Presently, I'm thinking a peak of approximately 145 mph and 933 mb, with landfall at around 125 mph and 940 mb in the St. Marks area following an EWRC.
As always- this is my personal opinion, and NOT a forecast.

145-155 is my best guess.

In my opinion, Helene would likely develop into a high-end Cat 4, with a small chance of scraping Cat 5.

I'll say a 140 mph peak, 125 mph landfall, and it will bring low-end category 3 winds into Georgia.

This thing has monster potential.

145 mph, giant Category 4 beast. Pressure of 935 mbar.

I'm still going with 110-120kts but since the categories cutoff in this poll is right in the middle of this range I went ahead and went with the higher one. But I'll be surprised if it gets much higher than 120kts considering the shallow pressure gradient and broad wind field. Pressure would have to absolutely bomb to get winds that high.

I'm assuming an average deepening rate of 2 - 2.5 mb/hr for the next 15-ish hours until landfall. This would result in a pressure of 927 - 934 mb, I'll split it down the middle and go with 931 mb. Helene's winds are lagging behind the pressure a bit so instead of the Dvorak-related intensity of 130 kt, I'll go with 931mb/120-125 kt. For the poll this is right between two options, so I decided to be bullish since you have to take a chance sometimes and voted for 145 - 155 mph.

115-125mph. I'm thinking if this thing was gonna bomb out to a Cat 4 it would be further along by now. Still looking a bit ragged and not a whole lot of improvement on IR. Slow steady strengthening to Cat 3 by landfall

As a reminder this is just my opinion I'm not a professional.

Actually, no. The 11 out of 40 participants that chose 130-140 mph are operationally correct, while a case can still be argued that the 10 people who chose 145-155 may end up being correct if intensity is bumped in post-season analysis.

140mph/938mb was both the peak and landfalling intensity operationally. Post-season review has potential evidence for a bump up in windspeed as a drone that NOAA released just prior to landfall measured 158mph 10-second wind (not sure what that reduces to in 1-minute sustained winds).

I didn't know where to put this but Helene continues the trend of an major increase in landfalling CAT4+ hurricanes since 2017. Certainly for the US but basin-wide too. Even during the historic 2003-2005 period it was just Charley. Then before that it was Andrew!
