Here's an image that shows infrared satellite data in grays, and the strength of the Saharan Air Layer (SAL) in yellows-reds. Once the disturbance gets out closer to the Lesser Antilles, the SAL is barely present, and the environment is more moist. Using an average speed of 5°/day, the wave should be moving out of the dry air by Friday morning.

|Track forecasts from 3 global and 3 regional models (06Z runs). For reference, 120 hours from this run would be valid early Tuesday morning. (B.Tang at UAlbany.)|
|Tracks of all tropical cyclones that passed within 100 miles of where the easterly wave is centered today during July and August (1851-2013). The Cat3+ ones that turned toward the north are David 1979, Betsy 1965, and Unnamed 1893.|
