There are 2 distinct potential events on the op runs though- the initial one centered on the 19th and another one a couple days later with the boundary further southeast. The ens means depict the same idea. I'm not spending time poring over each ens member to try to further interpret wave timing, whether there might be 2 or 3 waves, or how amped they are at this juncture. All that will become clearer in time.
