Get ready for extra hot days throughout Southern California.

An excessive heat watch goes into effect for Los Angeles, Ventura, and Orange counties and the Inland Empire starting Monday morning. The National Weather Service warns the heat wave will stick around through Friday.

An excessive heat watch goes into effect until Tuesday night. We're talking upper 80's and mid 90's in the coastal areas and around 100 to 110 degrees in the valleys.

"As we get into Monday we're really going to pump up the heat here," said meterologist Adam Roser with the National Weather Service. "Monday is looking like the hottest day, Monday and Tuesday, and then we kind of knock it back down a little bit going toward the 100's by the end of the week."

Meanwhile, a red flag warning was issued Sunday for the mountain areas of L.A., Ventura and Santa Barbara counties and is set to expire Tuesday.

Monsoonal moisture on Wednesday will cool off the region slightly, but will boost humidity.
