NHC Lifts Atlantic Wave’s Development Odds to 60% as Saharan Dust Slows Near-Term Growth

A tropical depression could form by mid to late week with model tracks split between a recurvature offshore or a route nearer the northeast Caribbean.

Overview

  • The disturbance is near the Cabo Verde Islands and moving west to west-northwest at 10–15 mph, with the National Hurricane Center giving it a medium 60% chance of development over seven days and near 0% in the next two days.
  • Forecasters expect slow organization through the weekend due to dry Saharan air and a relatively cool patch off Africa, with more favorable conditions possible by Tuesday or Wednesday.
  • Computer guidance generally supports gradual development, though solutions diverge later on steering, which lowers confidence in any specific track.
  • Analysts note low odds of a short‑term land threat, and any potential effects on the northeast Caribbean would not occur before next weekend on the current timetable.
  • The Atlantic remains quieter than average at peak season with six named storms and one hurricane so far, while separate outlooks highlight the Central American Gyre for possible homegrown development later in September.
