Storm-tide sensors installed along North Carolina coast ahead of Dorian
Scientists are installing sensors to measure the flood damage and erosion Hurricane Dorian could leave behind.
U.S. Geological Survey scientists are installing at least 150 storm-tide sensors and at least 22 other instruments that will track the hurricane's effects along the coasts of North and South Carolina.
Field crews have installed 70 sensors in South Carolina and 90 in North Carolina.
Most of the instruments are designed to measure the height and duration of the storm-tide as the storm approaches shore, makes landfall and then moves off the coast. Others will monitor water levels on bodies of water inland.
If there is flooding, crews will make real-time measurements and these records will help FEMA target emergency relief to the hardest-hit areas.
