The tropical disturbance that had rolled off the coast of Africa yesterday has now been designated as Invest 90L. This system has very good cyclonic turning but the one thing that 90L has a problem with is that it is embedded within the ITCZ. Â It will be very difficult to develop within the ITCZ as it has to compete with the surrounding convection along with the rest of the atmospheric conditions. Once it breaks free of the ITCZ and can maintain the convection on its own then there is good chance it will develop other wise it will just be stormy weather in South America. I do feel that 90L will break it self away from the ITCZ and models do think this may develop. The initialization of the models run are new and might have some bias in them.
Some may wonder why is the Invest number 90L instead of 100L. The invests start off with 90 and end at 99. Once 99L is used they return back to 90L.
