WEST PALM BEACH, Fla. — The disturbance formerly known as Potential Tropical Cyclone 9 has strengthened into Tropical Storm Isaias (ees-ah-EE-ahs) bringing flooding to Puerto Rico and other islands.

At 11 p.m., the system is moving west-northwest at about 20 mph with maximum sustained winds near 50 mph.

SPECIAL SECTION: Hurricane Guide

On the forecast track, the system will pass south of Puerto Rico on Wednesday night, near or over Hispaniola on Thursday and near eastern Cuba and the southeastern Bahamas on Friday.

The system will approach the northwestern Bahamas and southern Florida Friday night.

When the system moves toward Hispaniola, it will be run into rugged mountains, which may limit strengthening.

By the weekend, it will approach Florida. Still, there is uncertainty as to the exact track of the storm, considering there's no real center of circulation, so models aren't able to initialize properly.

Computer models show about a 50 percent of West Palm Beach seeing tropical storm-force winds.
