PHOENIX -- The heat is on in the Phoenix metropolitan area.
Temperatures were expected to hit 112 degrees Friday in Phoenix with Surprise and Peoria potentially climbing to 114.
National Weather Service meteorologists told Phoenix TV station KTVK that it doesn't usually get this hot until the end of June.
They said Friday will rank as the hottest day of this year so far.
An excessive heat warning was in effect until 8 p.m. in Maricopa County, along with a high pollution advisory.
Heat is one of the leading weather-related killers in the nation. Authorities say up to 50 people in Arizona dying each year from excessive exposure to heat.
