The heat wave scorching California may be the worst in its history and now an offshore hurricane threatens to fan already raging wildfires

As Californians endure what could be the worst heat wave in state history, a rare hurricane offshore is poised to extend extreme temperatures already threatening rotating power

outages and also deliver powerful winds that could fan raging wildfires. Extreme heat, damaging winds and an increased fire threat will escalate across Southern California

from Thursday through Saturday as Hurricane Kay – forecast to make the closest pass to Southern California of any such storm since 1997 – aims to approach the western coastline of

Baja California. Parts of Southern California will see dangerously hot conditions on Thursday and Friday, as Kay causes strong, hot and dry winds to blow toward the Pacific

coast from inland desert regions – similar to Santa Ana Winds, according to meteorologists. That hot air gets compressed as it moves through the mountains, causing temperatures to

rise. As a result, Los Angeles will push triple-digit heat Thursday and Friday, with temperatures between 100 and 112 – with overnight temperatures set to fall only to the

mid-70s to mid-80s. San Diego is under an excessive heat warning, with temperatures up to 97 degrees forecast. Meantime, Kay’s winds could gust over 60 mph as winds around

the storm begin to interact with the mountainous terrain of Southern California. That could spell further trouble for firefighters battling the fast-moving Fairview Fire, which

has burned more than 19,000 acres since it started Monday.
