Recognizing the Signs of a Flash Flood Emergency

Learning to identify the early warning signs of a flash flood is paramount. While official flash flood warnings from your national weather service are crucial, observing changes in your local environment can also provide vital clues. Rapidly rising water levels are a significant indicator. Don't underestimate the power of seemingly small waterways; they can quickly become raging rivers during a flash flood.

• Pay close attention to weather forecasts and alerts: Your local news and national weather service are your primary sources for flash flood warnings and watches. A flood watch indicates conditions are favorable for flash flooding, while a flash flood warning means flooding is occurring or is imminent. Act immediately upon receiving a warning.
• Look for rapidly rising water levels in streams, rivers, and normally dry areas: Even a slight increase in water levels in areas that usually remain dry should raise concerns. Observe the speed of the water rise; rapid increases are a major red flag.
• Notice the sound of rushing water approaching: The roar of approaching floodwaters is a clear and immediate danger signal. If you hear this sound, seek higher ground immediately.
• Observe sudden increases in water flow, even in seemingly small waterways: Creeks and drainage ditches that are typically calm can become raging torrents during a flash flood. Don't underestimate their power.
• Be aware of overflowing storm drains and ditches: Overwhelmed drainage systems indicate a high volume of water and an increased risk of flash flooding in your area.

Preparing for a Flash Flood Emergency: Pre-Flood Actions

Proactive steps before a flash flood emergency significantly reduces its impact. This involves creating an emergency plan and preparing your home and family. Knowing what to do before a flood occurs is as important as knowing what to do during one.

• Develop a family evacuation plan, including designated meeting points: Know your evacuation routes and have multiple meeting points in mind, both nearby and further away, in case you become separated. Practice your plan regularly, especially with children.
• Prepare a flash flood emergency kit with essential supplies: This kit should include water (one gallon per person per day for several days), non-perishable food, a first-aid kit, medications, flashlights, batteries, a portable radio, and important documents in waterproof bags.
• Identify safe high-ground locations in your area for potential evacuation: Know where you will go if you need to evacuate quickly. This could be a friend's house on higher ground, a designated community shelter, or another safe location.
• Consider flood insurance to protect your property: Flood insurance is often not included in standard homeowner's insurance policies. Check your coverage and consider purchasing a separate policy if necessary.
• Elevate valuable items in your home: Move important documents, electronics, and other valuable items to upper floors or higher shelves to protect them from potential flood damage.

Creating a Family Communication Plan

Effective communication is critical during and after a flash flood emergency. Having a reliable way to contact family members is crucial, especially if you are separated during an evacuation.

• Designate an out-of-area contact person: Choose someone outside of the affected area who can serve as a central point of contact for all family members. This person can relay information and help coordinate reunification efforts.
• Ensure everyone in the family has access to multiple communication methods: Cell phones, landlines, and even a pre-arranged meeting place can all be important in case one communication method fails.

Responding to a Flash Flood Emergency: During & After

When a flash flood warning is issued or a flood is imminent, immediate action is vital. Your priority is to ensure your safety and the safety of your family. Remember that flood waters can be extremely dangerous.

• Immediately move to higher ground: Never attempt to drive or walk through flood waters. The depth and speed of the water can be deceptive, and even a few inches of rapidly flowing water can sweep you off your feet.
• If trapped, move to the highest possible point and call for help: If you become trapped, find the highest point you can reach and call emergency services immediately. Stay put until help arrives.
• Stay informed about the flood situation through official channels: Continue to monitor weather reports and official updates for information on the evolving flood situation and any changes to evacuation orders.
• Avoid floodwaters after the flood, as they may be contaminated: Floodwaters can be contaminated with sewage, chemicals, and debris, posing significant health risks. Avoid contact whenever possible.
• Report any damage to authorities: After the floodwaters recede, report any damage to your property or infrastructure to the appropriate authorities.
