HOUSTON (ICIS)--The US National Hurricane Center downgraded Isaac to tropical storm status as it continued to pound southern Louisiana on Wednesday.
Isaac made landfall as a hurricane on Tuesday, but was downgraded at 1400 hours Central Time (1900 hours GMT) with maximum sustained wind speeds of 70 miles/hour (113 km/hour), the National Hurricane Center said.
Wednesday marked the seventh anniversary of Hurricane Katrina, which devastated New Orleans.
Hurricane Katrina was much more powerful when it made landfall seven years ago.
Katrina was one of the most devastating hurricanes in the history of the US, killing about 1,200 people and causing about $75bn (€60bn) in damage in the New Orleans area and along the Mississippi coast, the hurricane centre said.
No US deaths had been reported as a result of Isaac.
Before reaching Louisiana, Katrina had sustained wind speeds of 175 miles/hour, but by the time it made landfall, it had maximum winds at 120 miles/hour.
