A large tropical wave that just came off of Africa has been designated as Invest 99L. Although there isn’t much of any cyclonic turning, conditions are favorable for slow development. At the moment, the NHC is giving a 30% chance of becoming a tropical cyclone in within 48 hours. Most of the models are forecasting that Invest 99L will be turning NW and hopefully nothing we will ever have to worry about (unless you are a fish). This system has just been initialized and bias and errors are possible.
An update of ex-Gaston, conditions will be improving in the next few days and Gaston may regenerate. Gaston will be heading into an area where an anticylone will be over it which will allow strengthening to possible be a tropical storm in about 4 or 5 days.
