High of 93.7 yesterday. Honestly I thought we were done with this

I don;t understand the physics of how Humberto kicks the other system into the east coast.

If you’re on the coast from Florida to NC I would be following this closely and make sure you have the ability to prepare if needed. This forecast is as uncertain as it gets relating to a tropical cyclone

I said this yesterday and it holds just as true today but what a crazy TC setup. Some of these model solutions don’t even seem possible with twin strong hurricanes dancing around each other. EPS is concerning as are hurricane models but that being said given the proximity to Humberto, j wouldn’t put stock in ANYTHING until we have a coc and even then the evolution of Humberto will be critical

I have 0.11" storm total so far. Hopefully CTP is correct in their big finale forecast this morning Sent from my SM-G970U1 using Tapatalk

Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 AM EDT Thu Sep 25 2025 Eastern Caribbean Sea (AL94): A tropical wave centered near the Dominican Republic continues to produces widespread disorganized showers and thunderstorms. The wave is expected to move west-northwestward around 10 to 15 mph, spreading heavy rainfall and gusty winds across Puerto Rico and the Dominican Republic through today. The system is then expected to slow down and turn northwestward when it reaches the southwestern Atlantic. A tropical depression is likely to form when the disturbance is in the vicinity of the Bahamas late this week. Interests in Puerto Rico, the Dominican Republic, Haiti, the Turks and Caicos Islands, and the Bahamas should monitor the progress of this system. * Formation chance through 48 hours...medium...50 percent. * Formation chance through 7 days...high...80 percent.

The 0Z EPS is by far the most ominous for the SE US (including some that get into the Gulf) with a whopping ~75% of the members hitting or skimming. Some of these are very weak (not full TCs) while ~1/3 of the hits are strong.

0Z Euro, just like the 0Z CMC, hits Georgetown, SC, on Monday evening (probably because it was further N than Humberto) though it isn’t as strong as the CMC (989 mb per WxBell): So, of major 0Z ops, Euro and CMC hit Georgetown while UKMET, GFS, and Icon stay well offshore.

I still think 980 mb is pretty strong, and the outflow of 94L would be dominating against Humberto.

I saw that sub-4980dm made it to land about a week ago. I know August broke the record over the arctic circle for lowest heights on record, but then we did it again a week later! That one however, stuck around a little while and moved south over northern Russia sub-4980dm. Impressive for what was Summertime. This +AO phase has been running strong since the Northern Lights made it south in May 2024. September 2025 will probably make it 7 straight +AO months [CPC].

EPO patterns, both positive and negative, typically happen in only 8-14 day cycles. This is different from the PNA and NAO, which can run in 15-45 day cycles. +15 days after an EPO event actually has a slight opposite correlation to its previous phase, overall (only -0.03 though).

Today/tonight's rain, which was the highest chance/flood hazard day, is a flop. It didn't rain enough to wet the road under trees here. There may be more upstream but we'll see how heavy it actually is.

But the 0Z GFS has 94L no stronger than the high 980s while it has Humberto ~25 mb stronger (~963 mb). Were you aware of that? So, considering that, wouldn’t it make sense for Humberto to dominate?

I am skeptical of the GFS showing a strengthening dangerous hurricane over the Bahamas suddenly being sucked into Humberto. If it were just a wave, sure...but if 94L is a well established hurricane by that time, I highly doubt that it just gets sucked away.

0Z GEFS: the most threatening run yet to the SE US (even more than 18Z):

I meant how fast it decreases at airports after it is initially reported.

Before taste of Fall wx comes into STX at the end of this week, looks pretty interesting overnight into Thursday with the cool front crawling through the region. Already near 4 in. rainfall just in the past 2 hours right over the Choke Canyon reservoir under a very decent storm cluster looking at storm totals on CRP radar. In the region near SAT where the drought is still the worst in the entire state. PWs as usual this time of year down here pooling > 2 in. ahead of the front. But H5 flow is about 30 knots now, west-northwest on VWP. So starting to see better storm organization and more frequent lightning and even a few powerful +CGs (>100 Kiloamps) on lightning data across the region. Wouldn't rule out a few embedded transient supercells and several inches of rainfall spots overnight with decent mid-upper level support for September standards. Only severe caveat that's been a fairly common TX theme this year (even before summer) is once again, meager ML lapse rates. 'Though, Euro seems to be under-doing them a bit lately.

1. 0Z CMC Georgetown, SC hit with 975 mb H as not as strong Humberto (983 mb) doesn’t dominate: 2. 0Z GFS is safely OTS with Fujiwara from Humberto.

Rained a quarter inch in the morning through noon. The morning forecast underestimated the system. But it had been so dry the rain was soaked up quickly and the event was fine to be held. It was hot and humid until the sun went down and then cooled off nicely. .

0Z Icon: Humberto pulls 94L ESE to keep it safely away:

Raining nicely here, a bit of lightning and thunder. Enjoyable! 0.30" in the last hour.

Finally getting heavy rain

0.95" Didn't think I would see much of anything here until tomorrow.

No surprise but officially expected to become our next major now. Tropical Storm Humberto Discussion Number 2 NWS National Hurricane Center Miami FL AL082025 1100 PM AST Wed Sep 24 2025 The cloud pattern of Humberto has changed little in organization over the past several hours. Some rudimentary convective banding features are evident but the cold cloud tops are rather fragmented at this time. Upper-level outflow is being restricted over the western portion of the circulation, at least partially due to the outflow from disturbance 94L located near Puerto Rico. The current intensity estimate is set at 40 kt in agreement with a recently received scatterometer pass. The storm center is not yet very well-defined so the initial motion is a rather uncertain 300/10 kt. Over the next few days, Humberto should be steered generally west-northwestward to northwestward on the southwestern side of a subtropical mid-level high pressure area. The steering scenario for the tropical cyclone will likely become more complicated in 2-3 days due to the interaction with the developing system 94L to the west. The official forecast track is quite similar to the previous one, and roughly in the middle of the guidance. However, due to the likely complications in the evolution of the steering flow, there is lower than normal confidence in this track forecast. Global models suggest that there will be some relaxation in westerly vertical wind shear over Humberto in the coming days. This, along with very warm ocean waters and a moist mid-level air mass, should lead to strengthening. The system will probably become a hurricane in a couple of days, and then strengthen into a major hurricane. The official intensity forecast is in reasonable agreement with the simple and corrected model consensus, including the latest FSU Superensemble forecast.
