Heavy Rain & Flooding Reports

Heavy rain moved through Southern California on Monday, breaking into:

• Snow in mountain communities

Flood warnings and advisories were issued due to persistent water accumulation and poor drainage.

Stranded Drivers & Rescues

Floodwaters in Commerce and El Monte left drivers stranded. Emergency crews rescued several motorists after water levels rose quickly on major streets.

Flood Advisories & Ocean Water Warnings

• Flash Flood Warning lifted in parts of Los Angeles County
• Flood Advisory extended through 9 p.m.

SoCal Storm FAQ

Q1: Are more storms expected after this week?

Yes. Two additional storm systems are forecast to move through Southern California this week, bringing more rain and fluctuating weather conditions.

Q2: Why are ocean advisories in effect after rain?

Storm runoff carries debris, pollutants, and elevated bacteria levels into the ocean. Health officials recommend staying out of the water until advisories are lifted, typically 72 hours after rain stops.

Q3: Are only mountain areas affected?

No. While mountain regions saw snow and debris flows, coastal and valley areas experienced significant rainfall, flooding, and stranded vehicles.

Q4: Should I drive through standing water?

No. Driving through water-covered roads can cause vehicles to stall or wash away. It’s safer to avoid such areas and follow detour instructions.

Q5: What is a Flood Advisory?

A Flood Advisory means flooding has occurred or is imminent. Drivers and pedestrians should be cautious, especially near creeks, underpasses, and low-lying roadways.

Staying Prepared

Storm conditions can change rapidly. Residents and travelers are encouraged to:

• Monitor local weather reports
• Avoid non-essential travel during heavy rain
• Follow evacuation warnings in burn scar and flood-prone areas
• Stay updated with official advisories from local authorities
