Understanding NWS Flood Warnings and Advisories

The NWS uses a tiered system to communicate flood threats: Flood Watches, Flood Warnings, and Flood Advisories. Understanding the differences is critical to taking appropriate action. These alerts are disseminated through various channels, including NOAA Weather Radio, mobile apps like the NWS app, and the NWS website. Staying informed is key to effective flood preparedness.

• Flood Watch: A flood watch means that conditions are favorable for flooding. Be prepared to take action should a warning be issued. Monitor weather reports closely.
• Flood Warning: A flood warning means that flooding is occurring or is imminent. Take immediate action to protect yourself and your property. Evacuation may be necessary.
• Flood Advisory: A flood advisory indicates that minor flooding is occurring or is expected. Be aware of the potential for flooding and take precautions.

Signing up for weather alerts through your mobile device or local emergency notification system is crucial. Regularly check the NWS website (weather.gov) or their mobile app for updates and forecasts. A NOAA Weather Radio with Specific Area Message Encoding (SAME) is also an excellent tool for receiving timely warnings.

Evacuation Procedures During a Flood Warning

When a flood warning is issued, or an evacuation order is given, immediate action is paramount. Delaying can be life-threatening. Having a pre-planned evacuation strategy significantly increases your chances of safe escape.

• Develop a Family Evacuation Plan: This plan should include designated meeting points, contact information for family members, and pre-determined evacuation routes.
• Pack an Emergency Kit: Your kit should contain essential supplies such as water (one gallon per person per day for at least three days), non-perishable food, medications, first-aid supplies, flashlights, batteries, a portable radio, and important documents.
• Identify Your Evacuation Zone and Routes: Know your designated evacuation zone and the established evacuation routes. Familiarize yourself with these routes beforehand. This will save valuable time during an emergency.
• Know Where to Find Temporary Shelters: Locate nearby shelters or designated evacuation centers in advance. Knowing their location will be crucial during a rapid evacuation.
• Evacuating Pets: Remember to include your pets in your evacuation plan. Ensure you have carriers and supplies for them.

Safety Measures During a Flood: In-Home and Outdoor

Taking proactive measures before, during, and after a flood is crucial for minimizing damage and ensuring personal safety.

Before a Flood:

• Secure your home by moving valuable items to higher ground.
• Disconnect electrical appliances to prevent electrocution.
• Learn how to shut off utilities (gas, electricity, water).
• Consider using sandbags or waterproof barriers to protect your home's foundation.

During a Flood:

• If caught in a flood, move to higher ground immediately.
• Avoid walking or driving through floodwaters; the depth and current can be deceivingly dangerous. Floodwaters may contain contaminants and debris.
• Never touch downed power lines.
• Listen to the radio for updates and instructions from emergency services.

After a Flood:

• Assess the damage carefully; avoid entering flood damaged structures until deemed safe by authorities.
• Be aware of the dangers of contaminated floodwaters; use protective gear when cleaning up.
• Report damage to your insurance company and local authorities.
• Be cautious of structural damage and unstable ground.
