Tropical Storm Hilary, a rare occurrence in California, brings heavy rain, flash floods, and strong winds to the state.
Hilary made landfall in Mexico's Baja California peninsula before moving northward into Southern California.
Some areas in Southern California could receive up to 10 inches of rain, causing flash floods and widespread damage.
The storm also brings gusty winds, large waves, landslides, mudslides, and debris flows, prompting a state of emergency declaration.
Hilary is the first tropical storm to hit Southern California since 1939 and is linked to climate change-induced extreme weather events.
Scientists attribute the increase in unusual and severe weather phenomena to climate change, altering weather patterns across the region.
