The National Weather Service announced they expect the heaviest rain to hit recent burn areas Tuesday to occur between 9 a.m. and 2 p.m.
The storm may bring one to two inches of rain in the valleys, with possibly two to four inches of rain in the mountains and foothills, the NWS said.
Over the weekend and through Monday, residents collected roughly more than 3,000 pre-filled sandbags given for free by the city. Since officials have been helping residents prepare for debris flows and mudslides in February of 2014, Glendora has given away about 85,000 sandbags, said City Manager Chris Jeffers.
Meanwhile, the Los Angeles County Department of Public Works announced that starting Tuesday, Glendora Ridge Road and Mt. Baldy Road will be closed to where they meet Glendora Mountain Road.
