The Southland was experiencing another day of extreme heat Sunday, but significant relief is on the way later this week, forecasters said.
An extreme heat warning was due to expire at 8 p.m. Sunday in the Antelope Valley. A less severe heat advisory was in place until 8 p.m. Sunday for the Santa Clarita, San Gabriel and San Fernando valleys, along with the Santa Monica Mountains Recreational Area, Calabasas, Agoura Hills, the San Gabriel Mountains and the inland coast including downtown.
Sunday’s highs reached 90 degrees in downtown Los Angeles, 97 in Van Nuys, 101 in Santa Clarita, 106 in Lancaster and 89 in Anaheim.
Those highs are expected to decline a few degrees each day this week though Friday before another warming trend next weekend, according to current forecasts.
A more robust marine layer cloud coverage is also expected early this week, expanding into most coastal valleys by midweek, according to the National Weather Service. There remains a low chance of thunderstorms each afternoon through much of the week, with the highest chances in the mountains through Tuesday.
At the coast, high astronomical tides were expected to affect low-lying beaches south of Point Conception with the possibility of minor coastal flooding starting with the evening high tide Monday and continuing through Wednesday. Predicted tide heights of up to 7.5 feet are expected between 8 and 10 p.m. each evening.
Beaches most susceptible to potential minor coastal flooding issues include those around Point Dume and near Long Beach. A coastal flood advisory was also issued for Orange County beaches from 6 p.m. Monday to 11 p.m. Wednesday.
