An impending storm could cause "life-threatening" flooding in Mexico and the south-western United States, the US National Hurricane Center has warned, APA reports citing BBC.
Hurricane Hilary is moving towards Mexico's Pacific coast with winds of up to 130mph (215km/h). It is expected to make landfall later on Saturday.
Forecasters say it will then lose speed and become a tropical storm, moving towards southern California.
It would be the first tropical storm to hit California in more than 80 years.
In its first-ever tropical storm warning for the state, the National Hurricane Center (NHC) said "catastrophic and life-threatening flooding" were likely in the Mexican state of Baja California and the south-west US over the coming two days.
