A cluster of thunderstorms off the Carolina coast is associated with an old frontal zone and an upper-level trough. This feature will slowly shift offshore and it will take some time to develop.
A strung out tropical wave in the Caribbean is positioned from near 83 west and 15 north to near 73 west and 20 north. It is generally tracking west at 15 knots, although the eastern end of the wave is heading more to the northwest across Hispaniola. This wave is causing several showers and thunderstorms over this area with the heavier rainfall over Haiti into Jamaica and eastern Cuba. This system is becoming more and more elongated with time and will split with one piece moving northwest and the other moving due west. Development of either split looks unlikely, but the west moving system could gather some strength with low shear over the region.
We continue to track an impressive tropical wave centered near 55 west and 13 north. It is moving to the west-northwest at about 15 knots and has a center of circulation that can be seen on a visible satellite loop. It is causing plenty of thunderstorms near the center of circulation and looks like a tropical depression already. However, African Dust to the north of the wave and some east-northeast shear aloft may be keeping this feature from developing more robustly. Shear conditions will be less than favorable for the day, but could turn more favorable as the wave heads into the Caribbean. This wave has become less organized in the last 12 hours, but still contains moderate shower and thunderstorm activity. A robust tropical wave in the eastern Atlantic is located along 23 west and south of 12 north and it is moving west at 15-20 knots. This system will head into a little shear on the south side.
