Monitoring Inland Storm Tide and Flooding from 

Hurricane Irene along the Atlantic Coast of the 

United States, August 2011

By Brian E. McCallum, Jaime A. Painter, and Eric R. Frantz

The U.S. Geological Survey (USGS) deployed a 

temporary monitoring network of water-level sensors at 

212 locations along the Atlantic coast from South Carolina 

to Maine during August 2011 to record the timing, areal 

extent, and magnitude of inland hurricane storm tide and 

coastal flooding generated by Hurricane Irene (table 1; fig. 1). 

Water-level sensor locations were selected to augment existing 

tide-gage networks to ensure adequate monitoring in areas 

forecasted to have substantial storm tide. As defined by the 

National Oceanic and Atmospheric Administration (NOAA; 

2011a,b), storm tide is the water-level rise generated by a 

coastal storm as a result of the combination of storm surge 

and astronomical tide.

Hurricane Irene initially made landfall on the coast 

of North Carolina near Beaufort on August 27, 2011, as a 

category 1 hurricane on the Saffir-Simpson hurricane scale 

(National Hurricane Center, 2010), and after traversing the 

coast and Outer Banks of North Carolina, the storm went 

back out to sea and made a second landfall as a category 1 

hurricane near Atlantic City, New Jersey, on August 28. Of 

the 212 locations monitored, 202 sensors recorded a storm 

tide. Three water-level sensors were lost or malfunctioned 

during the storm, and five sensors did not record storm tide 

because of either a lack of water-level rise above astronomical 

tide or a storm tide lower than the elevation of the sensor. 

A typical storm tide sensor installation is shown in 

figure 2. At the 202 locations, these sensors were programmed 

to record water pressure at a 30-second interval, which was 

converted to water level in feet above the North American 

Vertical Datum of 1988 (NAVD 88). In addition, 75 of the 

202 sites included a sensor to record barometric pressure at 

a 30-second interval, expressed in pounds per square inch. 

Water-level elevation and barometric pressure were recorded 

over time by the sensors during the storm, as shown by the 

example graph for a single location in figure 3. A high-water 

mark (HWM) was flagged and surveyed near each sensor in 

order to verify the peak value recorded by the sensor. Eight 

additional locations were instrumented with rapid deployment 

gages, which were real-time water-level sensors that recorded 

water-level elevations every 15 minutes and updated hourly 

to USGS Web pages (table 1; fig. 4). Lastly, wave height was 

measured every 2 seconds at two locations near the mouth of 

Chesapeake Bay near Norfolk, Virginia. The total number of 

sensors deployed in each State are shown in table 1.

Data were collected and processed following protocols 

established by McGee and others (2005), which includes 

correcting water pressure for changes in barometric pressure 

and salinity. Quality-control checks were made by (1) colocating water-level sensors at a subset of sites and comparing 

data from those sensors to water levels computed from 

recorded pressure data at the sites, and (2) comparing water 

levels computed from recorded pressure data to water levels 

recorded at nearby USGS streamgages in addition to nearby 

high-water marks, to the extent possible. In the aftermath of 

the storm, an additional 137 independent high-water mark 

locations were surveyed in relation to NAVD 88; 104 locations 

in North Carolina, 14 locations in New York and 19 locations 

in Virginia. Elevation surveys using survey-grade global positioning systems (fig. 5) and differential levels were conducted 

to relate all water-level data, HWM data, reference marks, new 

benchmarks, and sensor measuring points to NAVD 88.

The data from the Hurricane Irene storm-tide network 

constitute an extensive collection of continuous water-level 

records that document a single land-falling hurricane. The data 

can be used to evaluate the performance of storm-tide models 

for (1) maximum and incremental water level, (2) flood 

extent, and (3) site-specific effects of storm tide on natural and 

anthropogenic elements of the environment. The data from 

the temporarily deployed sensors are considered approved, 

while the streamgage or tidal gage data are being made 

available on a provisional basis becauase they are subject to 

the USGS annual data report approval process. All data are 

presented in tab-delineated, ASCII format for each sensor 

location by using a USGS interactive storm-tide mapper Web 

application available at http://wim.usgs.gov/stormtidemapper/

Digital photographs of select locations also are available 

from the interactive mapper. Data for each sensor include 

location, date, time, water level, and barometric pressure and 

the data-processing date is provided in the file header. Data 

files for HWMs include location, type and quality of the mark, 

and elevation. The interactive mapper also includes waveheight data collected in collaboration with the North Carolina 

Sea Grant and The University of North Carolina, Institute of 

Marine Sciences.

A list of the 212 temporarily deployed storm-tide sensor 

locations and the peak storm-tide elevation recorded by each 

sensor are provided in table 2. Data-collection sites were 

categorized as surge, riverine, or wave height with respect 

to the interval of data collected and the site proximity to the 

coast. Riverine sites can be influenced by upstream runoff 

from inland flooding. Permanent monitoring network data 

at 80 locations that are operated by the USGS and were 

augmented by the temporary sensors are provided in table 3 

and 46 locations that are operated by NOAA are provided in 

table 4. Additional NOAA water-level and meteorological 

data for Hurricane Irene that include affected areas outside the 

USGS deployment region were released recently by Fanelli 

and Fanelli (2011). A listing of the additional HWM data 

collected and surveyed following the passage of Hurricane 

Irene are presented in table 5.

Engineers. The data in this report are the result of tireless 

hours by numerous staff in USGS Water Science Centers 

in South Carolina, North Carolina, Virginia, Maryland, 

Delaware, New Jersey, New York, Connecticut, Rhode Island, 

Massachusetts, New Hampshire, Maine, and Georgia. The 

authors would like to particularly highlight the leadership and 

dedication of USGS employees in North Carolina, Virginia, 

and Maryland in delivering valuable data to numerous 

stakeholders in a very timely and accurate manner.
