Understanding the NWS Flood Warning System

The NWS utilizes a tiered system to alert the public about potential flood hazards. Understanding these alerts is the first step in effective flood preparedness.

Recognizing Flood Warning Signals

The NWS issues several types of alerts, each with different implications:

• Flood Watch: Conditions are favorable for flooding. Stay informed and be prepared to take action.
• Flood Warning: Flooding is occurring or is imminent. Take immediate action.
• Flood Advisory: Minor flooding is occurring or is imminent. Be cautious and aware of potential hazards.

You can receive these alerts through various channels:

• NOAA Weather Radio: A dedicated weather radio is the most reliable source for timely warnings, even during power outages.
• Smartphone Apps: Download weather apps from reputable sources like the NWS or your local news station. Enable location services for personalized alerts.
• Local News: Stay tuned to local television and radio broadcasts for updates and instructions from local authorities.

Understanding the alert level is crucial. A warning necessitates immediate action, while an advisory indicates a lower risk but still requires caution.

Interpreting Flood Forecasts

The NWS provides valuable tools for understanding flood risks, including flood risk maps and predictions.

• Flood Stage: The water level at which flooding begins in a specific location.
• Crest: The highest point a flood will reach.
• Expected Duration: The anticipated length of the flood event.

Utilize the NWS website (weather.gov) and mobile apps for detailed forecasts, including river forecasts and flood risk maps specific to your area. Knowing the projected flood stage and crest allows you to prepare accordingly and determine the best course of action.

Evacuating Safely During a Flood Warning

When a flood warning is issued, evacuation may be necessary. Preparation and a well-defined plan are critical.

Preparing for Evacuation

Assemble an emergency kit specifically tailored to flooding:

• Important Documents: Identification, insurance information, copies of essential documents (stored in a waterproof container).
• Medications: Prescription and over-the-counter medications with a supply sufficient for several days.
• Emergency Contact Information: A list of emergency contacts and family members with their phone numbers.
• Valuables: Small, irreplaceable items that can be quickly gathered.
• Food and Water: Non-perishable food items and plenty of bottled water (at least one gallon per person per day).

Plan your evacuation routes in advance, identifying multiple options in case one is blocked.

Evacuation Procedures

Follow these steps during evacuation:

• Turn off utilities: Gas, electricity, and water to prevent further damage.
• Move valuables to higher ground: Elevate furniture and other items to protect them from floodwaters.
• Lock doors and windows: Secure your home to deter looting or vandalism.
• Contact neighbors: Inform your neighbors about the evacuation and offer assistance if needed.
• Follow instructions: Obey instructions from emergency personnel and local authorities regarding evacuation zones and routes. Know your evacuation zone.

Staying Safe if Evacuation Isn't Possible

If evacuation is not possible due to circumstances, take these crucial steps:

Seeking Higher Ground

If you can’t evacuate, move to the highest level of your home:

• Upper floors: Seek refuge on the top floor of your house.
• Attics: If accessible, an attic can provide additional safety.
• Sturdy furniture: If water rises, climb onto a sturdy piece of furniture that will float.

Avoid basements and low-lying areas at all costs, as these are the first to flood.

Flood Safety Precautions

Take the following precautions when sheltering in place:

• Stay away from windows: Broken glass and flying debris pose significant dangers.
• Avoid electrical outlets and appliances: Water and electricity are a lethal combination.
• Monitor water levels: Keep a close eye on rising waters and be ready to act if conditions worsen.
• Contact emergency services: Call emergency services if you need assistance.

Post-Flood Safety Procedures

Returning home after a flood requires caution and careful assessment.

Returning Home Safely

When floodwaters recede, proceed cautiously:

• Inspect your home: Look for structural damage, electrical hazards, and gas leaks. Do not enter if damage is significant.
• Avoid contact with floodwaters: Floodwater is contaminated and can carry diseases. Wear protective gear.
• Use PPE: Personal Protective Equipment such as rubber boots, gloves, and eye protection is crucial when entering a flood-damaged area.

Reporting Damage and Seeking Assistance

Report damage to the appropriate authorities:

• Insurance company: Contact your insurance provider to file a claim for flood-related damages.
• FEMA: The Federal Emergency Management Agency (FEMA) provides assistance to flood victims.
• Local government agencies: Contact your local government for information on cleanup efforts and assistance programs.
