Byrne, Sr., and Mark R. Dickman Abstract Hurricane Irma skirted the northern coasts of the U.S. Virgin Islands and Puerto Rico, with maximum sustained winds of 185 miles per hour (mi/h) on September 6, 2017. The hurricane first made landfall in Florida near Cudjoe Key, in the lower Florida Keys, with maximum sustained winds of 130 mi/h on September 10, 2017. The hurricane made a second Florida landfall on Marco Island, Florida, with maximum sustained winds of 115 mi/h on September 10, 2017. The U.S. Geological Survey (USGS), in cooperation with Federal Emergency Management Agency, deployed a temporary monitoring network of water-level and barometric pressure sensors at 249 locations along the Puerto Rico, Florida, Georgia, and South Carolina coasts to record the timing, areal extent, and magnitude of hurricane storm tide and coastal flooding generated by the hurricane. Immediately following the passage of Hurricane Irma, the sensors were retrieved, and the data were disseminated on the USGS Flood Event Viewer (https://stn.wim.usgs.gov/FEV/#IrmaSeptember2017). The storm-tide peak data values were verified by comparing data from hydrologic recorders and nearby high-water marks (HWMs). Following the hurricane, 508 independent HWM locations were flagged and surveyed relative to the North American Vertical Datum of 1988, National Geodetic Vertical Datum of 1929, or a local datum along the southeastern U.S. coast, and to Puerto Rico Vertical Datum of 2002 in Puerto Rico. Most HWMs were in Florida because of the path of the hurricane. The data from the Hurricane Irma storm-tide network are available on a provisional basis in tab-delimited, American Standard Code for Information Interchange (ASCII) format and Network Common Data Form (NetCDF) format by site for each sensor by using the USGS Flood Event Viewer. Introduction Hurricane Irma skirted the northern coast of the U.S. Virgin Islands and Puerto Rico as a Category 5 hurricane on the Saffir-Simpson scale (National Weather Service, 1972), with maximum sustained winds of 185 miles per hour (mi/h) on September 6, 2017 (fig. 1). The hurricane first made landfall near Cudjoe Key, in the lower Florida Keys, as a Category 4 hurricane with maximum sustained winds of 130 mi/h on September 10, 2017 (National Hurricane Center, 2017). The hurricane made a second landfall on Marco Island, Florida, as a Category 3 hurricane with maximum sustained winds of 115 mi/h on September 10, 2017 (National Hurricane Center, 2017). The hurricane left 23 percent of Puerto Rico (370,000 customers) and 59 percent of Florida (6.1 million customers) without power (U.S. Department of Energy, 2017). The U.S. Geological Survey (USGS), in cooperation with the Federal Emergency Management Agency, deployed a temporary monitoring network of water-level and barometric pressure sensors at 249 locations along the Puerto Rico, Florida, Georgia, and South Carolina coasts to record the timing, areal extent, and magnitude of hurricane storm tide and coastal flooding generated by Hurricane Irma (fig. 2). Storm tide, as defined by the National Oceanic and Atmospheric Administration (2013), is the water-level rise generated by a combination of storm surge and the astronomical tide during a coastal storm. Storm surge is defined as the water-level rise, caused by a storm, over and above the predicted astronomical tide. The deployment of water-level and barometric pressure sensors and subsequent high-water mark (HWM) collection were completed as part of a coordinated Federal emergency response as outlined by the Robert T. Stafford Disaster Relief and Emergency Assistance Act (42 USC §5121 et seq.) under a directed mission assignment by the Federal Emergency Management Agency. In addition to the pressure sensors, a total of 508 HWMs were recovered and surveyed following the techniques described in Koenig and others (2016). During the hurricane, real-time water-level data collected at temporary rapid deployment gages (RDGs, https://water.usgs.gov/hif/programs/projects/rapid_ deployment_gage_III/), long-term USGS streamgaging stations (https://waterdata.usgs.gov/nwis) with instrumentation used to measure water level and corresponding streamflow, and tide-gage stations were relayed hourly or more frequently, through satellite telemetry, for display on the Flood Event 2    Monitoring Storm Tide and Flooding From Hurricane Irma Along the U.S. Virgin Islands, Puerto Rico . . .                                      90˚ 80˚ 70˚ 60˚ 50˚ 50˚ 40˚ 40˚ 30˚ 30˚ 20˚ 20˚ 10˚ 10˚ 0˚ 0 200 400 600 800 MILES 0 200 400 600 800 MILES Map area Puerto Rico U.S. Virgin Islands   FLORIDA Marco Island Cudjoe Key Florida Keys GULF OF MEXICO GULF OF MEXICO ATLANTIC OCEAN ATLANTIC OCEAN        EXPLANATION Storm category Tropical depression Tropical storm Category 1 Category 2 Category 3 Category 4 Category 5 Figure 1.  Hurricane Irma path and intensity, September 2017.

