Hurricane Dennis dealt a glancing blow to the Florida Keys on Saturday, knocking out power and leaving streets flooded with seaweed as it roared toward the storm-weary Gulf Coast, where nearly 1.4 million people were under evacuation orders.
The hurricane, blamed for at least 20 deaths in Haiti and Cuba, carried a threat of more than a half-foot of rain plus waves and storm surge that could be more than a story high when it makes landfall Sunday somewhere along the coast of the Florida Panhandle, Alabama or Mississippi.
