Once again this Spring, rains have bogged down the Santa Clarita area with over 3 inches worth of falling water.
Strong winds and heavy rains produced dangerous conditions for motorists throughout much of Los Angeles County today. Trees have fallen and knocked down many power lines leaving dozens of communities without power.
The storm, which lasted a little bit over 9 hours, caused major traffic collisions along the freeways and incurred visible damage to Santa Clarita utilities.
While the storm kept most would-be drivers at bay, emergency service personnel were kept busy with numerous wrecks and single vehicle accidents throughout the day. In the hillside communities, multiple flash flood and landslide warnings were issued as the fire damaged areas rapidly collected rainfall.
Landslides occur when large swaths of earth and rock slip or sag due to a combination of earth movement or a significant loss of vegetation, erosion and heavy rains.
Flash floods, on the other hand, occur when dry riverbeds or low lying basins rapidly absorb water and become super-saturated. This super-saturation no longer lets the ground absorb water at a rate greater than the amount of rain that is falling, thus it backs up on the surface of the affected area.
With winds gusting between 10 and 15 mph, the rain continues to fall across the Santa Clarita Valley. Motorists are advised to drive cautiously and use headlights at all times.
Check your tires for any balding, or lack or tread before leaving your location.
The storm is expected to last throughout the night, and much of Monday.
Those who are planning to travel on any major freeway Monday morning are advised to leave 45 to 65 minutes early as heavy traffic is likely.
