Floodwater swimming

Joshua Keegan and his dog Scout swim in the rising water of Lake Pontchartrain on Aug. 28, just hours before Isaac makes landfall in New Orleans.


After reaching hurricane status several hours before hitting land, Isaac reverted to a tropical storm the following afternoon. Officials urged residents to evacuate or stay indoors for the duration of the storm, which rolled in almost exactly 7 years after Hurricane Katrina devastated the Big Easy in 2005.

Shelter from the storm

Claude Jones, 61, rests on a folding cot on Aug. 29 inside a high school gymnasium in the low-lying New Orleans suburb of Belle Chasse, La.


Although Isaac's strength has lessened considerably since being downgraded to a tropical storm, it continues very slowly northwestward. The sluggish pace, which is caused by the lack of jet streams in the region, makes it difficult for cities to carry out relief operations.

Isaac's aftermath

The storm downed numerous trees, knocked out power to hundreds of thousands of homes and caused extensive flooding in several low-lying towns in Plaquemines Parish.
