Hurricane Ian

[MattPetrulli]

GFS sizably west

[Amped]

CMC started east of 12z but ended up a bit west by 84hrs

[CamSE-Wx]

JMA is also west on the 00z. Maybe a trend to watch there, we’ll see if the Euro bites in a bit

[NorthHillsWx]

GFS depicts a very small system north of Cuba 

[Normandy]

I am watching that giant curved band on the north side very closely.  Lots of motion in those cells suggesting that we might have large core developing.

Here's a late night Ian video for the night owls like myself

[Radtechwxman]

I think it's safe to say cores have aligned and are taking full advantage of high OHC and low shear environment right now. CDO exploding 

[GaWx]

0Z UKMET shifts back SE to Port Charlotte area of FL (ignore the lowball strengths as they've been low on every run. I watch mainly for the track changes). So, UKMET is a pretty decent right outlier, something it isn't accustomed to as more often it is on the left:

If west trend wins expect a weak system at landfall with flooding being the main issue

That suddenly made me hungry...but I'm at work tonight and cant cook shrimp lol

[HillsdaleMIWeather]

Has a nice comma look now

[WxSynopsisDavid]

Very healthy CDO with deep convection wrapping around the center. Ian is off to the races now

[Amped]

987.9 extrap, core has expanded a lot though.

[hawkeye_wx]

The new recon pass suggests the pressure is about the same as it was when the last plane left hours ago.

[hlcater]

New flight suggests only modest pressure falls over the past few hours. Though, notably, the storm's organizational structure has improved, with 50kt winds now showing up immediately SE of the center in what is likely a nascent inner core.

 

[WxSynopsisDavid]

Indeed we are seeing structure improvements and the pressure is steady now with minor pressure falls. Remember though, there is a lag between us seeing structure changes and the pressure actually tanking. By 5am we should see another significant pressure drop. It takes a few hours for the pressure to respond. It all does not happen at one time

[Snowlover11]

70mph at 2am

[GaWx]

0Z Euro 72 gets to just offshore Tampa and then barely moves north through 96 staying just offshore, a true nightmare scenario. Then it accelerates north to GA/FL border at 120.

[TradeWinds]

00z Euro looks to head directly for Tampa and then hits a wall miles off shore and then moves N to NNW next frame. 

[HillsdaleMIWeather]

Down to 985

[cptcatz]

71 knots in the NE quad. Special advisory coming with upgrade to hurricane?

[Normandy]

Windfield is greatly expanded with a second wind maxima already detected

[Scott747]

Looks like it has been upgraded in the database...

[Scott747]

About a 2-3 mb pressure drop on latest fix.

Official upgrade won't be till the next update in an hour or so.

[Superstorm93]

IR isn't spectacular with the heaviest convection once again located outside of the RMW 

[Superstorm93]

There's the eye...

 

[Modfan2]

5am cone from NHC 

[Prospero]

Not looking good for Tampa Bay. Our home is five blocks from Boca Ciega Bay at about 15ft elevation. We are not considered in a flood zone, but a 15 foot storm surge is not impossible.

Yea woke up to a hurricane watch and I’m sure evacuations will be next for some of us. 06Z ICON still has it coming into the greater Tampa area.
