Identifying Active Severe Weather Alerts in the Carolinas

Knowing how to spot an active alert is the first step in protecting yourself during severe weather. Active alerts indicate an immediate threat, requiring prompt action.

Official Sources for Real-time Alerts:

Reliable sources are key to receiving timely and accurate information. Always rely on these official channels:

• National Weather Service (NWS) website and app: The NWS is the primary source for weather information in the US, providing detailed forecasts and alerts. Their website (weather.gov) and app offer real-time updates and customized alerts.
• Local news channels' websites and apps: Many local news stations provide up-to-the-minute weather reports, including active alerts specific to your area in the Carolinas.
• NOAA Weather Radio: This dedicated radio service broadcasts continuous weather information, including warnings and alerts. It's an excellent backup system, especially during power outages.
• Wireless Emergency Alerts (WEA) on your mobile phone: WEA sends urgent alerts directly to your phone, even if you don't have a weather app open. Ensure your phone's alert settings are enabled.

Key Characteristics of an Active Alert:

An active alert will have these clear indicators:

• Urgent and immediate warning language: Words like "warning," "immediate threat," and "take action now" signify an active alert.
• Specific location details: The alert will clearly state the counties, cities, or specific areas under threat. This ensures you know if your location is affected.
• Clear indication of the type of severe weather threat: The alert will specify the type of danger, such as a tornado warning, flash flood warning, or severe thunderstorm warning.
• Specific instructions on what actions to take: The alert will provide clear instructions on how to stay safe, such as seeking shelter, evacuating, or taking other precautions.
• An indicated timeframe for the alert's duration: Active alerts usually include a timeframe, such as "until 7 PM," indicating when the threat is expected to subside.

Visual Indicators of Active Alerts:

Active alerts are visually prominent:

• Bright color-coding on weather maps: Weather maps will typically use bright red or orange to highlight areas under active warnings.
• High-priority notifications on weather apps: Weather apps will push urgent notifications to your phone, often with loud sounds and prominent visual cues.
• Loud and insistent alerts from NOAA Weather Radio: NOAA Weather Radio will sound a distinctive, attention-grabbing alert tone to signal an active warning.

Recognizing Expired Severe Weather Alerts in the Carolinas

While an active alert demands immediate action, understanding when an alert expires is equally vital.

Signs an Alert Has Expired:

Several indicators show that an alert is no longer active:

• Lack of updates or new warnings from official sources: If official sources stop issuing updates or new warnings for the specific area, the alert has likely expired.
• News reports indicating the storm has passed or weakened significantly: News reports often provide updates on the progress and intensity of storms, indicating when the immediate threat has passed.
• No further alerts being issued for the affected area: The absence of new alerts signifies that the immediate danger has subsided.

Common Mistakes People Make with Expired Alerts:

Even after an alert expires, vigilance is essential. Common mistakes include:

• Ignoring changing conditions and assuming safety after an alert expires: Conditions can change rapidly, even after an alert expires. Remain aware of your surroundings.
• Failing to check for new alerts after an initial alert expires: Conditions can worsen or new threats can develop. Continue monitoring official sources.

Staying Safe After an Expired Alert:

Following an expired alert:

• Continue monitoring weather conditions for any potential lingering threats. The danger might not be entirely over.
• Assess any damage to property or surroundings. Take photos for insurance claims if necessary.
• Assist neighbours if needed. Check on elderly or vulnerable individuals in your community.
• Report damage to local authorities. This helps emergency services assess the overall impact and allocate resources effectively.

Different Types of Severe Weather Alerts and Their Implications in the Carolinas

The Carolinas face various severe weather threats, each requiring specific responses.

Tornado Warnings:

Tornado warnings indicate a tornado has been sighted or is likely imminent. Take immediate action: Seek shelter in a sturdy building's interior, away from windows.

Severe Thunderstorm Warnings:

Severe thunderstorm warnings signal the potential for damaging winds (58 mph or greater), large hail (1 inch or greater in diameter), and frequent lightning. Move indoors and avoid contact with water or metal objects during a severe thunderstorm.

Flash Flood Warnings:

Flash flood warnings indicate a life-threatening flood is happening or is imminent. Never attempt to drive or walk through floodwaters – they are often much deeper and faster moving than they appear. Evacuate if instructed to do so.

Hurricane Warnings:

Hurricane warnings mean hurricane conditions are expected within the specified area within 24 to 36 hours. Evacuate immediately if ordered to do so by local authorities. Be familiar with your designated evacuation routes and shelters in the Carolinas. Coastal areas are particularly vulnerable and require careful planning and adherence to evacuation orders.
