As Southern Californians brace themselves for the holiday storm, the National Weather Service in San Diego highlights a series of weather advisories that could put a damper on festive celebrations. The forecast indicates that an atmospheric river is expected to bring heavy rainfall to the region, particularly on Christmas Eve. Coastal and desert areas are also gearing up for powerful gusts, with the San Bernardino Mountains and foothills facing the brunt of these conditions, according to the NWS San Diego's latest advisory.
Travelers and residents should be wary of the imminent weather conditions, as rain totals could significantly disrupt Christmas Day plans. Showers are projected to persist through the holiday, with "locally heavy and more scattered rain showers" on the agenda. Additionally, snowfall is likely in higher elevation areas beginning Thursday night, with snow levels expected to drop significantly, impacting mountainous regions and potentially leading to slick driving conditions, per the NWS San Diego forecast.
But the troubles don't end there, the region is on high alert for flash flooding risks, which are expected to peak through early Christmas morning. The NWS warns of potential highway flooding and advises on measures to secure outdoor furniture in anticipation of strong winds. The most potent gusts could reach 55 to 75 mph along desert slopes and foothills of the San Bernardino Mountains. With such volatile conditions, the risk of tree damage is a tangible concern for communities across the affected areas.
As for the marine forecast, boat owners and beachgoers are advised that gale force winds will churn up seas and reduce visibility, leading to the possibility of thunderstorms and hazardous waves. The NWS has issued a Gale Warning effective until this afternoon, while beach hazards like elevated surf and minor tidal overflow remain a threat throughout today, especially during high tide this morning. Mariners are cautioned to remain vigilant and prepare for conditions that may require swift action to ensure safety.
As residents and visitors make their holiday adjustments, the NWS continues to monitor the evolving situation. Potential showers are likely to taper off over the weekend, but could also make a reappearance leading up to New Year's Day. The unpredictability of weather patterns during this season only emphasizes the need for relentless scrutiny and preparedness, especially in regions where such atmospheric disturbances can lead to significant disruptions and danger, notes the National Weather Service San Diego.
