I’m gonna bet NHC goes 155 or maybe 160 anyway this advisory. She’s gonna go a little lower and respond wind wise in the next few hrs I’d expect. 

Same here man! Dead on!

Eta thinking of the wild expectations y'all put out

 

(Not a criticism of y'all who know much more than me, I also thought it'd be sub 910 and still won't throw in the towel on Cat 5)

She's not gonna get much lower and faster when the core looks like this lol. I'm not sure whether or not this peaked a few hours ago though.

Wouldn't shock me but I think it's still strengthening but maybe slower than earlier

Raw T up to 8.4 per UW CIMSS. This may look perfect but it takes time to deepen.  If there's a large drop between passes I think we make a run at 900mb overnight. If there is not a large drop then I think this will max out at 915-920mb

It might be, waiting on the next pass for sure. Though I think the truly rapid intensification is probably over with a well defined concentric band taking shape.

Don't ask me why but the HWRF is actually showing the strongest winds in the southwest quad

For the convo about best looking storms we forgot a relevant one in this region: Mitch at peak 

This will have similar effects too: tons of rainfall causing catastrophic flooding.

Just gonna post up the discussion:

Hurricane Eta Discussion Number  10
NWS National Hurricane Center Miami FL       AL292020
1000 PM EST Mon Nov 02 2020

An Air Force Reserve reconnaissance aircraft has found that Eta has 
explosively deepened into a strong category 4 hurricane with maximum 
sustained winds of 130 kt and a minimum central pressure of 927 mb. 
Eta has maintained a small 10-nmi-wide eye that is evident in 
satellite imagery and on the San Andreas, Colombia, weather radar. 
The radar data also suggest that concentric eyewalls may be forming, 
which would be an indication of the onset of an eyewall replacement 
cycle (ERC) and a capping of Eta's intensity and also an end to the 
rapid intensification cycle of the past 36 hours. The initial 
intensity of 130 kt kt is based on 700-mb flight-level winds of 137 
kt and SFMR surface winds of 130 kt. Some additional strengthening 
is expected, and Eta could become a category 5 hurricane before 
landfall occurs. After landfall, Eta should quickly weaken while it 
moves over the mountainous terrain of Central America.

Eta has slowed and is now moving southwestward or 245/06 kt. There 
is no significant change to previous track forecast reasoning. A 
mid-level ridge over the south-central United States should steer 
Eta west-southwestward toward the coast of Nicaragua with the 
hurricane making landfall early Tuesday.  After landfall, Eta should 
turn westward and then west-northwestward, and move across Central 
America through Thursday. Eta's low-level circulation may not 
survive its passage over the mountainous terrain of Central America, 
but most of the global models continue to depict a cyclone or its 
remnants moving over the northwestern Caribbean Sea by late-week and 
into the weekend. Therefore, the new NHC track forecast continues to 
show the system emerging over the northwestern Caribbean late in the 
period, although this portion of the track forecast remains 
uncertain.

Since Eta is likely to be a very slow-moving system after it makes
landfall in Central America, torrential rains and flooding will be
a major threat.

Key Messages:

1. Catastrophic wind damage is expected where Eta's eyewall moves
onshore along the northeastern coast of Nicaragua tonight or early
Tuesday.  Tropical storm force winds are beginning to reach the
coast within the Hurricane Warning area in Nicaragua, and residents
there should have completed their preparations.  A Tropical Storm
Warning is also in effect for the northeastern coast of Honduras.

2. A catastrophic and life-threatening storm surge, along with
destructive waves, are expected along portions of the northeastern
coast of Nicaragua near and to the north of where the center makes
landfall.  Water levels could reach as high as 14 to 21 feet above
normal tide levels in some parts of the hurricane warning area.
Preparations to protect life and property should now be complete.

3. Through Friday evening, heavy rainfall from Eta will likely
lead to catastrophic, life-threatening flash flooding and river
flooding across portions of Central America, along with landslides
in areas of higher terrain.  Flash and river flooding is also
possible across Jamaica, southeast Mexico, El Salvador, southern
Haiti, and the Cayman Islands.

I still won. 931 mb 150 mph, NHC verified. ;-)

Lol. Bro, I haven't looked at the original forecasts yet at all--I'm not saying I expect a cat 5 because of MY forecast, I'm saying it because THE NHC said it would. I don't care whether I win, good work, excellent job. But I haven't looked through yet to verify everything. Busy looking at the data.
