Hurricane Isaac damages could hit $1.5 billion

Hurricane Isaac’s slow, rainy march through Louisiana is expected to cause as much as $1.5 billion in insured losses, according to one disaster modeling firm. While comparatively modest as hurricanes go, Hurricane Isaac is already wreaking havoc. More than 644,000 were without power in Louisiana, Mississippi, Alabama and Arkansas, power companies told CNN. And some 100 residents had been or were in the process of being rescued from flooded homes and rooftops in coastal Plaquemines Parish, according to CNN affiliate WWL.
