Powerful storms, intense flooding and extreme heat are predicted to be hallmarks of this winter — but a little preparation could save a lot of damage to your home.
Extreme weather is set to intensify, at least through early 2027, thanks to an El Niño system that’s developing over the Pacific. Depending on where you live, that could mean floods and intense storms or drought or extreme heat.
“For homeowners, the biggest takeaway isn’t necessarily that we’re going to have a crazy winter,” says meteorologist Crystal Egger. “It’s that the potential for bigger swings in weather and more impactful storms deserves some attention now, before those storms arrive.”
Ahead, experts and home pros share what this winter’s El Niño could mean for your house — and the fixes worth making now, before the first storm hits.
What Is El Niño?

El Niño is a weather pattern that occurs when the Pacific Ocean is warmer than normal. That extra heat shifts atmospheric circulation, creating atypical weather around the world.
“As a result, some areas of the U.S. are drier than usual, and others are wetter,” says risk expert Melanie Musson. “So, you can expect huge winter storms in some places, and drought in others.”
How Are El Niños and Super El Niños Different?
They both represent the same weather pattern. However, super El Niños, like the one developing this year, have a stronger influence on large-scale weather patterns.
Why This Winter’s El Niño Is a Bigger Deal Than Usual
This year, the Pacific became much warmer than usual and earlier than usual, prompting scientists to predict that it could become the strongest El Niño ever. While El Niño is a natural cycle, scientists agree that this year’s event is likely intensified by climate change.
How El Niño Could Affect Your Region
Southwest
In general, meteorologists are predicting a wetter winter for Southern California and parts of the Southwest, with greater potential for heavy rain, flooding, mudslides and debris flows.
Pacific Northwest
Here, El Niño could mean a warmer and drier winter overall, says Egger, although individual storms cold still bring significant rain, wind and mountain snow.
Rocky Mountains
While the southern and central Rockies may receive above average snowfall, El Niño often means lower snowpack in the Northern Rockies (though some meteorologists are predicting heavy snowpack in Montana).
The South
Winter could be wetter in the southern tier of the U.S., with increased potential for heavy rain, flooding and severe thunderstorms. “When cold air is in place, some storms can also bring ice, freezing rain or snow, creating travel problems, power outages and property damage,” says Egger.
Northeast and Midwest
El Niño’s influence is less consistent here, says Egger. “Some areas can experience warmer-than-average temperatures and changes in snowfall, but local outcomes depend heavily on the individual storm track and other atmospheric patterns.”
The Home Risks to Watch For

It depends on where you live. In drier areas, wildfires are an obvious risk. Otherwise, the most significant concern is severe storms, bringing flooding, mudslides, power outages, fallen trees and frozen pipes.
“One of the most overlooked risks is water,” says Egger. “A home doesn’t have to be in a flood zone to experience water damage. Heavy rainfall can overwhelm drainage systems, expose weak points around roofs and foundations, and create localized flooding.”
The condition of a house also plays a large part in how well it will fare. “Two homes can experience exactly the same storm and have completely different outcomes, because one has good drainage and maintenance while the other has years of deferred repairs,” says real estate professional Lisa Martinez.
How to Prepare Your Home Now
Start now, before the weather turns bad. “Five minutes of preparation on a sunny day can prevent hours of headaches during a storm,” says Egger.
Maintenance tasks to catch up on include:
- Clean gutters and add downspout extensions to direct water away from the house.
- Inspect the roof for damaged shingles and flashing. “If shingles appear shiny or have lost their granules, it may be time for a closer inspection or replacement,” says Andrea Bessling with Allstate.
- Check drainage around the property. Make sure you understand where water is likely to go, and redirect it away from your home through grading, French drains, etc.
- Trim potentially hazardous branches away from the roof.
- Seal exterior cracks around windows and doors, and inspect weather stripping.
- Fix poorly closing doors and windows.
- Keep materials and tools on-hand for boarding up windows and clearing post-storm debris.
- Know how to shut off your utilities.
- Test the sump pump and backup generator.
- Add smart water sensors near water heaters, sinks and basement corners.
- Re-examine your insurance policy to ensure your coverage matches your weather risks. Remember, flooding isn’t typically covered by standard policies.
- Buy a whole home or portable battery backup system to keep essentials running (like the Anker SOLIX E10 or S2000).
Also, have a plan of action in place, for when a storm does arrive, including:
- An evacuation plan and way for your family to stay in touch if cell service goes out (like this emergency communications kit from Midland).
- An emergency kit, with essentials including water, non-perishable food, a first-aid kit, valuable documents, and more.
- Documentation of what’s in your home, like a room-by-room cellphone video, to help with insurance claims.
Should You Be Worried, or Just Prepared?
Just be prepared.“Don’t go into the rabbit hole of dread,” says Musson. “If you’ve done what you can to protect yourself, you should enjoy your fall, winter and spring without ruining them with stress.”
Egger agrees. “A strong El Niño doesn’t mean every homeowner is going to experience a disaster,” she says. “The best approach is to understand your local risks and take simple steps before the weather becomes a problem. You can’t control the weather, but you can control how prepared your property is for it.”
