A large area of unsettled showers and thunderstorms in the Easter Caribbean will continue moving west and may eventually become a tropical cyclone. The system is in the “slow cooker”, and intensification into a tropical cyclone is unlikely by midweek. By late week, however, the conditions may become more conducive to development as the disturbance moves to near the Bahamas.
