Unseasonable Weather Patterns Bring Rain And Thunderstorms To Southern California

As the mid-September sun hangs low, a sudden shift in weather is upon Southern California, bringing unexpected showers and thunderstorms. This unusual change is raising concerns about potential flooding and significant temperature drops well below the seasonal average. Residents and travelers alike are advised to stay alert as the weather unfolds over the next few days.

In the greater Los Angeles area, forecasts indicate that light rain or drizzling will occur on Thursday and Friday. However, there's a looming possibility of isolated thunderstorms that could lead to heavier rainfall in certain regions. Meteorologists are particularly cautious about the mountainous areas, where conditions are more conducive to severe weather.

According to Bryan Lewis, a meteorologist with the National Weather Service in Oxnard, “The forecast suggests we are looking at mostly less than a tenth of an inch, maybe up to a quarter of an inch in the mountains. However, if a large thunderstorm develops in a specific area, the rainfall could be significantly higher.” This type of weather pattern is quite abnormal for this time of year, given that September typically enjoys drier and warmer conditions.

Much of inland Ventura and San Luis Obispo counties, along with western Kern County and parts of Santa Barbara County, are currently under a flood watch on Thursday. Those living near the burn scars from the Hurricane and Apache fires should be particularly vigilant, as the National Weather Service has indicated the risk for debris flows and flooding in these areas. Thunderstorms capable of producing heavy rainfall have been forecasted, with rates potentially reaching half an inch in just 30 minutes.

Additionally, the aftermath of the Apache fire, which scorched approximately 1,500 acres near Ojai, and the Hurricane fire, which affected around 10,000 acres, remains a concern. Residents are urged to prepare for possible severe weather conditions that could exacerbate existing vulnerabilities. As this weather pattern settles in, it’s crucial for residents to stay informed and take necessary precautions.

Meanwhile, in the Sierra Nevada region, winter weather advisories have been issued for the highest peaks in Yosemite, Kings Canyon, and Sequoia national parks. These elevations above 9,000 feet are expected to receive between 2 to 5 inches of snow, indicating a significant shift in weather that could affect both visitors and local wildlife.
