Another Phoenix heat record has been broken. Here's our tally of all the records broken during heat wave

The list of broken heat records in the Phoenix area keeps getting longer with another two records broken on Wednesday morning and three more on Tuesday.

Arizona's current heat wave is different from all the ones in the past because of how long it has lasted, said meteorologist Matthew Hirsch with the National Weather Service in Phoenix. The heat event seems unlikely to let up anytime soon with temperatures forecast to be above 110 degrees through the weekend.

Valley residents were advised to take the heat "very seriously," and to stay indoors and hydrated as much as possible, Hirsch said. Cooling and hydration stations are open across the Valley at nonprofits, churches, libraries and recreation centers. The map of locations can be found at
