Hurricane Isaac made landfall in Louisiana late Tuesday and early Wednesday as a Category 1 hurricane and began a slow push toward New Orleans. The storm has already overpowered a levee in Plaquemines Parish, south of New Orleans, and more than 400,000 people near New Orleans have lost power. Through it all, the storm is being documented via social media. We'll bring you the latest news and photos of Isaac from Twitter, Facebook and Instagram.
