Reporters: Do you want to accompany a USGS crew as they work in the field to install storm-tide sensors before Hurricane Florence’s arrival?
If so, please contact John Shelton for NC and SC at 803-750-6112 or email@example.com
Hurricane response crews from the U.S. Geological Survey are installing storm-tide sensors at key locations along the North and South Carolina coasts in advance of Hurricane Florence. Under a mission assignment from the Federal Emergency Management Agency, the USGS plans to deploy about 160 sensors and is consulting with federal and state partners about the need for similar equipment for other areas along the mid-Atlantic coast.
Storm surge is among the most dangerous natural hazards unleashed by hurricanes, with the capacity to destroy homes and businesses, wipe out roads, bridges, water and sewer systems, and profoundly alter coastal landscapes. The USGS has experts on these hazards, state-of-the-science computer models for forecasting coastal change, and sophisticated equipment for monitoring actual flood and tide conditions.
The sensors being installed to measure Hurricane Florence’s storm tide are housed in vented steel pipes a few inches wide and about a foot long. They are being installed on bridges, piers, and other structures that have a good chance of surviving the storm. The information the sensors collect will help define the depth and duration of a storm surge, as well as the time of its arrival and retreat. That information will help public officials assess storm damage, discern between wind and flood damage, and improve computer models used to forecast future floods. Information on the storm-tide sensor deployment and the incoming data will be available on the USGS “Flood Event Viewer” at https://stn.wim.usgs.gov/FEV/#FlorenceSep2018.
In addition to storm-tide sensors, 25 rapid deployment gauges are being installed at critical locations that may be impacted by storm surge or floodwaters, but where the USGS does not have permanent streamgages. The USGS is coordinating with the National Weather Service, FEMA, and state and local agencies to put the rapid deployment gauges in places with the greatest need. These specialized gauges can be quickly installed on bridges to provide real-time information on water levels. They will augment a network of 231 streamgages in North Carolina and 112 streamgages in South Carolina that provide critical information to the National Weather Service, FEMA and other USGS partners involved in issuing flood and evacuation warnings and in coordinating emergency responses to communities.
The USGS studies the impacts of hurricanes and tropical storms to better understand potential impacts on coastal areas. Information provided through the sensor networks provides critical data for more accurate modeling and prediction capabilities and allows for improved structure designs and response for public safety.
As the USGS continues to take all appropriate preparedness and response actions in response to Hurricane Florence, those in the storm’s projected path can visit www.ready.gov or www.listo.gov for tips on creating emergency plans and putting together an emergency supply kit.
