MYRTLE BEACH, S.C. (WMBF) - The odds of both Laura and Marco developing by the end of the week continues to increase.

It’s important to note that any impact to the US is highly uncertain at this time. Stay updated with us for the latest changes.

System #1

A tropical wave located over the eastern Caribbean Sea is producing disorganized showers and thunderstorms, along with gusty winds in these thunderstorms. Some gradual development of this system is possible over next day or so while it moves westward at about 15 to 20 mph across the central Caribbean Sea. After that time, the wave is forecast to move more slowly west-northwestward, and a tropical depression is likely to form late this week or this weekend when the system reaches the northwestern Caribbean Sea.

Invest 97L has a 40% chance of development over the next two days and a 80% chance of development over the next five days.

System #2

An elongated area of low pressure, located a little over 1000 miles east of the Windward Islands continues to produce a concentrated area of showers and thunderstorms mainly on the west side of the disturbance. Environmental conditions are conducive for further development, and a tropical depression is expected to form during the next day or two while the system moves generally west-northwestward at 15 to 20 mph across the central and western portions of the tropical Atlantic.

Invest 98L has the highest chance of development over the next two and five days at 90%.

System #3

A large area of showers and thunderstorms, located over Guinea and Sierra-Leone, Africa, is associated with a vigorous tropical wave. Environmental conditions are expected to be marginally conducive for some development of this system while the wave enters the extreme eastern Atlantic on Friday. By early next week, however, conditions are forecast to become less favorable for tropical cyclone formation while it moves west-northwestward at 15 to 20 mph toward the central tropical Atlantic.

We are watching a cluster of thunderstorms move off the African coast. This will turn into our next chance to watch for development within the next week or two.
