El Niño Could Bring Flooding this Fall and Winter
Flooding can happen almost anywhere, and conditions this year could raise the risk of heavy rain in parts of the United States.
One reason is El Niño, a weather pattern that begins with unusually warm water in the tropical Pacific Ocean. El Niño can change weather patterns across the U.S., including where and how much rain falls.
El Niño is strengthening now. NOAA says there is a greater than 90% chance it will become very strong during fall and winter 2026-27. As fall turns to winter, El Niño is expected to increase the chances of wetter-than-normal weather across parts of the southern U.S.
There is another piece of the science. Warmer air can hold more water vapor. When storms tap into that extra moisture, they can produce heavier rain. More moisture does not mean flooding will happen, but it can increase the potential for extreme rainfall when the right storm conditions develop.
That makes flood preparation important, even in places that do not flood often.
Know the electrical dangers of flooding:
- Prepare before heavy rain is expected. Gather your emergency kit, and unplug and move electronics to higher spots in your home.
- Never enter flooded areas including basements where electrical equipment such as appliances, outlets and cords may be energized.
- Stay away from downed power lines and anything they touch.
- Do not touch electrical equipment while wet or standing in water.
- Do not use electrical appliances that have been wet until they are inspected.
- Have a qualified electrician inspect a flooded electrical system before restoring power.
Flood conditions can change quickly. Preparing before the rain begins can help keep you, your family and your community safe.
