Understanding NWS Flood Warnings and Alerts

The NWS uses a tiered system of alerts to communicate the severity of potential flooding:

• Flood Advisory: Indicates potential flooding in the specified area. Take precautions and monitor the situation.
• Flood Watch: Conditions are favorable for flooding. Be prepared to take action if flooding develops.
• Flood Warning: Flooding is occurring or is imminent. Take immediate action to protect yourself and your property. This is an Active Flood Warning.

Understanding the difference between a flood, a flash flood, and a rapid rise flood is vital:

• Flood: A general and usually slower-onset inundation of normally dry land areas.
• Flash Flood: A rapid and often unexpected flood, typically caused by intense rainfall over a short period.
• Rapid Rise Flood: A flood that rises quickly, but not necessarily as suddenly as a flash flood.

The NWS delivers flood alerts through various channels:

• NOAA Weather Radio: A dedicated weather radio provides continuous broadcasts, including emergency alerts.
• Mobile Apps: Numerous weather apps (like the NWS app) send push notifications for relevant alerts.
• Websites: The NWS website (weather.gov) offers detailed forecasts and warnings.

Preparing for an Active Flood Warning

Proactive preparation is key to minimizing risks during an Active Flood Warning. Pre-flood preparedness involves:

• Developing an Emergency Plan: This plan should include designated evacuation routes, pre-arranged meeting points, and contact information for family members.
• Gathering Essential Supplies: Stockpile non-perishable food, potable water, essential medications, and important documents (stored in waterproof containers).
• Protecting Your Property: Move valuable items to higher ground. Consider sandbagging vulnerable areas.

Here's a checklist for preparedness:

• Secure loose outdoor objects that could be swept away by floodwaters.
• Create a family communication plan, outlining how to contact each other during an emergency.
• Prepare a "go bag" containing essential items like medications, clothing, and personal documents.

Responding to an Active Flood Warning

An Active Flood Warning demands immediate action. Evacuate immediately if instructed to do so by authorities. Follow these guidelines:

• Evacuation Procedures: Obey all evacuation orders promptly. Do not attempt to drive through flooded areas.
• Safe Driving: Never drive through flooded roads. The depth of water may be deceiving, and even a small amount can sweep a vehicle away.
• If Caught in a Flood: Seek higher ground immediately. Climb to the roof of your vehicle if necessary, but only as a last resort.

Here’s what to do in different scenarios:

• If caught in a flood: Move to higher ground immediately. Avoid downed power lines and debris.
• If you cannot evacuate: Move to the highest floor of your building. Secure yourself to a stable structure if necessary.
• Rescuing people or pets: Only attempt a rescue if you are properly trained and equipped. Your safety is paramount.

Post-Flood Safety and Recovery

Post-flood safety is crucial. Floodwaters can carry contaminants, posing health risks. Be aware of:

• Contaminated Water: Avoid contact with floodwater. Use bottled water for drinking and cooking.
• Downed Power Lines: Stay away from downed power lines – they may be live and extremely dangerous.

After the floodwaters recede:

• Returning Home: Check for structural damage before entering your home. Be cautious of weakened structures and hazardous materials.
• Damage Assessment: Thoroughly inspect your property for damage. Document everything with photos and videos.
• Seeking Assistance: Contact FEMA (Federal Emergency Management Agency) and the Red Cross for assistance with recovery efforts.

Here are some post-flood actions to take:

• Use caution when entering a flood-damaged home. Structural integrity may have been compromised.
• Report flood damage to your insurance company and local authorities.
• Seek assistance from FEMA, Red Cross, or other relevant agencies for financial aid and rebuilding support.

Conclusion: Staying Safe During an Active Flood Warning

Understanding Active Flood Warnings issued by the NWS, preparing for potential flooding, responding effectively during a flood event, and taking appropriate post-flood safety measures are all critical for minimizing risks. Heeding NWS flood warnings and alerts can save lives and protect property.
