A pacific storm system will likely bring widespread light to moderate rainfall across Southwest California Wednesday into Wednesday night. There is a slight chance of heavier showers developing late Wednesday afternoon into Wednesday night across the region, including the Woolsey and Hill burn areas. Storm total estimates are between 0.25 and 1.00 inches. If these rainfall amounts materialize, there will likely be rockslides and mudslides in and around the Woolsey and Hill burn areas, especially Highway 1 and canyon roadways. There is a 20 percent chance of rainfall rates meeting first year USGS debris flow thresholds for the Woolsey, Hill, South, and Stone burn areas from late Wednesday afternoon into Wednesday night. The first year USGS thresholds are 0.50 inches in 1 hour, 0.30 inches in 30 minutes, and 0.20 inches in 15 minutes. The rainfall combined with potential mudslide/rockslide activity could cause significant travel delays on the already very busy holiday travel day on Wednesday, especially considering possible road closures.
