ATL: JOAQUIN - Post-Tropical - Discussion

[EquusStorm]

This has already been the most intense tropical cyclone in the Atlantic from nontropical origins that we know of, now it's the strongest by winds as well. So yeah, at least for the satellite era, this is by far the most intense upper level low-generated hurricane known to have developed in this basin. Wish it had actually hit Cat. 5 though, just for the sake of record.

Category Sustained Winds Types of Damage Due to Hurricane Winds
1 74-95 mph
64-82 kt
119-153 km/h Very dangerous winds will produce some damage: Well-constructed frame homes could have damage to roof, shingles, vinyl siding and gutters. Large branches of trees will snap and shallowly rooted trees may be toppled. Extensive damage to power lines and poles likely will result in power outages that could last a few to several days.
2 96-110 mph
83-95 kt
154-177 km/h Extremely dangerous winds will cause extensive damage: Well-constructed frame homes could sustain major roof and siding damage. Many shallowly rooted trees will be snapped or uprooted and block numerous roads. Near-total power loss is expected with outages that could last from several days to weeks.
3
(major) 111-129 mph
96-112 kt
178-208 km/h Devastating damage will occur: Well-built framed homes may incur major damage or removal of roof decking and gable ends. Many trees will be snapped or uprooted, blocking numerous roads. Electricity and water will be unavailable for several days to weeks after the storm passes.
4
(major) 130-156 mph
113-136 kt
209-251 km/h Catastrophic damage will occur: Well-built framed homes can sustain severe damage with loss of most of the roof structure and/or some exterior walls. Most trees will be snapped or uprooted and power poles downed. Fallen trees and power poles will isolate residential areas. Power outages will last weeks to possibly months. Most of the area will be uninhabitable for weeks or months.
5
(major) 157 mph or higher
137 kt or higher
252 km/h or higher Catastrophic damage will occur: A high percentage of framed homes will be destroyed, with total roof failure and wall collapse. Fallen trees and power poles will isolate residential areas. Power outages will last for weeks to possibly months. Most of the area will be uninhabitable for weeks or months.

157 is cat 5...the SSHS was changed a couple yrs ago

[WPBWeather]

The storm2k map is wrong, it always processes a 155mph storm as a Cat 5. Check the NHC site, Joaquin is and has been a 155mph Cat 4 storm, it has to reach 156mph to be considered a cat 5.

I think it made a 5 anyway...

[TimeZone]

Did it officially become a cat 5 for a brief period?

Has to reach 157 mph now with new scale.

I think Joaquin went category 4-5 just on untapped energy alone.

[ozonepete]

One would think it likely hit cat 5 if even just briefly this morning, but there's not much chance that even the final end-of-year assessment will change it.

Can we settle on a Cat4.95 ?

[Sanibel]

Still impressive no matter what.


The Bahamas took a hard endurance hit.

Joaquin may not be done yet. The central dense overcast has become more symmetric and the eye has re-warmed over the past hour.

[bahamaswx]

Surprised to see the eye has come back again.

[EquusStorm]

If it does get bumped up in the next update, it's going to be one of the furthest north category fives in the basin's history. Definitely the furthest north for October.

If only there were recon, do any of you know the next mission?

First pass through the center at 7:30pm EDT.

Wow! It actually is looking awesome right now. There still is a decent chance that RECON will find a cat 5 this evening, especially if those cloud tops keep cooling. The symmetry is really impressive again.

[tolakram]

Someone has to post it.

[Aric Dunn]

its on the right side of the guidance.. bermuda might be dealing with this..

[Sanibel]

Improved tighter eye in my opinion.
