That isn’t exactly missing - more like sideswiping
Yes, that is the “hand off” that Bernie Rayno Chief Meteorologist for Accuweather was talking about-— that time period when the LOW to the SW of the storm— separates from it and no longer drawing it West. The orange dipping down band represents the Low to the NE North bunched up against a large Midwest High convergance-— creating the “trough” that picks up and draws the storm North.
If this happens faster than the model— ie. if Dorian hasn’t crossed the longitude of Andros Island in the Bahamas- it could skip FL altogether. Tons of rain and tidal things in any case all the way up.
BTW Joe Bastardi of Weather Bell Analytics can be heard talking about the strange anomaly of the projected “hand off” of the upper level low seen in the Euro model but not the GFS— and called it “strange” and not understandable in the projection. These all being computer projections. Pointed this out last Saturday on his free 14 minute weatherbell.com summary video at the bottom of the page.
Something made him change his mind from the noaa nhc forecast— because as Bernie Rayno says== “actions are being taken, costly massive human actions, on the basis of these projected paths”. For example— if somehow the “handoff “does not occur and Dorian tracks S-SW into the Lower Keys— without prior evacuation-— just monster horrible result.
One more— the US Navy knows whats going on. Mayport in JAX full fleet in port egress to sea— go out past Bermuda and then come back in 3 or 4 days. That was this AM... they are leaving.
