The first day of a nearly weeklong heat advisory affecting much of Southern California begins Wednesday.
“Today is expected to be one of the warmest days, with the hottest day of the week potentially tomorrow,” KTLA’s Kirk Hawkins said.
Heat advisories and extreme heat warnings will be in effect from Wednesday morning through Monday evening.
Most of the region, except coastal areas, will be under a heat advisory for hot daytime conditions, with high temperatures commonly ranging from 97 to 107 degrees, according to the National Weather Service.

An extreme heat warning is in place for the Antelope Valley, where temperatures are expected to range from 100 to 108 degrees, and for the Inland Empire, where afternoon highs are forecast to reach the upper 90s to 110 degrees, according to the Weather Service.
Meteorologists are also concerned that warm overnight temperatures could pose an additional risk.
“The overnight lows will be well above normal through the period, and this will not allow people’s bodies to recover from the day’s heat in houses without AC,” forecasters said.
Residents are urged to adjust their plans to limit strenuous outdoor activities during the hottest part of the day and seek air-conditioned spaces. Elderly neighbors and loved ones should be checked on frequently, and motorists should always check the back seat for children and animals.
The high-pressure system is expected to shift east on Tuesday, allowing the advisories to expire while temperatures remain above normal.
