Each one these blue dots represents a site where a storm-tide sensor bracket has been installed for the Gulf of Mexico pre-defined network. There are currently 85 brackets in Florida, 6 in Alabama, 3 in Mississippi, 18 in Louisiana and 26 in Texas, for a total of 138 bracketed sites. (Not all brackets will be used in all storms.)

The Snake River is the largest tributary of the Columbia River. It drains over 108,000 square miles in mainly Idaho and portions of Montana, Nevada, Oregon, Washington, and Wyoming. The climate of much of the Snake River watershed is arid or semi-arid and spring snowmelt contributes substantially to the river’s flow.
