Sunday, September 7, 2025 — A severe thunderstorm watch was issued for parts of the northeastern United States on Sunday. The watch warns people that conditions could become dangerous in the coming hours. Local weather offices say storms could form and grow fast.
A severe thunderstorm watch means the atmosphere is ready to make strong storms. It does not mean the storm is happening right now. It means the chance of severe storms is higher than normal. The National Weather Service defines a severe thunderstorm as one that can make hail at least one inch across or winds of 58 miles per hour (or stronger). Watches are usually set for several hours so people can prepare.
Watches are often issued by the Storm Prediction Center or by local weather offices. These agencies watch the big weather patterns. They look at radar, satellites, and computer models. If they see a risk that a cluster of storms could become severe, they issue a watch for the area. People in the watch area should stay alert and follow updates.
What hazards come with these storms? The main threats are very strong winds and large hail. Heavy rain can also fall in a short time. That rain can cause flash flooding in low places or places with poor drainage. In some cases, a storm under a watch can also produce a tornado. When a severe thunderstorm is on the ground or seen on radar, the watch can be upgraded to a warning. A warning means you should take shelter immediately.
Local reports on Sunday said the watch covered parts of Maine and nearby areas. Weather forecasters said storms could develop in the afternoon and evening. People in the watch area were told to expect sudden gusts, possible hail, and heavy downpours. Power outages and downed tree limbs were possible if winds become strong. Residents were urged to secure loose outdoor items and prepare for quick changes in weather.
Here are simple safety steps to follow during a watch or storm:
- Keep a battery radio, phone, or app ready for alerts.
- Move cars under cover if hail is expected.
- Bring pets and outdoor items inside.
- If a warning is issued, go to a safe room or an interior room on the lowest floor. Avoid windows.
- Do not drive into flooded roads. Turn around, don’t drown.
Where to find the latest information:
- Check the National Weather Service website or local NWS office pages.
- Watch the Storm Prediction Center for updated watch maps.
- Local TV and radio will give area-specific advice.
Emergency managers and utilities also post updates if power or roads are affected.
A watch lets people plan and act before danger arrives. It is a helpful early step. But it should not be ignored. If conditions change and a warning is issued, take it seriously and seek shelter right away. Officials ask everyone in a watch area to stay tuned and be ready to move fast if needed.
