The Invest storms are far from bogus. They are tropical waves that appear to have the potential to develop into tropical depressions, storms, or hurricanes.
Avid weatherwatchers follow them closely, as does the the National Hurricane Center. An Invest is something they spend time and manpower investigating with flights to gather atmospheric conditions.
A new Invest, 93L, was identified last night, and the huge wave coming off Africa right now is almost certain to become Invest 94L within a day or two.
They don't actually give a storm a name until it reaches tropical storm status. It has to be identified as a tropical depression before that and just given a different number. If Invest 92L becomes a tropical depression, it will be called TD8.
Being able to track these Invests on Earth Google thanks to your work is just awesome, in my opinion.
