Tropical Storm Hilary has already pummeled the northern Baja California Peninsula of Mexico, where it dropped torrential rain and caused catastrophic flooding. The storm has already claimed at least one life in Mexico after a family of five was swept into the sea while crossing a stream in the Baja California Sur state, according to local officials.
Catastrophic flooding is also expected for parts of Southern California, which is experiencing its first-ever Tropical Storm Warning. In fact, some areas may receive up to 8 inches of rain through Tuesday evening.
