As the holiday season reaches its zenith, residents and visitors along the coast of Southern California are advised to brace themselves for various weather-related challenges. The National Weather Service in San Diego highlights a mix of dense fog, cooling temperatures, and strong gusty winds leading up to Christmas. According to NWS San Diego, "Locally dense fog will continue for coastal areas through around sunrise with improving visibilities during the morning." Those venturing out to the coast should expect improvements in visibility as the day progresses.
Moreover, the swift approach of a low pressure system will induce a shift in weather patterns, cooling inland from today, Christmas Eve, through Christmas Day. Showers are anticipated to move southward across Southern California in the late afternoon and early evening, potentially affecting holiday celebrations. The weather service projects rainfall to be "less than one-tenth inch near the coast to one-quarter to one-third inch in the mountains, with locally greater amounts."
The NWS has warned beachgoers of marine and coastal conditions due to high surf and seas and strong rip currents. This weather pattern undoubtedly adds an element of risk, particularly for inexperienced swimmers advised to remain out of the water. The NWS San Diego also reports that "Highs today" are expected to be "a few degrees cooler than Monday" in coastal areas. At the same time, inland regions, particularly in the mountains and valleys, may experience a decline of 4 to 8 degrees. It's a subtle reminder that nature remains firmly in control despite our best efforts to maintain a semblance of festive warmth.
For those concerned about the wind conditions, brace for "Gusty southwest to west winds for the mountains and deserts," which are anticipated to intensify during the afternoon. The NWS cautions that the "strongest winds are expected for this evening with gusts to 45 to 55 mph." Additionally, the snow level is forecasted to drop significantly by evening, possibly leading to a white Christmas above 7,500 feet. For residents and travelers in these regions, it's a time to remain alert and prepared for rapidly changing conditions.
Looking ahead to Wednesday, slight cooling near the coast and a markedly more significant chill for the high desert is forecasted. Temperatures will dip as much as 10 degrees for the high desert, while coastal areas can expect highs ranging from 60 to 64 degrees, according to NWS San Diego.
