Almost seven years ago to the day since Hurricane Katrina made landfall, a new hurricane came ashore on the Gulf Coast near New Orleans. While Hurricane Isaac has been much less intense than Katrina, it has caused serious damage, with heavy rains, storm surge, and winds of up to 100 miles per hour.
Hurricane Isaac comes at the end of a U.S. summer season filled with extreme weather events. From heat waves to droughts to wildfires, the United States has seen little in the way of relief from severe events over the last several months. In fact, the majority of the lower 48 states are still facing drought. While Isaac may relieve drought conditions in some areas of the country, recent forecasts from the Climate Prediction Center project drought conditions to continue through large parts of the country at least through November.
