Wave 3 (East of Lesser Antilles): Axis along 59W/60W (05N to 20N), moving West at 10–15 knots.
Some gradual development is possible for waves 1 and 2 during the early to middle part of next week while the systems move westward. Upper-level winds are expected to become much less conducive for development later in the week. NOAA NHC currently gives these waves a slight (20-30%) risk for developing into a tropical cyclone.
