The Los Angeles County Office of Emergency Management said Sunday evening that people should leave an area near Topanga Canyon because of the risk of mud or debris flows from storms going through.
Government officials say the warning is for zone 4 along Santa Maria Road, north of Topanga Canyon Boulevard. It starts at 9 p.m. and lasts until 6 a.m. Tuesday.
Authorities are telling people in the area to get ready for possible evacuations by getting their pets and loved ones together and keeping an eye on local weather news in case they have to leave.
Thunderstorms are most likely to happen on Monday from noon until late at night.
The rainy weather will make driving in the Southland dangerous because vision will be low and roads may flood.
KTLA weatherman Kai Goldberg said, “If you are going out, please be very careful driving over the next couple of days, especially on Monday morning when you are going to work or school.” “Monday morning is going to be very dangerous. The roads will be smooth. You should give yourself a lot of extra time to get to school or work.
