As winter approaches, the National Oceanic and Atmospheric Administration (NOAA) has released its U.S. winter outlook for December 2024 through February 2025. Driven by La Niña conditions, this season’s forecast anticipates marked weather patterns, with wetter-than-average conditions expected in the northern regions and a drier, warmer outlook for the South.
What is La Niña, and How Will It Affect This Winter?
La Niña, a climate pattern marked by an upwelling of unusually cold ocean water to the surface, is known for its influence on weather across the globe. For the U.S., La Niña typically creates a dynamic winter environment, with contrasting conditions across different regions.
Expected Conditions: Wetter North, Drier South
NOAA’s Climate Prediction Center forecasts a wetter-than-average winter for the northern half of the U.S. Areas likely to see increased precipitation include:
- Pacific Northwest
- Great Lakes region
- Northern and western Alaska
In contrast, southern parts of the country are expected to experience warmer, drier-than-usual conditions, including:
- Southwest
- Southeast
- Gulf Coast
- Lower mid-Atlantic states
Adding to this concern, NOAA has noted that drought conditions are likely to persist and even worsen across the central and southern Plains. As of October, over a quarter of the U.S. is facing moderate or more severe drought conditions, and this forecasted winter outlook offers little chance for significant relief in these areas.
Preparing Your Home for Seasonal Weather Shifts
With winter on the horizon and these La Niña-influenced patterns predicted, homeowners should take proactive steps to safeguard their homes. Here are some essential home maintenance tasks that may help mitigate winter weather risks, tailored to your region’s expected conditions:
- Clean gutters to prevent water backup and ice dams in wetter regions.
- Inspect the roof for leaks or weak areas that could let in moisture.
- Install storm windows if heavy rains or snow are anticipated.
- Change HVAC filters to maintain efficiency and indoor air quality.
- Manage humidity appropriately for your climate: consider a dehumidifier in wetter regions and a humidifier for drier areas.
- Seal windows and doors to keep out water and pests.
- Check carbon monoxide and smoke detectors to ensure they’re operational for winter heating.
Don’t Forget Your Insurance Policy
With heightened winter weather risks on the horizon, now is a great time to review your insurance policy to make sure you’re covered for seasonal hazards. This winter may increase the likelihood of certain issues, especially in wetter areas prone to water backups or freezing temperatures that can lead to burst pipes. Reviewing your policy now could give you peace of mind should unexpected weather arise.
Preparing Now Means a Safer Winter
Taking time to prepare your home and review your insurance coverage in advance can help you avoid the impact of unexpected winter weather. By staying informed about NOAA’s seasonal outlook and taking proactive measures, you can better protect your home and family this winter, no matter where you are in the U.S.
