Flood Warning System: How Greater Houston Area Residents Can Sign Up for Free Flood Alerts
As storms move into the Houston region this weekend, local officials are encouraging residents across Harris County and beyond to take a simple step that could make a significant difference during severe weather: sign up for free flood alerts through the Harris County Flood Warning System.
The Harris County Flood Control District is reminding residents that staying informed during heavy rainfall and potential flooding events is one of the most effective ways to stay safe. By subscribing to alerts, homeowners, commuters, and families can receive near real-time notifications about rainfall and rising water levels across the county—information that can help people make informed decisions about travel, safety, and preparedness.
For many longtime Houston-area residents, flooding is not an abstract concern. The region’s geography and rapidly growing population make monitoring rainfall and waterways a critical part of daily life during storm season.
A Tool Designed to Help Residents Track Rainfall and Rising Water
The Harris County Flood Warning System (FWS) is a countywide monitoring network that tracks rainfall totals and water levels in bayous, creeks, and channels across the region. The system collects data from hundreds of monitoring stations and makes it available to both emergency responders and the public in near real time.
Residents can explore the system at harriscountyfws.org, where an interactive map allows users to monitor conditions across the county.
Using the Flood Warning System website, residents can:
- View current and historical rainfall totals
- Monitor water levels in channels throughout Harris County and beyond
- See a countywide snapshot of weather and flooding conditions
- Zoom in to specific neighborhoods, roadways, or waterways
- Click on gage stations to view charts showing current water levels and when flooding may occur
- Register for text or email alerts for locations important to them
These alerts can be customized to monitor areas near a home, school, workplace, or even along a daily commute.
For many residents, this type of real-time information provides peace of mind during storms while also helping them react quickly if conditions begin to change.

Free Rainfall and Water Level Alerts Delivered to Your Phone
One of the most widely used features of the Flood Warning System is its customizable alert service.
By registering through fwsalerts.org, users can subscribe to near real-time notifications when rainfall totals or water levels reach certain thresholds at specific monitoring stations.
These alerts can be delivered by text message or email, providing immediate updates when conditions change.
Emergency management officials say the alerts are particularly helpful during overnight storms or fast-moving weather systems, when flooding can develop quickly and residents may not be actively monitoring local conditions.
Protecting One of the Most Flood-Prone Regions in the Country
The Harris County Flood Control District oversees one of the most complex flood management systems in the United States. The agency manages more than 2,500 miles of channels, nearly 280 detention basins, and almost 12,000 acres of land dedicated to flood mitigation across Harris County.
Serving one of the nation’s largest and most flood-prone metropolitan areas, the district works to plan, build, and maintain infrastructure designed to reduce flooding risks while balancing community needs and environmental considerations.
Tools like the Flood Warning System are part of that larger effort—providing residents and emergency responders with critical data that helps communities respond more effectively when storms impact the region.
A Simple Step Toward Storm Preparedness
With rain expected across the Houston area this weekend, officials say now is the time for residents to become familiar with the Flood Warning System and set up alerts before severe weather arrives.
Residents can explore the interactive map and sign up for alerts at harriscountyfws.org, while a step-by-step registration guide is available at fwsalerts.org.
For families living near bayous, creeks, or flood-prone roadways, having access to real-time rainfall and water level information can provide valuable awareness during fast-changing storm conditions.
As hurricane season and spring storms approach, local officials emphasize that informed communities are safer communities.
