Tropical Storm Kiko developed early Sunday and is expected to become a hurricane later this week, according to the U.S. National Hurricane Center in Miami. The hurricane center did not issue any coastal watches or warnings.

“Strengthening is expected during the next couple of days, and the system is forecast to become a hurricane by Tuesday,” the hurricane center said.
