As Hurricane Isaac weakened to a tropical storm but continued to unleash heavy rain, winds and a dangerous storm surge along the northern Gulf Coast, authorities said they would breach a levee in flooded Plaquemines Parish to try to relieve pressure.
But weather conditions were too severe to try it Wednesday, Coastal Protection and Restoration Authority head Garret Graves told the Associated Press. It was unclear how quickly authorities could get needed equipment to the site, south of New Orleans.
Isaac came ashore Tuesday night with 80-mph winds and driving rain in the parish, where levees have yet to be reinforced after 2005’s catastrophic Hurricane Katrina. In New Orleans, where the flood-control system has mostly been upgraded, levees were holding.
In Plaquemines, at least 118 people were rescued, including 25 trapped on their roofs or in their attics as water rose 14 feet, Reuters reported. Animals were rescued too, including about 15 dogs, a cat in a cage, even a fawn.
