Active Storm Warnings in the Carolinas

An "active" storm warning means a hazardous weather event is happening right now in your area or is imminent. Ignoring an active warning can have severe consequences. The National Weather Service (NWS) issues several types of active warnings for the Carolinas, each signifying a different immediate threat:

• Hurricane Warning: This signifies hurricane conditions—sustained winds of 74 mph or higher—are expected within 36 hours. You'll likely see language like, "…a Hurricane Warning is in effect… expect hurricane-force winds within 36 hours…"
  • Action: Evacuate if ordered, secure your property, and seek shelter in a sturdy building.
• Tornado Warning: A tornado has been sighted or indicated by weather radar. The wording might be: "…a Tornado Warning has been issued… a tornado has been sighted… take immediate shelter…"
  • Action: Immediately seek shelter in a basement or interior room on the lowest floor of a sturdy building. Avoid windows.
• Severe Thunderstorm Warning: Severe thunderstorms with damaging winds (58 mph or greater), large hail (1 inch or greater in diameter), or tornadoes are occurring. You may see phrases like: "…a Severe Thunderstorm Warning… damaging winds and hail expected…"
  • Action: Seek shelter indoors, away from windows. If outdoors, seek sturdy shelter immediately.
• Flash Flood Warning: A life-threatening flood is happening or is imminent. The warning will state something like: "…a Flash Flood Warning… life-threatening flooding is occurring or is expected to begin shortly…"
  • Action: Move to higher ground immediately. Never drive through flooded areas.

Understanding Severity Levels

It’s vital to understand the difference between a "Watch" and a "Warning." A Watch means conditions are favorable for severe weather to develop. Stay informed and be prepared. A Warning, however, means severe weather is happening or is imminent. Take immediate action. The difference is crucial for timely and appropriate responses. Active warnings demand immediate action; watches require preparedness.

Expired Storm Warnings in the Carolinas

An "expired" storm warning means the immediate threat has passed. However, this doesn't mean you can completely relax. Even after a warning expires, significant hazards may linger:

• Lingering Hazards: Flooding can persist for hours or even days after heavy rainfall. Downed power lines pose an electrocution risk. Debris from fallen trees and structures can cause injury.
• Finding Information on Expired Warnings: Check the NWS website, local news sources, and weather apps for updated information and reports on damage.
• Reporting Damage: If you experience damage during or after a storm, report it to your local authorities. This data helps assess the impact of the storm and directs aid to affected areas.

Differentiating Between Warnings and Advisories

While warnings demand immediate action, advisories signify less severe conditions. A Winter Weather Advisory, for instance, indicates accumulating snow or ice, while a Flood Advisory suggests potential for minor flooding. Advisories warrant caution and preparedness, but not the same level of urgency as a warning.

Resources for Carolinas Weather Alerts

Staying informed is paramount in the Carolinas. Utilize these reliable resources:

• National Weather Service (NWS): The NWS website (weather.gov) and app provide detailed forecasts and warnings.
• Local News Stations: Local news channels and websites offer up-to-the-minute weather reports and alerts specific to your area.
• Reputable Weather Apps: Apps like AccuWeather, The Weather Channel, and WeatherBug provide real-time alerts and forecasts.
• Wireless Emergency Alerts (WEA): Your mobile device will receive emergency alerts from the NWS via WEA.
• Local Government Websites and Emergency Management Agencies: Check your county or city's website for local emergency information and preparedness guidelines.

Conclusion

Understanding the difference between active and expired storm warnings in the Carolinas is vital for your safety and well-being. Active warnings demand immediate and decisive action; expired warnings still require caution due to the potential for lingering hazards. By utilizing the resources mentioned above and developing a personal severe weather preparedness plan, you can significantly reduce your risk and protect yourself and your family. Stay safe with timely Carolina weather alerts, and remember, understanding Carolina storm warnings saves lives.
