WASHINGTON, Aug. 29 (Xinhua) -- Hurricane Isaac weakened to a tropical storm on Wednesday afternoon with storm surge and inland flooding still threatening, said the U.S. National Hurricane Center on the 7th anniversary of Hurricane Katrina's destructive arrival.
The U.S. National Hurricane Center said Tropical Storm Isaac is currently moving on at 6 mph (9.7 kph), with the maximum sustained wind of 70mph (113 kph), and centered about 50 miles (80.5 kilometers) southwest of New Orleans, Louisiana.
But the center warned life-threatening hazards from storm surge and inland flooding still remained.
Although Isaac was much weaker than Katrina, forecasters said the current slow movement and the large size of Isaac could cause hours longer impact on residents living along its path.
Isaac has
lashed1 heavy rains and winds to the state of Louisiana since it made landfall in southeastern U.S. state late Tuesday as a Category One Hurricane.
Early Wednesday, a storm surge has topped a levee in Plaquemines Parish south of New Orleans, the largest city of Louisiana and most-
devastated2 area seven years ago by Hurricane Katrina.
Local officials said they had been working with U.S. Coast Guard to rescue people
stranded3 on top of the levee, and they may have to
breach4 the levee in the flooded area.
Utility companies said more than 500,000 people were left without power across Alabama, Louisiana and Mississippi.
The weather condition will persist through Wednesday night or early Thursday, said Richard Knabb, director of the National Hurricane Center.
Dozens of families that had ignored
mandatory5 evacuation orders in a low-lying area had to retreat to roofs and sought rescue amid fierce wind and
slashing6 rains, the CNN reported.
The southern U.S. states of Florida, Louisiana, Mississippi and Alabama have been on high alert against the threat of Isaac. Thousands of residents living in Louisiana, Mississippi and Alabama were told to leave their
coastal7 houses since Monday.
Earlier Wednesday, U.S. President Barack Obama called Governors of Alabama, Mississippi and Louisiana as well as Mayor of New Orleans, pledging that the federal government was ready to provide local officials with necessary support and resources needed. He also acknowledged the 7th anniversary of Hurricane Katrina provides of the
lasting8 effects these types of storms can have on communities.
Wednesday marks the 7th anniversary of Hurricane Katrina, which devastated New Orleans and the
Gulf9 Coast on Aug. 29, 2005. The hurricane was the
costliest10 natural disaster, and one of the five deadliest hurricanes, in the history of the United States. At least 1,836 people died and total property damage was estimated at 81 billion U.S. dollars.
A day earlier, Obama warned residents living alongside the expected path of Isaac of significant flooding and other damages. He urged them to
evacuate11 in time to safe grounds.
Also, Florida, Louisiana and Alabama have already declared states of emergency over the weekend, fearing that Isaac might repeat the disaster that Hurricane Katrina brought to the Gulf coast just seven years ago.
