As in strong 1 concern?
I'm concerned it's already a strong 1.
Plane is getting in there now though, should have the answer in 30 minutes or so.

Looks to really be gaining strength. The eye is forming very rapidly.
With the increase strength will it shift more to the west ?

The track is pretty locked in, passing near or over the New Orleans metro. Strength doesn't matter at this point, the steering is strong and is already in control.

10-4. Thx for all the insight
Posted on 10/28/20 at 3:28 am to lsufan112001
00z Euro showing gusts 80-90 mph for the city and over 100 out in Plaquemines and Da Parish. The GFS wasn't too far off this but a little east and puts the big gusts farther east too but the same sort of numbers in the east side of the system.
This might catch some people by surprise.

Man i'm not liking this at all.

Yep. New Orleans metro is going to wake up in a few hours with the possibility of a 2 coming right on through tonight.

Getting a little breeze in BR already.

Recon shows the strengthening assumed but nothing too out of the box. Pressure probably down to 984 at least. Winds maybe could be justified to be called 80 mph max. Eye has started to cool off again too.
So strengthening, but not as much as I feared about 30 minutes ago.

So people who work a night shift in Baton Rouge should be okay to drive around 10pm or so?

NHC aggressive with winds, going 85 mph and 982 mb at 4 am.
Looks like they're going to raise the forecast to 100 mph at max strength. Waiting for discussion to confirm.

So a Cat 2 landfall. Well, I think this might get people's attention in the morning.

Hurricane Zeta Discussion Number 15
NWS National Hurricane Center Miami FL AL282020
400 AM CDT Wed Oct 28 2020
The satellite presentation of Zeta has improved significantly
overnight with deep convection wrapping around an eye that at times
as been fairly well defined. An Air Force Reserve Hurricane Hunter
aircraft that has just began its reconnaissance mission into Zeta
has reported a pressure that has fallen to 982 mb and a 25-30
n-mi-wide eye during it first pass through the center. It is
somewhat surprising that the plane did not report stronger winds
during its northeast eyewall pass given the improved satellite
presentation, and using a blend of the aircraft data and recent
objective and subjective satellite estimates yields and initial
intensity of 75 kt. It is possible the winds have yet to catch up
to the improved satellite appearance, but since Zeta will moving
over warm waters and in a light wind shear environment this morning
some additional strengthening is likely. Although cooler waters
and increasing southwesterly upper-level winds over the northern
Gulf of Mexico are likely to cause the cyclone's intensity to
level-off or even come down slightly, Zeta is expected to reach the
northern Gulf coast as significant hurricane by late this afternoon.
The NHC intensity forecast is at the upper-end of the guidance, a
little above the latest HWRF prediction. After landfall, Zeta will
weaken while it moves over the southeastern United States, but the
cyclone is forecast to become an extratropical gale-force low
pressure area off the Mid-Atlantic coast Thursday night. The
post-tropical cyclone should be absorbed by frontal boundary over
the western Atlantic on Friday.
Zeta has turned north-northwestward and has begun to accelerate as
anticipated. A vigorous upper-level low moving into west Texas
will cause Zeta to accelerate north-northeastward today, which will
bring the center of the hurricane over southeastern Louisiana by
late this afternoon. The cyclone is expected to continue to
accelerate ahead of the trough over the southeastern United States
tonight and Thursday. The dynamical model are in very good
agreement and the latest NHC track is a blend of the various global
models. The new track forecast is very close the previous official
forecast.
Given Zeta's acceleration near landfall, strong winds are likely
to spread well inland along the northern Gulf coast this evening
and tonight.
KEY MESSAGES:
1. A life-threatening storm surge is expected along portions of the
northern Gulf Coast by late today, with the highest inundation
occurring somewhere between the Mouth of the Pearl River and Dauphin
Island, Alabama. Residents in the Storm Surge Warning area should
follow any advice given by local officials.
2. Hurricane conditions are expected this afternoon within portions
of the Hurricane Warning area between Morgan City, Louisiana, and
the Mississippi/Alabama border. Damaging winds, especially in gusts,
will spread well inland across portions of southeast Mississippi and
southern and central Alabama tonight due to Zeta's fast forward
speed.
3. Through Thursday, heavy rainfall is expected from portions of the
central U.S. Gulf Coast into the Tennessee Valley, Ohio Valley,
Southern to Central Appalachians, and Mid-Atlantic States near and
in advance of Zeta. This rainfall will lead to flash, urban, small
stream, and minor river flooding.

Yeah, I was a little surprised the winds weren't higher too and 85 is a little above what I think that pass would have supported but it's not unreasonable I guess. The high winds are closer to the center now and show the storm is tightening up. What was an anemic SW quad has really picked up with wind too.
VDM has a closed eyewall with an elliptical eye and a 983 mb pressure reported. The closed eyewall part is not what I wanted to see.
