PROJECT ALERT NOTICE (AL LA MS) Hurricane Isacc storm surge

Date: Wed, 29 Aug 2012 16:31:06 EDT

Summary: Monitoring sites characterize Isacc storm surge

USGS crews from several states in the Southeast have deployed about 170 sensors to record storm surge along the coast of LA, MS, and AL. Most of the information will not be available until the sensors are recovered and processed a few days after the storm. The effort will provide valuable data for future storm surge modeling and prediction. The character of the Hurrican Isaac storm surge can be monitored at this site near the west end of the Mississippi Sound.

In addition to the magnitude of the wind-driven water level increase the viewer can observe a significant increase in specific conductance which is evidence that the source of the water is the open Gulf, where specific conductance values are typically above 40000, rather than local runoff.

This effort is in support of FEMAs mission in addition to the USGS Hazard and Water Missions.
