New JMA H5 winter maps from NE forum post: this is what it appears to me that the maps are showing DJF: strong +PNA, ~neutral EPO, -AO, ~neutral NAO Dec: slight +PNA, ~neutral EPO, slight -AO to neutral AO, slight +NAO Jan: strong +PNA, ~neutral EPO, -AO, ~neutral NAO Does anyone disagree with my opinion on what these maps are showing for these indices?

The last 10 days of the PDO have had a decent rise overall though nothing extreme:

Thanks. Whereas for TCL they’ve got a TS warning, they didn’t ever predict TS conditions for ATL. Instead they have a high wind warning:

The main issue some of us have is the double standard of concern in Tuscaloosa vs virtually no concern in ATL (at least earlier…maybe this will change). The forecasted conditions for during the GT/Duke game in ATL Sat. afternoon are far worse than those for even the tailgating period (6 hrs before kickoff) in Tuscaloosa. Furthermore, the forecast for ATL is actually quite a big deal, which along with thunderstorm chances has a high wind warning and thus would be far worse than the typical breeziness of a Miller A:

The point some of us have been making is the double standard being applied regarding the concern for the attendees in Tuscaloosa vs that for those in Atlanta: Tuscaloosa: SATURDAY TROPICAL STORM CONDITIONS POSSIBLE. SHOWERS, COOLER WITH HIGHS IN THE MID 70S. NORTHEAST WINDS 25 TO 30 MPH WITH GUSTS UP TO 45 MPH, BECOMING SOUTH 10 TO 15 MPH WITH GUSTS UP TO 30 MPH IN THE AFTERNOON. CHANCE OF RAIN NEAR 100 PERCENT. Atlanta: SATURDAY SHOWERS. A SLIGHT CHANCE OF THUNDERSTORMS IN THE MORNING, THEN A CHANCE OF THUNDERSTORMS IN THE AFTERNOON. BREEZY WITH HIGHS IN THE LOWER 70S. EAST WINDS 15 TO 25 MPH WITH GUSTS UP TO 50 MPH. CHANCE OF RAIN NEAR 100 PERCENT. ————— As one can see, the forecast is actually much worse for the afternoon gametime in ATL for Duke/GT than it is not just for the evening gametime in Tuscaloosa but even during the tailgating time in Tuscaloosa well before the game even starts! So, gusts to 50 with possible thunderstorms/heavy rain and even a slight chance for a tornado in ATL for the game itself vs gusts only to 30, much lighter rain, and no thunderstorms in Tuscaloosa during the entire PM tailgating period well before the game even starts! @PhiEaglesfan712@vortex95

For those who didn’t realize it, 1905’s very late 1st on record H was similarly powerful to Isaias with it peaking as a MH (cat 3) and that was also during El Niño. *Edited: it was not the last storm of the season at genesis but was when it degenerated below TC status at its end.

ATL’s looking worse right now at Duke/GT gametime than Tuscaloosa’s looking even during most of afternoon well before kickoff. Why with all of the warranted concern for GA/AL are the media hardly, if any, talking about any concern about Duke-Georgia Tech in ATL? Can you explain this double standard? Well, I realize way more interest and of course $ are involved with GA/AL, but that’s beside the point of concern about human beings wherever they are.

So, with all of the talk about the safety of folks in Tuscaloosa for GA/FL (which I agree is warranted), why doesn’t the media seem to care much about the safety of folks going to Bobby Dodd Sat afternoon, which will likely have worse conditions than Tuscaloosa in the mid to late afternoon (gametime in ATL) because worst conditions at Tuscaloosa should end by early afternoon. This is such a silly/stupid double standard. —————— FFC’s not playing around: .FLOOD WATCH IN EFFECT FROM LATE FRIDAY NIGHT THROUGH SUNDAY MORNING... ...HIGH WIND WATCH IN EFFECT FROM SATURDAY MORNING THROUGH SUNDAY MORNING... —————— SATURDAY SHOWERS. A SLIGHT CHANCE OF THUNDERSTORMS IN THE MORNING, THEN A CHANCE OF THUNDERSTORMS IN THE AFTERNOON. BREEZY WITH HIGHS IN THE UPPER 60S. EAST WINDS 20 TO 25 MPH WITH GUSTS UP TO 50 MPH. CHANCE OF RAIN NEAR 100 PERCENT.

Josh is in Pensacola as he chose Isaias over Simon but wishes there were two of him so they could chase both lol: https://x.com/iCyclone/status/2108365382130045125

I cannot overemphasize how important what I bolded above is. This idea is well explained at the link below, which I recently posted: Significant Increase in Sea Surface Temperature at the Genesis of Tropical Mesoscale Convective Systems Using satellite observations and a high-resolution global climate model, we show that this threshold has undergone a significant warming trend during the past several decades and will continue to increase in the future. This warming trend is closely related to the changes in the tropical mean SST. A constant relationship between the SST threshold and upper-tropospheric temperature is found in both the current climate and a warming climate, which corroborates the argument that tropospheric temperatures in the tropics approximately follow a moist adiabatic adjustment. https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2022GL101950

That’s good news if it holds for those threatened. Hopefully shear will do its thing and keep it struggling. But it looks like it will probably still be a hurricane when it comes in and thus be no picnic for them.

Do you have it for OK?

Technically according to this image, it was a H by 0Z on 10/8 in 1905 or 7PM EST on 10/7. So, that means 2026 was a little later if you go by this:

No, it’s the latest 1st H since 1851, inclusive. That’s the first year of these tracks at the NHC site.

Yeah although 1905 was about as late:
