Hurricane Matthew's Water Footprint

Hurricane Matthew's impact on precipitation and streamflow Map of Hurricane Matthew's water footprint Legend Inches per hour (county average precip) 0 to 0.1 0.1 to 0.2 0.2 to 0.3 0.3 to 0.4 0.4 to 0.5 0.5 to 0.6 0.6 to 0.7 0.7 to 0.8 > 0.8 Hurricane Matthew USGS stream gage USGS stream gage discharge
Hurricane Matthew approached the southeastern U.S. coast on October 7, 2016. In the map above, the hurricane’s impact on precipitation and streamflow are shown. Normalized discharge (cubic feet per second) at a selection of US Geological Survey gaging stations within ~200 km of the eye of the hurricane is shown in the right panel. Variation in the shape of the hydrographs (right panel) is due to stream size, storm-surge, reservoir closures, and other local conditions, which can impact the effect of precipitation on flow. Gages shown do not include the US Geological Survey Short-Term Network gages deployed to capture more detailed effects of the hurricane ( http://stn.wim.usgs.gov/fev/#MatthewOctober2016 ).

Data Sources

Streamflow: U.S. Geological Survey National Water Information System (http://waterdata.usgs.gov/nwis). Time series of discharge at selected gages within ~200 km of the eye of the storm are shown through time, ordered by latitude and normalized to site-specific maximum discharge observed over the duration of the hurricane.

Precipitation: National Weather Service Environmental Modeling Center National Center for Environmental Prediction Stage IV precipitation analysis (http://www.emc.ncep.noaa.gov/mmb/ylin/pcpanl/stage4/), aggregated according to Blodgett (2013, http://pubs.usgs.gov/fs/2013/3035/pdf/fs2013-3035.pdf)
