NATL: HUMBERTO - Remnants - Discussion

[Hurricane2022]

Where is the recon for this???

[StormWeather]

The third hurricane of the season. Below a part of 5 AM discussion.

Humberto has become better organized during the past several hours.
Conventional satellite imagery has shown a growing central dense
overcast, with hints of an eye-like feature near the center.
Microwave imagery revealed a well-defined rain band wrapping around
a vertically-aligned vortex, suggesting the developing of an
eyewall.

Two hurricanes within a week. Yep, the Atlantic has woken up for peak season alright.

…Late September is the new late August these past few seasons it seems

So far in 2024 and 2025 combined only 1 TC became a hurricane in the Aug 20 - Sep 20 period. In comparison, 8 TCs became hurricanes in the Sep 20 - Oct 20 period and note that it's only Sep 26 so far and this year is included in these statistics. So the stats will likely become even more extreme as the season continues. Incredibly anomalous hurricane formation so far these two seasons.

This is good news as the gulfstrean jet that samples the upper atmosphere went a few hours ago over Humberto and that data will feed the models. Now is flying in the 94L area.

Looks consistent with what I see on visible this morning, a somewhat large inner core for its size. I don’t think we’ll be getting an Erin-esque pinhole out of this one, but a larger core may strengthen its ability to fend off eyewall replacement cycles in the future.

The eye is slowly becoming visible (on VIS). Based on VIS and IR it'll most likely be quite a large eye.

[cheezyWXguy]

Wow, impressive strengthening trend taking place this morning. The eye is really starting to clear now.

Eye is definitely warming in recent frames even if UW-CIMSS ADT continues to miss it. Looks like it could be creeping up on Category 2 / T5.0 already.

I think that is very rapid organizing right there. At 5 this morning my time the core hadn’t full built itself yet and five hours later look at it.

Excuse me what!? I look away for like half an hour and now the eye is clearing out.

Are we about to see/currently seeing another RI?

[kevin]

Ehmm . I'm starting to rethink my cat 4 peak vote in the Humberto poll. This is already a cat 2 imo.

[sasha_B]

Eye temps are positive now. That cleared out shockingly quickly. (Incidentally, ADT has now registered Humberto's evident eye.)

NHC now forecasting a 125 kt peak. I was thinking earlier that I was too bullish in the poll calling for 135-145 kts for Humberto, but now I think I’m among the few who may end up being right in being bullish.

I understand that 1-min meso floaters have more uses than a storm not expected to threaten land, but I simply can't get enough of the 10-min imagery now - the changes are way too dramatic.

Within the past hour alone:
