context_page_description: Hurricane Lorena was a strong tropical cyclone that brought heavy rainfall, flooding, and mudslides to Southwestern Mexico and the Baja California Peninsula in September 2019. Lorena was the thirteenth named storm and seventh hurricane of 2019 Pacific hurricane season. Lorena formed from the stronger of two disturbances off the coast of Mexico. The disturbance closest to Mexico became Tropical Storm Lorena, while the other disturbance became Tropical Storm Mario. Lorena strengthened in a favorable environment, and made landfall as a 75 mph Category 1 hurricane in southwestern Mexico on September 18, but weakened back to a tropical storm due to land interaction. However, after moving back over water between Baja California Sur and mainland Mexico, Lorena re-strengthened into a hurricane, and reached its peak intensity with 85 mph winds and a minimum barometric pressure of 986 millibars. Lorena made a second landfall on Baja California Sur, and quickly weakened thereafter. Lorena degenerated to a remnant low over the Gulf of California. The remnant low moved inland over Mexico and quickly dissipated.
context_section_description: At 15:00 UTC September 11, the NHC noted the possibility of a low pressure region forming off of the Central American coast. At 6:00 UTC September 14, a low pressure area formed and slowly developed and by 15:00 UTC September 17, it developed into Tropical Storm Lorena off of the coast of Mexico. Lorena gradually moved northwest towards the coast of Mexico while strengthening and by 3:00 UTC September 19, Lorena reached an initial peak intensity of 75 mph. Interaction with land caused Lorena to weaken below hurricane status by 15:00 UTC September 19. Lorena continued moving west-northwestward and regained hurricane status by 15:00 UTC September 20. Lorena would intensify further and peak at 21:00 UTC September 20 with winds at 85 mph and a pressure of 985 millibars. By midday on September 21, Lorena's structure began to deteriorate. Due to increasing wind shear and weakening caused by the mountainous terrain of Baja California, Lorena degenerated into a tropical depression by mid-morning on September 22, becoming a remnant low by that evening.
