More Rain Possible Across LA County; New Storm Anticipated Thursday - MyNewsLA. com

The Southland continues to battle unsettled weather as more rain is expected to fall across Los Angeles County on Tuesday. An upper low-pressure system remains parked over the region, causing scattered showers and isolated storms throughout the day. According to the National Weather Service (NWS), this pattern increases the risk of waterspouts, which means boaters and those on the water should stay alert for dangerous conditions. These unpredictable showers can pop up nearly anywhere, dumping brief but heavy downpours and small hail, especially in the foothills and mountain areas. Snow levels are forecasted to sit between 5,000 and 6,000 feet, with a chance of a few inches of accumulation in higher elevations. Temperatures will remain cool, with highs only reaching the upper 50s to low 60s. Monday's rainfall added to an already soggy weekend, with some parts of the region receiving significant precipitation. In the 24 hours ending at 9 p.m. Monday, places like Porter Ranch, Northridge, and La Canada Flintridge saw around 1.5 inches of rain. Mountain areas received even more, about 2 inches. Meanwhile, downtown Los Angeles recorded roughly three-quarters of an inch, with over an inch falling in Bel Air and Beverly Hills. The persistent rain caused various disruptions, including a landslide in the Santa Clarita Valley and mudslides in Malibu. Flooding was also reported along major routes such as the Golden State (5) Freeway and Antelope Valley (14) Freeway, causing traffic issues and safety concerns. Forecasters expect a brief break from the wet weather on Wednesday, with clearer skies giving residents a chance to dry out. However, the calm won't last long, as another storm system is predicted to sweep through Thursday or Thursday night. Rainfall amounts for this upcoming system are uncertain but are generally expected to be less intense than the earlier storms. Still, the NWS warns that even moderate rainfall can trigger significant runoff and impacts due to already saturated ground. Most areas could see between a half-inch and an inch of rain, while mountain and foothill regions might receive 1 to 2 inches. Some projections, about 30%, suggest these amounts could potentially double, based on AI models that have done well with recent weather predictions. Temperature-wise, Tuesday will be chilly across the board, with highs near 60 degrees from the beaches through downtown LA and the San Fernando Valley. The San Gabriel Valley will see temps in the mid-50s to around 60, while the Santa Clarita Valley will stay in the mid-50s. The Antelope Valley will be coolest, with highs only reaching the mid-40s to low 50s. Looking ahead, most forecasts agree that a notable weather shift is on the horizon by the weekend, bringing drier, warmer conditions just in time for the Thanksgiving holiday week. This change should provide some relief after a particularly wet and disruptive period for the region.
