EPAC: BUD - Post-Tropical

[Yellow Evan]

Bud's CDO is shrinking. Seems to be having dry air problems. I suppose it's possible this has peaked already.

I think even if it doesn't strengthen further, it should at least maintain its strength for another day or so while conditions remain favourable.

The perfect shot.

The eye is looking better defined now.

Looks like it's about to get an embedded white ring set up. Once eye clears out I expect to see a T6.0 Cat 4.

Hurricane Bud Discussion Number 9
NWS National Hurricane Center Miami FL EP032018
300 PM MDT Mon Jun 11 2018

The organization of the cloud pattern has improved overall, but the
eye has been fluctuating between clear and obscure. An average of
TAFB/SAB subjective T-numbers and much higher objective values from
UW/CIMSS yield an initial intensity of 105 kt. Bud still has the
opportunity to gain some additional strength during the next 12
hours or so before the environmental conditions become less
conducive and the cyclone gradually encounters the cooler waters
near the Baja California peninsula in about 3 days. By then, Bud is
expected to be below hurricane strength. The official intensity
forecast is in between the Corrected Consensus HCCA model, which
weakens Bud fast, and the SHIPS guidance which shows a more gradual
decay.

Bud appears to be moving toward the northwest or 315 degrees at
about 6 kt. The steering pattern is well established while Bud
continues to be embedded within the flow around a subtropical
ridge centered over Mexico and the southwestern United States. Once
Bud reaches the southwestern edge of the ridge in about 24 to 36
hours, it should gradually turn north-northwestward and then
northward toward the Baja California peninsula. The NHC forecast is
not different from the previous one and is in the middle of
the guidance envelope. It is also a little to the west of the
HCCA corrected consensus and the FSSE, which are among the rightmost
of the models.

Bud looks much better now. Nice B ring with an OW that is slowly becoming circular. If it keeps up, this will be a Category 4 in a short order.

[Ntxw]

This is the best he has looked all day. I'd say now worthy of at least 115kts

[aperson]

Every time convection wraps to the same part of the SW quad there's significant lift. It's been happening repeatedly since hot towers started firing in the CDO pattern last night. Neat feature, not sure what it means.

[Visioen]

My computer screen is becoming too small.

[SouthDadeFish]

This is the best Bud has ever looked. Very impressive for June.

[TheAustinMan]

Attaboy. That's a nice clear eye that Bud has right now.

Eye clearing out on visible:



Let's see how much the numbers go up if/when the eye completely clears out. Because SAB is lagging behind the rest, constraints may limit its estimates. NHC will likely need to rely on ADT and TAFB if we want to see a cat.5.

[Ubuntwo]

Eye clearing out.

[aperson]

Last few frames are showing cloud tops in the ring warming without any nearby convection forcing subsidence. I think it's either leveled off or started weakening slightly, but this could easily be a bit of reorganization. Still looks like a solid T6.0 Cat 4 that would be underestimated a bit due to cirrus in the eye.

Inner core fluctuating by the hour.
