Coastal Change Hazards Team Forecasted Hurricane Beryl Beach Impacts
As Hurricane Beryl approached the US Gulf of Mexico coast, the USGS Coastal Change Hazards team produced a series of forecasts for impacts on the beach. Forecasts were updated daily based on wave and storm surge forecasts from the National Oceanic and Atmospheric Administration (NOAA).
Prior to landfall on the Texas coast on July 8, 2024, the Coastal Change Hazards Team predicted that 53 percent of beaches were very likely to erode at the dunes’ base, 21 percent of dunes were very likely to be overwashed by storm waves, and 3 percent of dunes were expected to be very likely to be inundated (completely submerged) by surge, tide, and waves given worst-case scenario surge and timing of the storm. In addition to special forecasts focused on impacts at the peak of the storm, real-time forecasts were being updated in the Total Water Level and Coastal Change Forecast Viewer. Beyond informing the public, the forecast results were being used to determine placement of water level (pressure) sensors for USGS real-time response to Hurricane Beryl. After landfall of a storm, the Coastal Change Hazards team uses NOAA imagery, USGS CoastCams, other beach cams, Digital Elevation Models (DEMs) constructed from post-storm aerial imagery and lidar data, and observations from USGS sensors to validate the predictions. The USGS Coastal Change Forecast model is used to estimate the impacts of elevated waves and storm surge along the coast due to extreme storms. This model has been in use since 2011 and is continually updated and improved.
