ALBUQUERQUE, N.M. >> The weeklong heat wave that baked most of the U.S. Southwest in temperatures well into triple digits is on its last legs, but forecasters are still urging people to be cautious as there will be little relief from the warm weather until monsoon thunderstorms begin to kick in, likely in July.

A slight easing of temperatures is expected through the weekend, with Phoenix and Las Vegas falling short of besting any new records. Still, an excessive heat warning continues through Saturday in Las Vegas, where it’s never been hotter this time of year.

It was a record-high 110 degrees in Las Vegas on Friday, 113 in and 100 in Albuquerque.

Even in Florida, forecasters with the National Weather Service on Saturday warned that heat indices would be well into the triple digits for Miami and other areas. That measurement reflects what the temperature feels like when relative humidity is combined with the air temperature.
