Thankfully no one seems too keen on making the storm anything other than a low-end hurricane/tropical storm with the exception of HMON which has it at around 959 MB on hitting the US mainland. This would likely be a mid-range category 2.
It's one to watch though as storms forming in that area can bomb very quickly. There's plenty of hot water for it.
 
God fucking dammit. I swear if that thing comes this way (nola) I'm going to flip my shit.

All, this storm is sitting around 90% chance to become a storm soon and will have 3+ days over the gulf before it hits. Due to surface temps and low sheer, when this thing forms and if it does miss a Yucatan hit, "Nate" may bomb out like Harvey did intensity wise.

Over the next 48 hours, I would recommend watching the NHC tracks on this development.

Do not rely on intensity models until a core is formed; they are inaccurate at this stage. Plus with the La Nina effect going on, expect a much higher probability of it being stronger than weaker than forecast (see Harvey). La Nina is not factored very well into models...

Interesting. NHC has landfall east of all of those points. NHC is showing landfall near Tallahassee Florida

That is pretty much exactly where the current Euro model (today 0z) puts it as well:

de_model-de-310-1_modsjuip.png


Landfall would be on 2017-10-08 (sunday) at 1800 UTC / 2 PM EDT.

Though currently, the same model predicts that it gets pretty windy, but nothing more:

Those are wind gusts at around 100 km/h ≈ 60 mph

this motion is expected to continue today. On the forecast track,
the depression should be nearing the coast of Nicaragua early
Thursday, move across northeastern Nicaragua and eastern Honduras
late Thursday, and emerge into the northwestern Caribbean Sea on
Friday.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
The depression is expected to become a tropical storm later today
or tonight.

The estimated minimum central pressure is 1005 mb (29.68 inches).


HAZARDS AFFECTING LAND

Very interesting video explaining why such a huge discrepancy between the GFS and Euro models. How tomorrow we will probably get much more clarity as to were this might be headed for landfall and what areas need to keep watch..

Current (12z) Euro model ensemble storm tracks:

de_cyclone-de-310-1_ersslm.png


Note that the wind speeds are probably wrong, at least the NHC has it a bit higher. Orange is where hurricane force begins, the light blue most of the tracks are in corresponds to 38-53 mph.

Closer look at where Nate makes landfall according to the main run:

de_model-de-310-1_modlpjjb.png


Landfall is on 8 October (Sunday) at 0900 UTC or 5 AM EDT.
 
Well new Orleans has declared a state of emergency. That escalated fast. I worked extra shifts all week to bolster the paycheck and now we may be closed all weekend. Ugh
 
Recon has already measured steep pressure drops starting and satellite is starting to show a strong circular convection. It is most likely that Nate will be a hurricane in the coming hours and is already exceeding by a wide margin the models in intensity. Chance for Rapid intensification is still very high.

So for Nate up here in ATL what should I be expecting? Looks like some bad winds mainly?

...TROPICAL WEATHER CONDITIONS POSSIBLE LATE SATURDAY NIGHT INTO
SUNDAY ACROSS NORTH AND CENTRAL GEORGIA...

Tropical Storm Nate, currently just east of the Yucatan
penninsula of Mexico, is expected to track north-northwest across
the Gulf of Mexico through Saturday, making landfall somewhere
along the central Gulf Coast Saturday night.

The latest track from the National Hurricane Center has Nate
turning northeast across Alabama, approaching northwest Georgia by
Sunday afternoon. Based on this current forecast track, the
probability of seeing tropical storm-force wind gusts, greater
than 40 MPH, is increasing across portions of central and north
Georgia throughout Sunday. Several hours of winds of this
magnitude would be capable of bringing down trees and powerlines.
In addition to the wind, periods of heavy rain could produce 2 to
6 inches of rainfall which may result in localized flash flooding,
especially across urban and poor drainage areas. A few tornadoes
are also possible within any of the more organized rain bands that
are associated with Nate.


As forecast confidence increases overnight tonight into Saturday,
Tropical Storm Watches may be issued for portions of central and
north Georgia.

This is an evolving and challenging forecast. Please stay tuned
to the latest forecasts and information from the National
Hurricane Center, and the National Weather Service in Peachtree
City.

Or, maybe really bad wind and rain. Bleh.

At least Nate is moving very quickly compared to the others.

I have no doubt they have been working very hard, but happy to see even more trucks making the rounds on Irma cleanup duty just in case. There was an abundance of debris still laying around, but the prudent thing is to get as much of it out of the way as possible just in case.

Not too worried about the wind, but we put up metal shields on the windows anyway. Way more worried about the flooding. If the current track and rainfall hold steady, our first floor will flood. Going to move everything that I can upstairs tomorrow.

Current model says it'll make landfall over Ocean Springs, MS. Not looking forward too it.
 
Just upgraded to a hurricane.

An Air Force Reserve Hurricane Hunter aircraft just penetrated the

winds are estimated to be 75 mph (120 km/h) with higher gusts.

So my wife and I are on the Cruise Ship Liberty of the Seas right now in the Gulf on the last few days of a 7 day cruise. We were suppose to stop in Cozumel but Nate caused our captain to skip the stop, push the boat to full throttle and get 110 notical miles of space between us and it. Right now we safe and I’m not worried about it causing us too many issue, the captain has cut back the throttle and given us an extra day at sea in place of the missed stopped, basically going to coast into Galveston for a Sunday morning docking.
