Part of the 2019 Pacific hurricane season

Hurricane Lorena was a strong Pacific hurricane in September 2019 that brought heavy rainfall, flooding, and mudslides to Southwestern Mexico and the Baja California Peninsula and also brought severe weather to the U.S. state of Arizona. Lorena was the thirteenth named storm and seventh and final hurricane of the 2019 Pacific hurricane season. A tropical wave, originally from the North Atlantic, entered the East Pacific basin on September 16. With increasing thunderstorm development, Lorena formed as a tropical storm on September 17 alongside Tropical Storm Mario. Lorena made its passage northwestward and quickly gained strength before it made landfall as a Category 1 hurricane in Jalisco on September 19. Due to interaction with the mountainous terrain, Lorena weakened back to a tropical storm. 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. Lorena weakened to a tropical storm over the Gulf of California, and became a remnant low on September 22, shortly after making landfall in Sonora as a tropical depression. The remnant low moved inland over Mexico, and eventually dissipated inland over Arizona on September 24.

In preparation for the hurricane, hurricane warnings and watches were issued for most of the southwestern coast of Mexico on September 19 whilst hundreds of people were evacuated. Torrential rainfall brought in the states of Colima and Jalisco damaged thousands of hectares worth of crops and damaged at least 201 homes on the coastline. Damage in the agricultural sector between both states was substantial, causing the price of banana crops to rise in the state of Colima. Floods from rivers swelling in Colima blocked roads while landslides occurred across both states. On the Baja California Peninsula, dangerous surf caused a man to die attempting to save his child after being pulled out to sea. In addition, schools were entirely shut down for 506,000 students. 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. Damage from Lorena totaled $50 million (2019 USD) or greater, counting agricultural losses in Mexico and further damage caused in the U.S.[2]
