Jalisco

Tropical storm watches were issued from Zihuatanejo in Guerrero to Cabo Corrientes in Jalisco on September 17 by the Mexican government, and were later upgraded to tropical storm warnings.^[1] Hurricane warnings were also issued for Manzanillo, Colima to Cabo Corrientes on September 19.^[1] During this time, Lorena was moving very close to the shorelines of the states of Colima and Jalisco, and at its first peak in strength.^[11] Red alerts, the highest level of danger alert, were issued statewide in Jalisco,^[12] and at least 240 people there were evacuated prior to the storm.^[13] Schools were shut down across most of the state due to the impending hurricane.^[14] Flooded streets, washed-out roads, landslides in 10 municipalities, and dozens of downed trees were reported.^[15] Power was knocked out in some areas. Floods up to 3 ft (0.91 m) high affected the town of Chamela in Jalisco while Mexican Federal Highway 200 was blocked by collapsed trees and floods.^[16] 3,700 hectares of basic crops such as maize, wheat, beans and other crops such as bananas, papayas, or mangoes were destroyed by Lorena in Jalisco and recovery from this loss was anticipated to take months.^[17][18] Communications were briefly cut off, while 201 homes on the coastline were destroyed.^[13] Damage in Jalisco was calculated at 17.7 million pesos (US$910,000).^[19]

Colima

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.^[18][21] Prices of bananas thus rose by over 3 pesos in the state.^[18] La Boquita Beach was one of the most hard-hit areas of Manzanillo, with roofs ripped from homes and debris from the wind-damaged structures scattered across the area.^[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] Mexico's National Water Commission reported that in one area 283 mm (11.1 in) of rain fell in Colima within a 24-hour period.^[24] Peralta later stated that three rescues of people were required but there was no apparent loss of life.^[23] Part of the Bridge of Tepalcates, a tourist destination in Manzanillo, collapsed during the hurricane, causing traffic to be shifted to a new road.^[23] An overflow of the Armería River entirely cut off parts of Coquimatlán from traffic, while several landslides in Minatitlán blocked a road.^[23] The Cuixmala River also broke its banks in the municipality of La Huerta and flooded agricultural land.^[25][26]

Baja California Peninsula

Once Lorena moved along the southwestern coast of Mexico, the government of Mexico issued a hurricane watch for the southern coast of Baja California as the storm was expected to make landfall there as a Category 1 hurricane.^[27] Red (high-danger) warnings were issued for much of southern Baja California Sur.^[28] Once Lorena moved away from the coast and started moving closer to Baja California Sur, residents started to barricade doors and windows and pull their boats from the ocean in preparation for landfall.^[29] Government officials closed down schools for 506,000 students prior to the hurricane.^[30][28] Areas off the coast were initially expected to receive 40% of the state's annual rainfall within days.^[31] As Lorena started to move parallel to the peninsula's coast, authorities in Los Cabos said that 787 people had taken refuge in 18 shelters; many tourists did not take precaution, however, and still traveled to Los Cabos.^[20] Many flights in and out of Los Cabos International Airport were canceled on September 20.^[32] The National Civil Protection Coordination declared a state of emergency in La Paz and Los Cabos, Baja California Sur on September 22.^[33] The track of the hurricane was described as highly erratic and unpredictable.^[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.^[1] However, Lorena did produce life-threatening swells on much of the Baja California Peninsula in combination with Tropical Storm Mario.^[35][36] In Los Cabos, a father and son were swept out to sea by a large wave. The father drowned while trying to save his son, who survived.^[37]

Other states

On September 18, Lorena briefly affected the states of Guerrero and Michoacán. There were reports of heavy rainfall and downed trees.^[38][39]

Residents of Sonora prepared for torrential rainfall as Lorena approached as a tropical depression on September 21.^[40] Orange and yellow alerts were issued for much of the coast of Sonora as Lorena rapidly approached.^[41] Two fishermen from Sonora in the Gulf of California were reported missing.^[42] Isolated heavy rainfall was reported in Sonora with a maximum rainfall total of 112 mm (4.4 in) falling in 24 hours, but there was no reported damage.^[43][44][24]

Arizona

The remnants of Lorena passed through Arizona on September 22–24, causing widespread severe thunderstorms and resulting flash floods.^[45] More than 8,000 customers lost electricity in the Phoenix area while flights at Phoenix Sky Harbor International Airport were delayed by hours, or cancelled.^[45] Precipitation peaked at 4 to 6 in (100 to 150 mm) near Phoenix.^[46] In preparation for the storm, free sandbags were offered to residents of Scottsdale to prevent flooding of households.^[47] Flash flood warnings were issued for much of the Phoenix metropolitan area.^[48] On September 23, a supercell thunderstorm produced a brief EF-0 tornado in New River in Maricopa County, the first time in 5 years the NWS Phoenix office had issued a tornado warning. Minor damage was reported in the area.^[46][49] Another EF-0 tornado very briefly touched down near Stanfield and was observed by a trained storm spotter, not causing any known damage.^[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.^[51][49][52] One resident driving in the affected area reported that over 40 trees had been uprooted.^[49]

A school bus with about 120 children on board was stranded in floodwaters, but they were safely rescued.^[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.^[53] Due to low visibility, a nearly submerged car needed to be "fished" out of floodwaters.^[53] A dust storm warning was briefly issued near Arizona State Route 85 as visibility became incredibly low.^[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.^[55][56]
