At either 250hPa (34,000ft) or 500hPa (18,400ft) you can see mid-level airflows that seem to be at work preventing Irma taking a more Westerly track, with some evidence even apparent down at 700hPa (10,000ft). Not saying they’re 100% of the reason for the change in heading, but certainly appear to be contributing. An interesting piece to a very large puzzle.
Euro has the wobbles settling down to direct eye center hits on Key West, west tip, Ft Myers, then Tampa.
If true, it needs to turn more yet.
You have different numbers here. First of explain the Pa.
You have 250 at 34,000. You have 500 at 18,400 and 700 at 18,000.
For a layman you will need to explain that difference between
500 and 700.
