This is entirely incorrect, the tops for this storm according to jep FD pro (airline EFB) and foreflight where both indicating 40-50k in altitude, also hurricanes while they do have largely horizontal winds, what do you think causes the heavy eye will precipitation and thunderstorm like behavior? Exactly what causes a thunderstorm, low pressure, slow isobaric lapse rate. EMPHASIS ON LOW PRESSURE. Low pressure causes the up/down drafts you speak of since less dense hot air rises incredibly quickly. Realistically what happened here is the radar picture for Flightradar24 is not entirely accurate as to what the precip was at that point in time and space.

Ahh I see, my mistake have a nice day :)

I have absolutely no idea what your on about, the eye is about 5 nm away from the projected track…

Your correct about a headwind which makes it more probable that my point is correct in which the radar data is just lagging behind the current flight tracks since (can’t speak for nks dispatch) but other US 121 carriers wont approve such a strong headwind like flying through a hurricane, much less the associated up/down draft projections.

Sure maybe my comment is redundant because I (checks notes) added more context about meteorology than what the other commenter said???

Also I know for a fact that it’s just a delayed NEXRAD projection because FR24 literally says it takes 30 minutes for weather refreshes to occur ( in there blog), this being more than enough time for the spirit to only be penetrating the southern edges of the storm and not actually coming so close to the eye center, thus giving the plane a tailwind, which would be approved.
