Background pressures seem high due to the digging ridge. If Eta is below 910 mb, considering its small RMW, it's probably pushing 160 kts at the surface.

I looked at that for a minute but idk that's a fairly large gyre of low pressure in the SW Caribbean

My hands are going to fall off. This is more enthusiasm than the actual season prediction got.

Wow. Eta is definitely highlighting the problem with the CI number needing to be spooled in. ADTv9 has it clamped at 1.3T/6hr so it can't catch up with the raw value quickly enough.

No. This is an algorithm thing. Earlier for example it was capped at 0.7T/6hrs. Other times there are no constraints. CIMSS varies what rules they use based on a slew of decision trees (computer calculated).
