The most recent heat wave to sweep across Monrovia is expected to keep temperature highs near the triple digits through Wednesday, according to the National Weather Service.
A high of 103 degrees is expected Tuesday in Monrovia with a high of 98 degrees forecast on Wednesday, the NWS reports. Temperatures should drop down into the lower 90s as the weekend approaches.
The most recent heat wave is caused by "strong upper level high pressure over the desert southwest combined with weak onshore flow near the surface," according to the NWS. High temperatures should persist through Wednesday in the valleys, lower mountain areas and deserts, NWS said.
"The only escape from the heat will be the beaches...where daytime high temperatures will generally be in the 70s," an NWS special weather statement states.
