Why 12 and not 10

[chadtm80]

From the discussion

The NWS rules governing the naming of tropical cyclones specify
that...within a basin...when a cyclone forms from the remnant of a
previously existing cyclone...the old name/number is retained.
Tropical Depression Twelve has a complex genesis that likely
includes a mid-level remnant of former Tropical Depression Ten. A
review of satellite and rawinsonde data over the past week or so
suggests that a second disturbance approached and combined with the
mid-level remnant of Tropical Depression Ten on 20 August. Because
it is impossible to determine which of these two systems is
associated with today's genesis...we have elected to use the
designation twelve rather than ten for the new depression. This
situation differs from last year's regeneration of Ivan...in which
the low-level remnant of that system remained a distinct feature
that could be followed continuously until it regenerated.

They went with 12, because I said that a TC over Arizona had a better chance of developing than did xTD10. So technically I was right, but I think 10 played at least some part in it. I had to send a Vermont Teddy bear to the NHC, but it was money well spent.

Isn't Stewart great? He always seems to have the best discussions and provides insights and explanations we don't seem to get elsewhere.

I really appreciate his service!

Yeah, I like him. I'd say he's one of my favorites. Meanwhile, Franklin keeps babbling on about how every named storm is the earliest for that letter on record. Can you say, duh?

Those are so cute!

The forecaster, not the storm?
