MIAMI, Florida (AP) -- A tropical depression moved northwest across the Caribbean on Sunday, prompting storm warnings in Haiti and watches in Cuba and Jamaica, where it could bring more than 10 inches of rain, forecasters said.

The depression, the 16th of the Atlantic hurricane system, could strengthen into a tropical storm late Sunday, when it would be named 'Noel,' according to the National Hurricane Center.

A tropical storm warning was in effect for the southwestern peninsula of Haiti from the Haiti-Dominican Republic border westward to Port-au-Prince, meaning tropical storm conditions are expected within the next 24 hours.

The governments of Jamaica and Cuba issued tropical storm watches in their countries.
