Innovative Flood Mapping Technology Helps Communities Prepare for Storms
ASHEVILLE, N.C. — In the days leading up to the storm named Helene, forecasters described its projected impacts with serious terms such as “devastating” and “catastrophic.” While these words convey the potential dangers, they can only do so much to prepare communities for what lies ahead.
Fortunately, new technology from the National Oceanic and Atmospheric Administration (NOAA) is stepping in to help. This technology not only communicates flood risks more effectively but also provides a clear visual representation of these risks.
Monica Youngman, Chief Scientist for NOAA’s National Weather Service, has been at the forefront of improving community preparedness since the Helene incident. Youngman noted the gap in awareness among residents, saying, “Our forecasters were warning of catastrophic impacts 48 hours before the event, yet I heard from many neighbors who were unaware it was coming. That really struck me.”
One of the innovative tools being used is called Flood Inundation Mapping (FIM). This technology provides a better picture of what communities might face during flooding events. Youngman explained, “For example, the FIM shows what Biltmore Village looked like during Helene. Imagine if we could have visualized how it would look beforehand.”
This mapping system combines three-dimensional visuals with crucial infrastructure information—like the locations of water treatment plants, power substations, highways, hospitals, and schools. Youngman remarked, “By providing these important 3-D images to communities, we can help make daunting forecasts feel more real and accessible.”
The Flood Inundation Mapping service aims to ensure that all communities are warned as early as possible about the extent of rising waters. Additionally, a new tool called “Cascading Impacts” will help translate future flood forecasts into localized effects on infrastructure and identify who might be affected.
“With this data, we can prepare communities more effectively, save lives, and provide timely support to those in danger,” said Youngman.
The National Weather Service actively collaborates with emergency managers, first responders, media, and federal agencies to enhance disaster readiness. Youngman stressed the importance of gathering more data from weather observation networks worldwide to build on these efforts and improve prediction models.
This advancement in flood mapping technology promises to give communities a clearer idea of what they may face, leading to better preparation and more effective responses during emergencies.
