Hikers and those looking to get outdoor exercise should do so early in the morning before the heat sets in.

“We are talking about extreme heat in your forecast, triple digits, and the possibility of records into the next few days, even if you live in the valleys, Inland Empire, High Desert, and you’re not under this excessive heat warning,” CBSLA Meteorologist Danielle Gersh said.

A cooling trend won’t arrive until Friday.
