Tropical Storm Marco

The Gulf Coast is now preparing for what could be a major hurricane to hit later this week

Tropical Storm Laura flooded neighborhoods with knee-deep water and brought power outages to Haiti Sunday. Warm, deep Gulf waters are expected to strengthen Laura, potentially turning it into a hurricane near Louisiana or Texas.

The Gulf Coast is on edge with two tropical storms churning toward the shoreline. The first, Marco, is expected to make landfall Monday afternoon in south Louisiana. The second strike will come just a couple of days later, and forecasters warn Laura could be a major hurricane by the time it reaches the shore.

Hurricane Marco has weakened to a tropical storm in the Gulf of Mexico as closes in on the Louisiana coast, while Tropical Storm Laura has killed at least 11 people in the Dominican Republic and Haiti.
