when did hurricane hilary hit california

Hurricane Hilary made landfall in the Mexican state of Baja California on August 20, 2023, as a tropical storm. It then moved into Southern California on the evening of the same day, August 20, 2023, bringing heavy rainfall and gusty winds to the region. Though it was initially operationally considered a tropical storm when it hit California, post-analysis indicates Hilary had degenerated into a post-tropical low over northern Baja California by the time it entered California. This was an unusual event, as tropical storms rarely maintain their characteristics in Southern California due to cooler ocean temperatures and typical weather patterns.
