Isaac weakens as it hits New Orleans

  • Hurricane Isaac weakened to a tropical storm on Wednesday as it lashed the city of New Orleans.

    Isaac hit the US Gulf Coast exactly seven years after the much stronger Hurricane Katrina.

    At 4pm local time, the storm was 35 miles south of Baton Rouge and 60 miles west of New Orleans, according to the US National Hurricane Center (NHC).

    The storm, moving at about 6 mph, is expected to take most of the day to travel to Baton Rouge, located 70 miles to the north west of New Orleans.

    Rainfall of up to 1ft 8in is expected across wide areas along with the likelihood of isolated tornadoes along the coast.

    Earlier this week, Isaac killed around 24 people as it passed over Haiti and the Dominican Republic.

    It caused significant flooding and damage across the Caribbean and forced the start of the Republican party's convention in Tampa, Florida to be delayed by a day.
