Hurricane Kay is moving up the coast of Baja California, and we should start seeing the effects by Friday night.
The high heat that's been broiling San Diego will "end abruptly and unusually" late Friday, according to the National Weather Service. Hurricane Kay is churning up off the coast of Mexico and is expected to generate heavy rains, beginning Friday night. Forecasters say "significant rainfall" is a solid bet across southern California and Arizona. Kay is expected to stay at hurricane strength until it's around 250 miles from San Diego, which only four other storms have done since 1950 and none since 1992.
