How to Prepare for the ‘Super’ El Niño Threatening California

California is preparing for the possibility of intense rainfall, flooding, and landslides. The phenomenon is expected for the end of 2026 in the southern part of the state. For this reason, experts recommend several preventive measures before the storms.

How likely is a «super» El Niño this year?

According to Los Angeles Times, there is a 75% probability of this climate phenomenon being exceptional. It is related to the warming of the central and eastern tropical Pacific.

NOAA (National Oceanic and Atmospheric Administration) estimates a 98% probability that it will be «very strong.» That projection corresponds to the quarter ending in December.

According to meteorologists cited by that outlet, a persistent tropical humidity current would discharge abundant rainfall. This would especially affect southern California over the coming months.

What is Los Angeles doing to prepare?

The office of Mayor Karen Bass activated its preventive planning in response to the phenomenon. Municipal employees meet regularly with the National Weather Service.

The objective is to reinforce areas affected by previous fires and reduce future damage. This includes debris flows, flooding, and strong winds.

Additionally, the county removes sediment from the San Gabriel, Eaton Wash, and Devil’s Gate reservoirs. This way it seeks to increase water capture and reduce overflow.

County Supervisor Lindsey Horvath recommended: «Know the risks of where you live.» According to her, those living near hillsides or burned areas should enroll in emergency alerts.

How should I prepare my roof before the storms?

Homes with previous leaks or roofs older than 12 years require prior inspection. According to Terry Heller, owner of a roofing company, waiting until the storm reduces available options.

According to his explanation, during heavy rain crews receive many requests at once. Therefore, they only manage to place temporary tarps instead of complete repairs.

Heller recommended hiring a roofer with a current state license. Additionally, he suggested verifying that license on the official website of the California State Contractors Board.

How should I check the drains of my house?

Esther Margulies, landscape architect at the University of Southern California, recommended checking home drainage systems. She suggested removing blockages and confirming that water drains correctly into the gutter.

Each drain can be tested with a hose to verify its operation. If water accumulates or the ground remains damp, a sump pump may be needed.

Additionally, Margulies proposed installing rain collection barrels. These containers, between 300 and 380 liters, allow water to be reused for later irrigation.

He also recommended aerating compacted lawns or reducing unnecessary pavement in the garden. This helps the surface absorb more water during rainfall.

When should I use sandbags?

Sandbags should only be used when water advances directly toward a door. They should be stacked in rows in front of the entrance, without tying them together.

The county offers a free sandbag distribution map. However, it is recommended to call first and verify the corresponding address.

What should I do with the trees on my property?

Trees require evaluation, especially if they are near homes or electrical lines. Alison Lancaster, arborist in Santa Monica, recommended hiring a certified specialist.

According to her explanation, that professional can detect cracks, weak joints, or internal tree deterioration. Additionally, she warned that removing
