A vigorous and fairly sizable wave rolling off the westernmost tip of Africa this morning has the interest of many models. Conditions for development this week and into next are much better than encountered by recent waves which attempted to get going within the monsoon trof in the central-east Tropical Atlantic (see Lounge).

As of the August 3, 2017 2AM TWO, NHC has assigned 50-50 odds that this wave becomes a tropical cyclone within 5 days. It is worth noting that forecast environmental conditions suggest that this feature could become a long-track hurricane. Movement is likely to be west or west-northwest at 10 to 15 mph for the next several days.
