Hurricane Isaac was a slow-moving tropical cyclone that caused severe damage along the northern Gulf Coast of the United States in late-August 2012. Isaac reached hurricane strength the morning of August 28. The storm made its first U.S. landfall at 6:45 p.m. CDT that evening (2345 UTC), near the mouth of the Mississippi River. As it passed through the northern Caribbean, around south Florida, and into Louisiana and the Middle Mississippi Valley, Hurricane Isaac brought lots of rain, some of it beneficial, and some of it not. It is having an impact across all of the eastern US. In some places, it a flood nightmare and in some places it helps relive local droughts.
