Please take a few minutes to do the Hurricanes Milton and Helene High-Water Mark Survey
The CHNEP is gathering time-sensitive water level data from Hurricanes Milton and Helene. It is critical to document this information in order to improve future storm surge and flood forecasting. We are asking you to collect and report high water marks in your area from Milton and/or Helene ASAP to help create a publicly available map of water levels during each hurricane to understand how they affected our region.
Water marks disappear quickly, so time is of the essence! Each entry should take only 1-2 minutes. All you need is a measuring tape and your cell phone (with location services turned on) to contribute to this effort! Scan the QR code or click on the Survey button below to input your data!