Viewer (https://stn.wim.usgs.gov/FEV/#IrmaSeptember2017). These real-time data provided emergency managers and responders with critical information for identifying flood- affected areas and accurately directing assistance to affected communities. Data collected during and following this hurricane and others (Frantz and others, 2017) can be used to calibrate and evaluate the performance of storm-tide models used to predict the maximum and incremental water level and flood extent and the site-specific effects of storm tide on natural and anthropogenic features of the environment. Hurricane Irma Storm-Tide Monitoring Water-level sensors were placed at sites selected to augment existing streamgage and tidal-gage networks to ensure adequate monitoring in areas forecast to have had substantive storm tide. A total of 215 water-level sensors, 12 wave-height sensors, 22 RDGs, and 73 barometric pressure sensors were deployed at 249 locations during September 4–10 before hurricane landfall (fig. 2; table 1). Six water-level sensors were lost, and 38 sensors did not record water level because of low water level or equipment malfunction. A typical sensor installation is shown in figure 3. The sensors recorded water-level elevations in feet above the North American Vertical Datum of 1988 (NAVD 88) or the Puerto Rico Vertical Datum of 2002 (PRVD02). Water-level sensors recorded data at 30-second intervals and wave-height sensors recorded data at 1-second or 0.25-second intervals. The barometric pressure transducers recorded barometric pressure, in pounds per square inch, at 30-second intervals. Water-level elevation and barometric pressure were recorded by the sensors during the hurricane, and an example of the data is shown in figure 4. The RDG water levels are mean values collected using a radar sensor sampling at 5-second or shorter intervals (Park and others, 2014) and averaged over 6 or 15 minutes. A typical RDG installation is shown in figure 5. Immediately following Hurricane Irma, the sensors were retrieved, and the data were disseminated on the USGS Flood Event Viewer. Data were collected and processed following protocols established by McGee and others (2006) Table 1.  Number of sites equipped to monitor Hurricane Irma storm tide, by State and U.S. territory.

The filtered storm-tide peak, as shown in figure 4 was determined using the method described by Frantz and others (2017). The storm-tide peak data values were verified by comparing adjacent hydrologic recorders and HWMs. Following the hurricane, 508 independent HWM locations were flagged and surveyed relative to NAVD 88, National Geodetic Vertical Datum of 1929 (NGVD 29), or a local datum along the Atlantic and Gulf coasts, and PRVD02 in Puerto Rico (fig. 6). Most HWMs were in Florida because of the path of the hurricane. Elevation Surveys National Geodetic Survey benchmarks throughout the study area were surveyed for vertical control. This control was established on permanent objects near the water-level sensors to relate the recorded water-surface elevation to the NAVD 88 or PRVD02 datum. Graduated steel tapes were used to relate the elevations of the reference points to those of the water-level sensors. Survey-grade Global Navigation Satellite System (GNSS) equipment (fig. 7) was used to determine the Elevation Surveys    5 Figure 4.  Hydrograph from Flood Event Viewer (https://stn.wim.usgs.gov/FEV/#IrmaSeptember2017) displaying storm-tide elevation and barometric pressure data recorded during Hurricane Irma at Goodland, Florida, September 2017.

All GNSS elevations in this report were derived using the GEOID12B model (National Geodetic Survey, 2017). Data Presentation The data from the Hurricane Irma storm-tide network are available on a provisional basis in tab-delimited, American Standard Code for Information Interchange (ASCII) format and Network Common Data Form (NetCDF) format by site for each sensor by using the USGS Flood Event Viewer. Digital photographs for selected locations are also available on the viewer. Data available for each sensor include location, date, time, water level, and barometric pressure. Data available for HWMs include location, description and quality of the mark, and elevation. The peak storm tide was recorded at a total of 205 water-level sensors (table 2, at the back of the report). Sites are categorized as storm tide or wave height depending on the data-collection interval and proximity to the ocean. For GNSS established elevations, the survey uncertainty of the recorded peak storm-tide is reported (table 2). The survey uncertainty was calculated using the methods described in Rydlund and Densmore (2012). The recorded peak storm-tide at the long-term USGS monitoring stations along the coasts of Puerto Rico, Florida, Georgia, and South Carolina is provided in table 3. In addition to the storm-tide data collected by the USGS, peak storm-tide elevations also were compiled for real-time monitoring stations operated by State and other Federal agencies (table 4). The North Carolina Division of Emergency Management provided data for three of their monitoring stations (David Herlong, North Carolina Division of Emergency Management, written commun., February 2017). Peak storm-tide data also were compiled for National Oceanic and Atmospheric Administration tide gages (https://tidesandcurrents.noaa.gov/stations. html?type=Water+Levels), which have instrumentation to measure coastal water level located in each State (National Oceanic and Atmospheric Administration, 2017) (table 4). All HWM data collected by the USGS immediately after Hurricane Irma are listed in table 5.
