Isaac makes landfall in Louisiana
Hurricane Isaac made landfall in the US state of Louisiana, bringing high winds, soaking rains and posing the first test for the costly flood-protection system built after the devastation of Hurricane Katrina that killed over 18,000 people in 2005.
Isaac, a vast storm that tore through southeastern Louisiana on the anniversary of Hurricane Katrina, weakened from a hurricane to a tropical storm after pushing floodwaters over a levee in marshy Plaquemines Parish and forcing the dramatic rescue of dozens of stranded residents.
