How to Check Flooding in Your Area

How to Check Flooding in Your Area

Flooding can cause major damage and disruption to homes, businesses, and infrastructure. Knowing if and when flooding may occur in your area is crucial to being prepared and staying safe. There are several ways residents can check for potential flooding in their area.

Monitor Flood Warnings from Local Authorities

The first step is to monitor warnings and announcements from local authorities. City, county, and state government agencies often have dedicated departments that monitor flood risks and issue emergency warnings.

Subscribe to email and text alerts from your local emergency management office or National Weather Service office. This way you’ll be notified immediately when flood watches and warnings are issued. Check government websites and social media regularly as well for updates.

Many areas also have emergency broadcast systems that send flood alerts over radio and TV. Tune into local stations during severe weather to stay up to date on the latest warnings.

Use Online Flood Mapping Tools

There are several free online flood mapping tools residents can use to assess their flood risk.

The NOAA National Weather Service has an interactive map showing the risk and potential severity of flooding across the U.S. Users can enter their address to view any flood hazards for their exact location. Real-time river gauges are also plotted on the map to see current water levels.

FEMA offers a similar flood map service that outlines high-risk 100- and 500-year flood zones. These are areas with at least a 1% and 0.2% chance per year of flooding, respectively. FEMA maps help identify required flood insurance zones.

For even more detailed street-level data, county government websites often provide localized floodplain maps. These show flood zones, floodways, and past flooded areas. Check with your county office of emergency management for access.

Check for Signs of Actual Flooding

While flood forecasts are helpful, it’s also important to directly check for signs of actual flooding when heavy rain is occurring or expected.

Monitor websites with live roadway cameras to visually check for flooded streets, underpasses, and low-lying areas. Also pay attention to official social media accounts, which often post real-time photos and reports of flooding from first responders and the public.

Step outside and look for water pooling in yards, fields, and parks near your home. Listen for gurgling sounds from storm drains and manholes, which can indicate backed-up sewers.

In more rural areas, keep an eye on streams and creeks. Rising water levels and debris accumulation are signs of potential overflow.

Have a Family Flood Plan Ready

In addition to checking flood forecasts and warnings, families should be prepared with their flood plan:

  • Know evacuation routes and shelter locations if told to evacuate
  • Have emergency kits packed with supplies ready to go
  • Keep important documents and valuables in waterproof containers
  • Review insurance policies and coverage
  • Plan for pet preparedness and care
  • Charge devices and have backup power options
  • Secure outdoor furniture and other loose, flood-prone items

Being proactive about flood awareness and preparation can greatly reduce risks and keep your family safe if flooding affects your area. Monitoring forecasts, using online tools, and watching for flood signs are all smart steps. But being ready to take prompt emergency action is key. Maintaining a flood plan ensures your loved ones know exactly how to respond and where to go if rising waters threaten your home.

Frequently Asked Questions About Checking for Flooding

What is the most accurate way to check if flooding will occur?

The most accurate way is to closely monitor forecasts and warnings from local emergency management agencies. They have professionals tracking real-time rain gauges, river levels, and weather patterns to issue alerts if dangerous flooding is imminent.

How far in advance can flooding be predicted?

General flood risk forecasts and flood plain maps can give a few days of advanced warning. More imminent flash flood warnings are typically issued just hours in advance due to the rapid nature of rising water.

What should I do if I receive a flood warning?

Take immediate precautions to protect your home and evacuate if directed. Head to higher ground, bring indoor belongings up to higher levels and turn off utilities if advised. Follow all instructions from emergency responders.

How can I find out if my home is at high risk for flooding?

Use FEMA’s flood map tool to enter your address and view if you are in a designated flood zone. High-risk areas have at least a 1% annual chance of flooding. Checking with your county can provide even more detailed local floodplain maps.

What steps can I take to prepare my home before a flood?

Buy flood insurance, stock up on emergency supplies, install check valves to prevent sewer backups, seal basement walls and windows, elevate utilities and wiring, clear debris from gutters and storm drains, and anchor fuel tanks and outdoor items that may float away.


Flooding can happen almost anywhere during heavy storms, so it is critical to stay vigilant about the potential risks. Monitoring official flood warnings, utilizing online mapping tools, watching for visual signs of rising water, and having an emergency action plan are all key ways residents can keep informed and stay safe when flooding threatens their neighborhood. Paying attention to flood forecasts, having supplies ready to go, and taking preventative measures to protect your home are also essential to being prepared. Staying one step ahead of flood dangers can help minimize costly damage and prevent potential loss of life.
