Tropical Storm Isaac lashes northern Caribbean

SAN JUAN, Puerto Rico (AP) - A new tropical storm -- named Joyce -- has formed in the eastern Atlantic. But it's no threat to land -- and the more immediate concern is Tropical Storm Isaac, which has already brought flooding to parts of Puerto Rico.
Forecasters say the storm is slowing down, and that will give it time to dump more rain on the island.
Isaac is churning up waves as high as 10 feet.
Forecasters say Isaac will likely turn into a Category 1 hurricane by tomorrow as it nears the Dominican Republic and Haiti. It's expected to weaken a little while heading over their island and Cuba, then possibly move on toward Florida as a hurricane by Monday.
