Sea birds surround the American Legion fishing pier in Bay St. Louis, Miss., as Isaac’s winds and storm surge flood some low laying neighborhoods, Wednesday, Aug. 29, 2012, the seventh anniversary of Hurricane Katrina hitting the Gulf Coast. Isaac was packing 80 mph winds, making it a Category 1 hurricane. It came ashore early Tuesday near the mouth of the Mississippi River, driving a wall of water nearly 11 feet high inland and soaking a neck of land that stretches into the Gulf. (AP Photo/Rogelio V.

Hurricane Isaac crashed ashore in southeast Louisiana on Tuesday, bringing high winds and heavy rain.
Nearly 70,000 people in Louisiana were without electricity.
On Tuesday, some parts of Louisiana’s low-lying Plaquemines Parish were already flooded.
The effects of the large, slow moving storm have already been felt along the coast lines of Louisiana, Mississippi and Alabama.
Large storm surge caused flood in Louisiana and winds gusted to 99.7793 kilometers per hour (62 miles per hour) in New Orleans.
On Tuesday morning, engineers closed the new floodgate at Lake Borgne, east of New Orleans, for the first time.
It is largest storm-surge barrier in the world.
Hurricane Isaac is predicted to hit New Orleans almost exactly seven years after Hurricane Katrina hit New Orleans on August 29, 2005 killing more than 1,800 people and causing billions of dollars of damage.
People were urged to leave the low-lying areas in Mississippi, Alabama and Louisiana because the hurricane could flood towns and cities in, with a storm surge of up to 12 feet high!
Before turning into a hurricane, Tropical Storm Issac had already killed at least 23 people in Haiti and the Dominican Republic.
Tropical Storm Debby is moving slowly to the Florida coast on Sunday, June 24.
This brings strong winds and waves that forced the closure of about a quarter of offshore oil and gas production in the Gulf of Mexico.
Several Alabama beaches were closed due to rough surf.
According to an emergency management official, earlier on Sunday, it caused tornadoes that killed a woman, severely injured a child and wrecked homes in central Florida in rural Highlands County.
The National Hurricane Center maintained a storm warning for the Mississippi-Alabama border, extended warnings for Florida’s northwest coast to Englewood, and discontinued warnings for the Louisiana coast.
Residents were warned to expect storm conditions within 36 hours.
