Flash Flood Warning: What To Do?

Flash Flood Warning: What You Need to Know

Flash floods are dangerous weather events that can occur with little to no warning. Understanding what a flash flood warning means and how to react can save lives. In this comprehensive guide, we'll cover everything you need to know about flash flood warnings, including how they are issued, what to do during a warning, and how to stay safe.

What is a Flash Flood?

A flash flood is a rapid flooding of low-lying areas in a short amount of time – usually within six hours – caused by intense rainfall, dam or levee failure, or sudden release of water. Flash floods are particularly dangerous because of their suddenness and the powerful currents they create. The force of moving water can easily sweep away vehicles, destroy buildings, and pose a significant threat to human life. According to the National Weather Service, flash floods are a leading cause of weather-related deaths in the United States.

How Flash Flood Warnings are Issued

The National Weather Service (NWS) is responsible for issuing flash flood warnings. The process involves several steps:

1. Monitoring: The NWS continuously monitors weather conditions, including rainfall, river levels, and soil moisture.
2. Forecasting: Using weather models and radar data, meteorologists forecast areas at risk of flash flooding.
3. Issuance: If conditions suggest a high risk of flash flooding, the NWS issues a flash flood warning. This warning includes the affected areas, the expected duration of the flooding, and specific instructions for safety.
4. Dissemination: Warnings are disseminated through various channels, including:
   • NOAA Weather Radio: A nationwide network broadcasting weather and hazard information.
   • Local Media: TV and radio stations broadcast warnings to their audiences.
   • Online Alerts: The NWS website and mobile apps provide real-time alerts.
   • Emergency Alert System (EAS): Used for urgent warnings via TV and radio.
   • Wireless Emergency Alerts (WEA): Text message alerts sent to mobile phones in affected areas.

Understanding the Warning

A flash flood warning is typically issued for a specific area and time period. It will include the following information:

• Location: The counties or areas affected by the warning.
• Time: The duration of the warning, including the start and end times.
• Hazards: The specific dangers associated with the flash flood, such as rapidly rising water and strong currents.
• Instructions: Guidance on what actions to take, such as seeking higher ground and avoiding flooded areas.

What to Do During a Flash Flood Warning

When a flash flood warning is issued, immediate action is crucial. Here are the steps you should take:

• Seek Higher Ground: The most important thing to do is move to higher ground as quickly as possible. This could mean climbing to an upper floor of a building, moving to a nearby hill, or evacuating to a designated shelter.
• Do Not Drive Through Floodwaters: It's never safe to drive through floodwaters. The depth of the water can be deceptive, and even a few inches of moving water can sweep away a vehicle. According to FEMA, half of all flood-related deaths involve vehicles. Turn Around, Don’t Drown® is the National Weather Service’s safety campaign that highlights this danger.
• Monitor Weather Updates: Stay informed by monitoring weather updates from reliable sources like NOAA Weather Radio, local news, and the NWS website or app.
• Be Aware of Your Surroundings: Pay attention to rising water levels and any changes in the environment that could indicate increasing flood risk.
• Evacuate If Necessary: If local authorities issue an evacuation order, follow their instructions immediately. Evacuate to a safe location and do not return until officials say it is safe.
• Stay Away from Floodwaters: Avoid walking or playing near floodwaters. The currents are strong, and the water may contain debris or contaminants.
• Secure Your Home: If you have time, secure your home by moving valuable items to higher levels and disconnecting electrical appliances. However, your safety is the top priority.

Staying Safe After a Flash Flood

The danger doesn’t end when the floodwaters recede. Here’s what to do after a flash flood:

• Wait for the All-Clear: Do not return to flooded areas until authorities have declared it safe. There may be structural damage or other hazards.
• Inspect for Damage: Once it's safe to return, inspect your home for damage. Look for structural issues, electrical hazards, and gas leaks.
• Document Damage: Take photos and videos of the damage for insurance purposes.
• Contact Your Insurance Company: File a claim with your insurance company as soon as possible.
• Be Cautious of Debris: Floodwaters often carry debris, including sharp objects and hazardous materials. Wear protective clothing and footwear when cleaning up.
• Clean and Disinfect: Thoroughly clean and disinfect any areas affected by floodwaters to prevent the spread of disease.
• Seek Assistance: If you need help with cleanup or recovery, contact local disaster relief organizations.

Preparing for a Flash Flood

Being prepared can significantly reduce the risk of injury or property damage during a flash flood. Here are some steps you can take:

• Know Your Flood Risk: Determine if you live in a flood-prone area. FEMA provides flood maps and risk assessments.
• Sign Up for Alerts: Register for local emergency alerts and warnings to receive notifications about flash flood threats.
• Develop a Flood Plan: Create a family emergency plan that includes evacuation routes, meeting places, and communication strategies. Practice the plan regularly.
• Build a Disaster Kit: Assemble a kit with essential supplies, such as water, non-perishable food, a first-aid kit, a flashlight, and a portable radio.
• Purchase Flood Insurance: If you live in a flood-prone area, consider purchasing flood insurance. Standard homeowners insurance policies typically do not cover flood damage.
• Protect Your Property: Take steps to protect your property, such as elevating utilities, installing flood barriers, and sealing basement walls.

Key Differences Between a Flash Flood Watch and a Flash Flood Warning

It's crucial to understand the difference between a flash flood watch and a flash flood warning:

• Flash Flood Watch: This means that conditions are favorable for flash flooding to occur in the specified area. It’s a time to be aware and prepared. You should monitor weather updates, review your emergency plan, and be ready to take action if a warning is issued.
• Flash Flood Warning: This means that flash flooding is occurring or is imminent in the specified area. It’s a time to take immediate action to protect yourself and your family. Seek higher ground, avoid flooded areas, and follow safety instructions.
