KTLA reports that a beloved scenic route for many Southern Californians, Topanga Canyon Boulevard, won't see any cars until at least Monday afternoon. The recent storms have left the hillsides in a precarious state, increasing the risk of debris flows, particularly with more rain on the horizon.

Caltrans crews, after reviewing the National Weather Service's outlook, expect up to 0.59 inches of rain on Monday morning. This forecast prompted the decision to extend the road closure—between Pacific Coast Highway and Grand View Drive—beyond the usual midnight to 5 a.m. shutdown for repair work. The downpour, hitting slopes already saturated from earlier storms, may trigger new slides.

According to Caltrans District 7, maintenance crews have already been contending with moderate debris flows and larger rockfalls that occurred overnight on Saturday. Their work to clear up the aftermath continues, while actively keeping an eye on the current conditions.

Despite the challenges at SR-27, officials have reported no significant issues along State Route 1/Pacific Coast Highway. Caltrans District 7 promises updates through news releases and on social media platforms like Instagram, X (formerly known as Twitter), and Facebook, while monitoring the situation.

The route's closure is part of a broader narrative, one involving recovery from the Palisades Fire and damage inflicted by winter storms. For those needing real-time updates on traffic conditions, Caltrans Quickmap remains a reliable resource.
