Summary: Louisiana WSC Tropical Storm Isaac Update for August 28, 2012

Tropical Storm Isacc is expected to continue moving northwest at 7 mph for the next couple days. Maximum sustained winds are near 70 mph, and are anticipated to strenghen to a hurricane status later today. Storm surge in Souteast Louisiana and Mississippi is projected to be between 6 to 12 feet. Rainfall amounts are likely to exceed 10" as Isacc slows down after landfall.

The USGS has deployed 93 storm-tide sensors with another 20-30 sensors planned for deployment today. The La WSC is working on decoding and displaying the rapid deployment gage data on NWIS-WEB. Furthermore, La WSC is running VRS RTK levels today. We will be using the LSU Geoinformatics GULFNET system and establish datums at many these gages.

Many of the gages within the Breton Sound Basin are currently showing the storm surge of approximately 4 feet:
