What is an invest?

An invest is a naming convention officials use to identify areas they are investigating for possible development into a tropical depression or tropical storm within the next seven days. 

In the Atlantic, these systems and models are tagged as Invest 90L, Invest 91L, all the way up to Invest 99L, and then it starts back at 90L and repeats.
