It has been exactly two years since a hurricane has made landfall in the state of Louisiana.
On August 28, 2012 around 6:45pm, Hurricane Isaac came ashore near the mouth of the Mississippi River with maximum sustained winds of 80mph and a minimum central pressure of 965mb.
While the storm was a category one hurricane, geographically it was expansive, creating widespread impacts due to storm surge, heavy rain and wind.
The highest observed surge was in Shell Beach, Louisiana where a gauge rose 11.03 feet above normal tide levels. Parts of Plaquemines and St. Bernard Parishes were inundated with storm tide more than 10 feet above ground level. Higher waters likely occurred in uninhabited areas within the Federal Levee System.
Most of extreme Southeastern Louisiana experienced over 10" of rainfall causing many reports of flash flooding. 20.66" of rain was recorded in New Orleans. The Tangipahoa River at Robert crested 9.0' above flood stage. Baton Rouge received roughly 6" of rain due to the storm.
17 tornadoes were spawned by Isaac within the United States, with one EF-2 reported in Mississippi.
In the United States, 5 deaths were attributed to Isaac-one in Louisiana. A 75-year old Slidell man drowned when his car plummeted off of an I-10 on-ramp into a roadside ditch filled with 9 feet of water.
The United States damage estimate for Hurricane Isaac came out to $2.35 billion. Specifically in Louisiana, about 59,000 homes were damaged by Isaac and the storm cut power for 901,000 residences-47% of the state's power customers. 90% of the Louisiana's sugarcane crop was damaged.
