The Southland will bake in summer-like heat for one more day today, while some parts continued to see high surf, perilous rip currents and possible flooding.
A high surf advisory issued by the National Weather Service will be in effect until 9 a.m. Saturday along the Los Angeles County coast and until 4 p.m. Saturday along the Orange County coast, where a coastal flooding advisory also will be in effect during that 30-hour period.
The high surf -- the result of a large swell churned up by a strong storm system in the central Pacific Ocean -- will produce breakers of between 12 and 15 feet, NWS forecasters said.
"The highest waves will affect west- and northwest-facing beaches,'' according to an NWS advisory.
"Due to a combination of the large swell and wind waves generated by strong, gusty winds.
As the high surf begins pounding the coast, several days of unusually high heat will be coming to an end, although temperatures will remain mild.
The NWS forecasts highs of 77 today in Glendora.
Temperatures will fall another several degrees Saturday before beginning to climb back up somewhat on Sunday, according to forecasters.
Several heat records for a Jan. 4 were set in the region on Thursday -- 91 in San Gabriel, breaking the record of 87 set in 2001; 89 at UCLA, six degrees higher than the record 83 set in 2001; 88 in Long Beach, besting the record of 65 set in 1969; 85 at LAX, compared to 82 on Jan. 4 2001.
