El Niño Is Strengthening. Here’s How South LA County Homeowners Can Get Ready Before the Rain
A sunny September afternoon can make winter storms feel far away. But if you own a home in Long Beach, Compton, Carson, Inglewood, Gardena, Torrance or one of our coastal neighborhoods, now is the useful time to look at your roof, drainage and insurance—while you can still make a plan without rain coming through the ceiling.
El Niño is already strengthening. In its September 10, 2026 outlook, NOAA gave a greater than 90% chance of a very strong El Niño during fall and winter 2026–27. NOAA also stressed that the weather effects associated with El Niño are more likely, but never guaranteed. That’s a seasonal outlook, not a prediction that any particular South LA County street will flood. cpc.ncep.noaa.gov
As a real estate broker who has worked in these communities for 12 years, I think the best response is practical: learn how water moves around your property, fix the small problems you already know about, and keep good records.
Start with the path water takes
Walk around your property and picture a sustained downpour. Does water run toward the garage? Pool beside the foundation? Spill from a downspout onto a walkway or into a low spot in the yard? A home can have drainage trouble even if it has never made a headline or appeared to be “near the coast.”
Clear gutters, downspouts and drainage paths; check for roof leaks; and handle any known trouble spots before storms arrive. LA County’s rain guidance recommends these steps and suggests preparing sandbags where they may be needed. If a drainage problem keeps returning, have an appropriate professional assess it rather than assuming a quick patch will solve it. Weathering LA Rain
For duplexes and other rentals, add a check of shared walkways, exterior stairs, garages and tenant access points. Give tenants a clear way to report a leak or blocked drain promptly.
Coastal cities have another layer to watch
In places such as Long Beach, Redondo Beach and nearby waterfront communities, rain is only part of the picture. The California Coastal Commission notes that storms, large waves, high tides and erosion can combine to increase coastal flooding; higher sea levels can allow impacts to reach farther inland. That does not mean every coastal property faces the same risk. Location, elevation, drainage and the specific storm all matter. coastal.ca.gov
If you own or are considering a coastal home, look beyond the view. Ask about past water intrusion, inspect vulnerable lower-level spaces, and review local coastal and flood information for that particular address.
Review insurance before you need it
One question I would ask my own insurer now: “What kind of water damage does my current policy cover?” Most homeowners policies do not cover flood damage. Flood insurance is separate, and National Flood Insurance Program coverage typically takes 30 days to become effective, with certain exceptions. Coverage terms and eligibility deserve a direct conversation with your insurance professional. agents.floodsmart.gov
You can also check an address on FEMA’s Flood Map Service Center. The map is a starting point for a property-specific discussion, alongside its actual drainage history and your insurer’s guidance. LA County advises residents to learn their property’s risk factors and clear drainage paths in advance. COUNTY OF LOS ANGELES
Buying or selling this season? Make storm readiness part of the conversation
Buyers: During inspections, ask about prior leaks, drainage work and water intrusion. Pay attention to grading, downspouts, roof condition, crawl spaces and garages. If you have questions about a finding, bring in the right specialist and obtain an insurance quote early enough to understand your options.
Sellers: Address known leaks and drainage issues, keep receipts for completed work, and discuss property condition and disclosure questions with your agent. A tidy exterior helps presentation; documented maintenance helps buyers understand what was done.
Real estate professionals: Help clients ask specific questions about the property rather than treating “El Niño” as a blanket description of risk. Build enough time into the transaction for inspections and insurance review, especially when a property has a history of water issues or a coastal location.
A simple pre-rain checklist
- Clear gutters, downspouts and surface drains.
- Check the roof and areas with a history of leaks.
- Look for places where runoff flows toward the home or garage.
- Photograph current conditions and keep repair records together.
- Review flood risk and insurance coverage for the address.
- Follow local weather alerts and prepare supplies before a storm is approaching. Weathering LA Rain
