Scattered moderate showers and chance of isolated thunderstorms are forecast tonight, as a tropical wave and an upper level trough affect the islands. Showers are forecast to become more intense behind the wave which is around late tonight/early Thursday morning. Gusty winds will accompany these showers as well. Therefore, all residents and motorists in areas prone to flooding and landslides and near rivers and streams should exercise caution. Towards Friday, the upper level trough will move away from the vicinity, reducing the chance of showers and isolated thunderstorms.
