Tropical Storm Bret Strengthens and Moves into Caribbean, NHC Tracking.

Tropical Storm Bret is expected to strengthen and move into the Caribbean near St. Lucia by early Friday morning, but the threat of it becoming a hurricane is diminishing. The storm is predicted to weaken as it moves south of Puerto Rico, sparing the island. Another system behind Bret has a 70% chance of strengthening to a named storm, which would be Cindy. The National Oceanic and Atmospheric Administration predicts up to 17 named storms and nine hurricanes this year.
