Rain fell across parts of the Southland Tuesday, accompanied by thunder and lightning in some areas, as lingering moisture from Hurricane Marie brought another round of unsettled weather ahead of a heat wave.
Rain was reported in areas including Arcadia, Glendora, LAX and Manhattan Beach Tuesday morning, while thunderstorms produced lightning across portions of Los Angeles County.
The National Weather Service issued a special weather statement shortly before 9:30 a.m. Tuesday for a strong thunderstorm moving north through central Los Angeles County. Doppler radar tracked the storm near Whittier at 9:20 a.m., moving north at about 15 mph.
Forecasters warned of frequent lightning, pea-size hail and torrential rainfall that could cause localized flooding.
The wet weather comes as the region braces for another round of intense heat. A heat advisory will be in effect until at least 8 p.m. Thursday, with temperatures soaring into the upper 90s and triple digits.
“By Tuesday expect lots of areas of moderate to major heat risk for the coasts and coastal valleys, in particularly the LA Basin,” the NWS said. “Temperatures are expected to peak on Wednesday, with widespread major heat risk and highs largely 90 to 105 degrees.”
Overnight lows will offer little relief, remaining in the 70s and even the upper 70s Tuesday and Wednesday night.
A high surf advisory and coastal flood advisory were in effect until 11 p.m. Tuesday for portions of the Los Angeles and Orange county coasts.
Hurricane Marie remained well offshore but sent considerable moisture toward the area Sunday, with flooding reported in parking lots in Seal Beach and Zuma Beach, and “flowing into homes and streets” in Long Beach, according to the NWS.
Large breaking waves of 6 to 10 feet occurred at south- and southwest-facing beaches, with waves of 4 to 7 feet at west-facing beaches, along with strong and dangerous rip and longshore currents.
Several rainfall records were broken Sunday in Los Angeles County, including .70 inches in downtown Los Angeles, breaking the previous Sept. 6 record of .17 inches set in 1965.
Other records included .59 inches at LAX, 1.3 inches at Hollywood Burbank Airport, .68 inches at Long Beach Airport and .32 inches in Lancaster.
The Los Angeles County Department of Public Health issued an ocean water quality rain advisory for all county beaches until at least 2 p.m. Wednesday. Beach users were cautioned to avoid water contact for at least 72 hours after rainfall.
Officials had already urged inexperienced swimmers to stay out of the water because of dangerous rip currents.
