HURRICANE IRMA INFORMATION PORTAL
Hurricane María made landfall in Puerto Rico Wednesday morning as a strong category 4 hurricane, with winds of 155 mph that knocked out power for the entire island, and greatly impacted communication channels. Prior to the storm making landfall, USGS crews were out installing storm-tide sensors and maintaining streamgages critical to helping with flood forecasting. While many of the 108 USGS streamgages installed throughout the island continued to read and report water levels in rivers, canals and lakes via satellite, approximately 35 streamgages were damaged by the storm.
The storm-tide sensors, housed in vented steel pipes a few inches wide and about a foot long, were installed on bridges, piers, and other structures that have a good chance of surviving a storm surge during a hurricane. The information they 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.
