Meanwhile, to the east of that, a trough of low pressure located over the central tropical Atlantic continues to produce some disorganized showers and thunderstorms. This system is expected to move slowly west-northwestward, and some slow development is possible early next week as it approaches the Lesser Antilles. The chance of development remains low at 20% over the next five days.

It’s important to note that neither wave poses a threat to the United States over the next five days at this time.
