The National Weather Service warns much of the California coast faces the threat of some flooding today because of a combination of high surf and unusually high tides.
The highest high tides this week are expected today through Thursday during the mid-morning hours, with water levels expected to range from 7 to 7.5 feet during the highest tide each day, a National Weather service statement said.
A coastal flood advisory will be in effect from 7 a.m. today to 2 p.m. Friday in Los Angeles County. Coastal flood advisories also will be in force in Ventura, Santa Barbara, San Luis Obispo, San Diego and Orange counties. The advisory issued for Orange County will expire at 9 p.m. Thursday.
Also forecast is long-period northwest swell Wednesday through Friday, with a potential for high surf on west- to northwest-facing beaches, an NWS statement said.
“There will be a risk of coastal flooding during this time as elevated water levels result from the combination of building surf and unusually high tides,” it said. Locations prone to coastal flooding include Long Beach as well as some coastal areas in Ventura and San Luis Obispo counties, it said.
Forecasters said the expected conditions could generate flooding of such low-lying areas as beach parking lots, adjacent streets and, possibly, structures.
Warm temperatures are expected today. The NWS forecast highs of 73 in San Clemente; 76 in Laguna Beach; 77 in Newport Beach; 78 in Avalon; 79 at LAX; 81 on Mount Wilson; 83 in Long Beach, Anaheim, Palmdale and Lancaster; 84 in Fullerton and Mission Viejo; 85 in downtown L.A. and Yorba Linda; 86 in San Gabriel; 87 in Pasadena, Burbank and Saugus; and 88 in Woodland Hills. Wednesday’s highs were expected to be a little lower.
