Understanding Storm Alert Systems in the Carolinas

The National Weather Service (NWS) is the primary source of weather information and alerts for the Carolinas. They utilize a standardized alert system to communicate the severity and immediacy of potential weather hazards. This system is critical for understanding severe weather in the Carolinas and preparing for its impact. Different types of alerts are issued depending on the specific threat:

• Tornado Warnings: Issued when a tornado has been sighted or indicated by weather radar. This is the most urgent alert.
• Severe Thunderstorm Warnings: Issued when severe thunderstorms producing large hail (one inch or larger in diameter) and/or damaging winds (58 mph or greater) are occurring.
• Flash Flood Warnings: Issued when a flash flood is already occurring or is imminent. This is a life-threatening situation.
• Hurricane Warnings: Issued when hurricane conditions (sustained winds of 74 mph or greater) are expected within 24 hours.

Understanding Alert Levels:

• Watch: Conditions are favorable for severe weather to develop. Stay informed and be prepared to act.
• Warning: Severe weather is happening or imminent. Take immediate action to protect yourself and your property.
• Advisory: Less serious weather conditions are occurring or expected. Exercise caution.

Reliable Sources for Carolinas Weather Information:

• National Weather Service (NWS): weather.gov
• NOAA Weather Radio: A dedicated radio channel providing continuous weather information and alerts.
• Weather.com: Offers detailed forecasts, radar, and alerts.
• AccuWeather: Another popular source for weather forecasts and alerts.

Identifying Active Storm Alerts

Active storm alerts require immediate attention. They are disseminated through various channels:

• Weather Radio: The NWS broadcasts alerts directly through NOAA weather radio, often with a piercing alert tone.
• Weather Apps: Most weather apps (like WeatherBug, The Weather Channel app) push notifications directly to your smartphone.
• Websites: NWS and other weather websites update their information constantly, displaying active alerts prominently.
• News Media: Local news channels and websites also broadcast active alerts.

Visual Cues of an Active Alert:

Active alerts typically use bold lettering, urgent wording (e.g., "IMMEDIATE ACTION REQUIRED," "LIFE-THREATENING"), and clear geographic information (specifying the affected county or region). See examples below:

Confirming Alerts:

Always confirm alerts from multiple sources to ensure accuracy. Don't rely on just one app or website.

Immediate Action:

Upon receiving an active alert, take immediate action based on the specific threat. This might include seeking shelter, evacuating, or taking other protective measures.

Recognizing Expired Storm Alerts

Expired alerts are usually communicated with a clear timestamp indicating when the threat has passed. Cancellation messages will also often be included. However, be aware that even after an alert expires, lingering hazards might remain:

• Floodwaters: Floodwaters can remain dangerous for hours or even days after a storm.
• Downed Power Lines: Never approach downed power lines; they can still be energized and dangerous.
• Debris: Flying debris can cause damage long after the storm has passed.

Even after an alert expires, it's crucial to exercise caution and check for hazards. Resources such as local emergency management websites and the Red Cross provide valuable information on post-storm safety and damage assessment.
