Tropical Storm Melissa is lumbering through the Caribbean Sea and bringing a risk of dangerous landslides and life-threatening flooding to Jamaica and southern Hispaniola.

Tropical Storm Melissa is effectively parked in the central Caribbean, dumping devastating amounts of rain on Haiti and Jamaica that has already claimed at least three lives and destroyed one bridge. And more rain is on the way.

The National Hurricane Center in Miami warned of "life-threatening and catastrophic flash flooding and landslides" throughout Hispaniola.
