The storm made landfall in southwestern US on Sunday afternoon, and could dump over a year’s worth of rain on California, Nevada and Arizona, Insider reported.
As of Sunday morning, the hurricane was downgraded to a tropical storm. Hilary is the first tropical storm to hit California in 84 years.
Before the tropical storm making landfall, major airlines — including Southwest, American Airlines, Delta, and United — waived fees to change flights for passengers that were flying this weekend, Insider reported.
Southwest Airlines, Harry Reid International Airport, and San Diego International Airport did not immediately respond to a request for comment from Insider, sent outside regular business hours.
