Original story:

Rain and showers associated with a northern cold front are just the beginning of wet weather rolling over the Cayman Islands this weekend. A tropical system off the coast of northeastern Nicaragua became more concentrated and showed greater likelihood of development as it moved north.

The U.S National Hurricane Center advised Friday morning that the system had a 60 percent chance of becoming a tropical depression or storm by Sunday, when a second cold front will make conditions less favorable.

Conditions are expected to be conducive for development as the system moves over the Cayman Islands and into the northwestern Caribbean. Once the system moves north of Cuba, increasing upper-level winds will make conditions less favorable.

Residents of the Cayman Islands, central and western Cuba and Jamaica are advised to expect locally heavy rainfall.

Scattered showers and heavy rains, associated with the first cold front, continued to pour down over the islands Friday morning. The Cayman Islands National Weather Service advised that flooding may occur in low-lying areas. Small crafts should exercise caution over open waters. Rough seas and waves reaching 6 feet are expected throughout the day.

An Air Force Reserve reconnaissance aircraft was scheduled to investigate the tropical system Friday afternoon, if necessary. The next named storm of the Atlantic hurricane season is Philippe.
