Winter Storms in Mercer County: How to Prepare and Get Alerts

When a big storm is coming, a little preparation goes a long way. Here is how Trenton and Mercer County residents can sign up for official alerts, get ready for winter weather, and know where to turn when the power goes out.

Sign up for local alerts

The fastest way to get official emergency information is to opt in before you need it. Mercer County runs an emergency notification system that sends calls, texts, and emails about severe weather, road closures, and other emergencies. You can register through the county’s Office of Emergency Management page; alerts arrive with the caller ID “Mercer County Alert.” For help registering, the county lists OEM@mercercounty.org.

Turn on the alerts already in your pocket

Your phone can warn you for free. Wireless Emergency Alerts, the same system that sends AMBER Alerts, delivers National Weather Service warnings to WEA-capable phones automatically. The state Office of Emergency Management also recommends a NOAA Weather Radio for round-the-clock warnings. For forecasts, the National Weather Service office in Mount Holly covers the Trenton area.

Build a simple kit

You do not need a bunker, just a few basics ready before the storm:

• Several days of water and non-perishable food, plus any medications.
• Flashlights and fresh batteries, and a phone charger or power bank.
• Warm layers and blankets in case the heat goes out.
• A plan for how your household will stay in touch if cell service is spotty.

The state’s preparedness site at nj.gov/njoem has full checklists. Residents with disabilities or access needs can pre-register with the state’s Register Ready program at registerready.nj.gov so responders can plan to help.

During and after the storm

Call 911 for any emergency. For downed lines or outages, contact your utility. Stay off the roads during heavy snow so plows and emergency crews can work; if you must travel, our guide to getting around Trenton covers the transit options. County and municipal officials post closures and updates through the alert system and social media.
