Much of Southern California has been placed under a heat advisory on Tuesday as the first day of a four-day heat wave arrives.
A ridge of high pressure will result in an extended period of hot weather this week, peaking on Wednesday and Thursday,” the National Weather Service (NWS) stated in its Tuesday forecast.
Above-average temperatures arrived Monday and will continue to climb on Tuesday, with the San Fernando Valley reaching the mid-90s. The high is expected to top out closer to 100 degrees on Wednesday and Thursday.
Even the afternoon high for downtown Los Angeles on Thursday will be around 92 degrees later in the week.
A heat advisory is in place for parts of Los Angeles and Ventura counties through 9 p.m. Thursday.
“There is a high risk for heat illness for sensitive populations, including the very young, the very old, those without air conditioning, and those active outdoors. Do not leave people or pets in closed vehicles,” the NWS stated.
The dayslong period of hot weather is expected to subside for at least part of the upcoming Memorial Day weekend.
“Your Friday-Saturday will be hot days, and then your Sunday-Monday, the last two days, at least a little bit closer to the average,” KTLA meteorologist Henry DiCarlo said. “A little bit better for any plans you might have outside.”
