(CNN) -- After churning through the Caribbean and chugging up the Gulf of Mexico, Hurricane Isaac made landfall over southeastern Louisiana on Tuesday night -- bringing with it sustained winds of 80 mph and torrential, stinging rains. According to the National Hurricane Center, the storm's center moved over land in Plaquemines Parish at 6:45 p.m. (7:45 p.m. ET) -- one day before the seventh anniversary of Hurricane Katrina, which left nearly 1,800 dead and caused billions of dollars worth of damage along the Gulf Coast. Isaac's eye then "wobbled westward" and moved back over Gulf waters, and by 10 p.m. CT was centered about 75 miles southeast of Houma, Louisiana -- all while keeping its strength as it lashed those onshore.
