Looks like a predecessor rain event perhaps on the euro?

No posts from ineedfish.. all you need to know

Euro looks fun. Gfs looks boring. At least we have something interesting to track!

My opinion has not changed. I don’t care what the models say. I still believe we finish this season below 100 ACE. If I’m wrong so be it

I had foolishly allowed myself to believe that we were actually done with 70-degree dewpoints for the year, and there was even reason to hope that the Atlantic would be devoid of tropical systems except far-off fish storms. Suddenly it all comes crashing down!

Where’s the heavy rain and storms? I just ran in no rain

I smell a bust

Here are some snow stats for I95 cities. Last 10 years have been below normal at all cities. Philly to Boston are above average over last 30 years. This year 95/96 will be dropped from 30-year average, so 30-year averages are likely to drop.

Been a while since rain like this.

It doesn't, last night's run of the Euro has a stronger blocking high over Humberto slowing it down and allowing 94L to be pulled into the coast by the ULL. Without Humberto 94L would have a higher chance of landfall

NNE soaker Enroute.

TriPol, Humberto doesn't kick so much as the other system escapes. Deepmind 18z suggests the position of 94L relative to Humberto, once 94L reaches about Nassau, is the key to its landfall prospects. At 26-27°N, if it's a little faster and north of due west from Humberto, some members reach SC as early as Monday night. Slower members get no farther than 28°N (about Cape Canaveral's latitude) before getting sucked toward Humberto and OTS. To my eye, it looked like a 50/50 split. Here's my take: if Humberto becomes a major east of the Bahamas, and it moderately scoots NW while growing in size, whatever 94L becomes after getting over Hispanola is gonna put on some brakes due to Fujiwhara. That's why I don't see the low making a CONUS landfall in the cards; for us in the SE U.S., the effects are then limited to coastal erosion from the two systems and maybe several inches for whoever sits along the Carolina coasts nearest the low as it gets yoinked east.

I'll take the 3K and HRRR please.

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. Forecaster Bucci

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).
