Description of the event

A Category 1 hurricane hit New Orleans on Tuesday, bringing torrential rain and force-winds to the Gulf Coast. As winds dropped below 75mph, the hurricane downgraded to Tropical Storm Isaac despite expecting another 24 inches of rainfall.

The flooding impacted Braithwaite and Louisiana the most where 75 people including their pets were rescued while another 25 still remain on rooftops.

The Tropical Storm Isaac killed 23 people in Haiti and the Dominican Republic before heading towards the Gulf Coast.

Isaac struck on Tuesday with winds up to 80mph passing through Mississippi, Alabama and Louisiana. The storm came seven years after Hurricane Katrina devastated the Gulf Coast, killing nearly 2,000 people.

Plaquemines Parish, just 60 miles southwest of New Orleans, collected flood water topping a nine-foot-high flood bank causing 2,000 residents to be evacuated from the area. No deaths or injuries were reported.

More than 4,000 U.S. Army National Guard Troops are stationed across New Orleans, working alongside police, fire-fighters and rescue-operations. The troops visited several homes ensuring that there were no deaths or injuries.

A dusk-till-dawn curfew has been imposed as the storm continues and will remain in place until further notice.

Since the storm, 725,000 people across five states remain without power; leaving some without for a week.

U.S. President Barak Obama issued emergency declarations for Louisiana and Mississippi states.

Whilst highways, roads and homes remain swamped, search-and-rescue operations will resume in heavily flooded areas.
