168 ish more miles to go. It's currently about 105 miles west of St Pete.  9h20min until landfall at the current speed and its 10:40.  So around 7-8am edt depending if it speeds up.

Do we agree that land, particularly in the formation it's heading to, tightens up the storm?  Or is that just something I heard once from JB.

Do not know if it tightens up the storm, but the curvature doesn’t help alleviate the storm surge.

Seems a little weak and early for an ERC - wxtwitter is abuzz with speculation due to these bands.  To me its just spirally still.

That would be landfall here

Gusts for these are in the 20-30kt range.  High tide varies, but basically between midnight and 2am. When does the surge threat pass? The storm is already west of these areas, I suppose the wind shift to the west isn't going to help. Edit: if you read the warnings it says through Thursday morning

Some spots still expected to flood

With it being at 960mb at last update. It's worth noting that models are initiating mostly at 980's mb for same time frame. Is that a trend that sticks? If so, not good news.

930's-40's I think is a real possibility.

Agreed.

I don’t pretend to be a hurricane expert, but from my experience the ones that are rapidly intensifying as they make landfall end up being some of the hardest hitters. Not a good trend.

Not good at all. Terrible trend towards these types of storms the past couple of years

I believe there is an issue with global deterministic models and their ability to resolve initial MSLP w/respect to tropical cyclones. I'll either verify or disprove this when I get to work in 5 hours but this storm does mean business!

Yep. 8th major hurricane in GOM since 2017, which is insane!  Of those 8, only one has been weaker then Category 4 if this one pans out.

Putting in the coordinates to Google and merging them on my phone to the best of my limited availability shows this… where it is in the gulf and where they’re predicting the landfall.

So the skeptic in me believes the center will still make landfall west of the projected path … unless some serious eastward movement starts soon…. Based just on my own observations of past track and the limited time/distance remaining til landfall.  White dashed line is where I’ve seen it going since passing west of Captiva.  White straight line is where it would have to go to hit the predicted landfall.

Coldest cloud tops we’ve seen in a while where those lightning strikes occurred.  Definite signs of strengthening again.
