A round of stormy weather Friday sent mud oozing down from the hills on Sierra Madre streets. Moisture coming from the storm covered some mountain communities with blankets of snow. Thunderstorms roamed across the Mojave Desert and rain was falling in many areas, making for a rare, soggy start to a Memorial Day weekend in Southern California. Some of the rain was welcome due to the extremely dry conditions that have caused a number of wildfires. Dirty brown water and sludge washed onto the roads in a densely populated canyon near Sierra Madre below foothills that were burned bare by a recent wildfire. Some roads were closed briefly before a skip loader was brought in to clear the area as road crews standing in foot-deep mud wielded shovels.
