Traffic was backed up for hours Sunday on Highway 126 in Fillmore as the mudslides in Los Angeles County continued to impact travel. Interstate 5 was closed Thursday, October 15th at the Grapevine. Highways 66, 138 and 58 also closed due to massive mudslides. The Grapevine reopened to southbound traffic by 4:15pm, with northbound lanes reopening by 6:30pm. Hundreds of cars and trucks were trapped in the mud and debris for up to 20 hours in some areas, according to reports. Many drivers rerouted as far north as Santa Maria, coming back down the 101 freeway. The torrential downpour that lasted for 30 minutes produced 1.81 inches of rain in Tehachapi, and at least 6 feet of mud on the roadways. The heavy rain is being attributed to what is being called the 1,000 year storm. Meteorologists are warning this may be a precursor to El Nino, which is expected to hit this winter.
