Unprecedented heat wave in the western U.S. is breaking March temperature records by significant margins.
Millions in the West are facing heat watches and warnings as a dangerous heat wave grips the region, increasing fire risks amid dry conditions. Parts of California, Oregon and Washington state will experience "extreme heat" at least through Tuesday, with temperatures reaching over 100 degrees, according to the National Weather Service (NWS). "For many areas there will be little nighttime relief from the extreme heat, with overnight lows remaining well above normal. Numerous nighttime temperature records are likely," the NWS said in an advisory on Sunday.
