Southern California to experience its closest brush 

As a tropical storm, Kay hit the coast of the Baja Peninsula in Mexico on Thursday. Southern California is likely to get a lot of rain and flooding because of it. 

Forecasters say that after Hurricane Kay made landfall Thursday as a tropical storm on Mexico's Baja Peninsula,

heavy rain and flooding could soon hit western states that are sweltering in a heat wave.

The National Hurricane Center said that Hurricane Kay hit near the middle of the 760-mile-long peninsula off Mexico's Pacific Coast.

It had sustained winds of up to 70 mph, heavy rain, and a strong storm surge. 

On Thursday night, the storm was about 370 miles south-southeast of San Diego, and the centre said that tropical storm warnings were in effect for most of the peninsula's east and west coasts.  

Kay is not expected to hit the U.S. mainland directly, but it is expected to bring strong winds, heavy rain, and flash flooding to California and

Arizona starting on Friday. It is very rare for a tropical cyclone to hit Southern California. In 1997, Hurricane Nora hit southeastern California as a tropical storm.

It knocked out power in Los Angeles and caused flooding in San Diego. The Kay is expected to bring 2–4 inches of rain to southern California and 1–2 inches to southwest Arizona.
