall near La Ventana at 03:00 UTC on 21 September, whilse slightly weakening below its peak strength.

[19] Governor of Colima, José Ignacio Peralta, stated on September 20 that nearly 8 inches of rain fell over the course of 24 hours during Lorena, and more than 7,400 acres of crops such as bananas and papayas were damaged statewide.

[20] Further evaluation 3 days later showed seven months worth or 1,600 hectares of bananas, papayas, lemons, and cereal crops were destroyed by Lorena in Colima.

[22] The cities Tecomán, Manzanillo, Villa de Álvarez, and Coquimatlán all had lost power due to Lorena according to the State Civil Protection Unit.

[23] An overflow of the Armería River entirely cut off parts of Coquimatlán from traffic, while several landslides in Minatitlán blocked a road.

[32] The National Civil Protection Coordination declared a state of emergency in La Paz and Los Cabos, Baja California Sur on September 22.

[34] Up to 125 mm (4.9 in) of rain fell near Los Cabos, although flooding was minimal at most due to the hurricane's small size at the time.

[43][44][24] The remnants of Lorena passed through Arizona on September 22–24, causing widespread severe thunderstorms and resulting flash floods.

[50] A very rare phenomenon for the state also occurred when an EF-1 tornado formed in Willcox, snapping power lines, injuring 2 people, damaging a barn, and tossing over mobile homes.

[49] Locals north of downtown Phoenix and in Paradise Valley reported penny- to nickel-sized hail while visibility was down to less than a ¼ mile.

[54] The Chapter of the American Red Cross in Southern Arizona was deployed and brought aid as needed for effected homes and to assess damage, especially for the Willcox tornado.
