ATL: GONZALO - Post-Tropical - Discussion

[NDG]

108 mph sustained winds now at Commissioners Point, these winds are stronger than in the northern wall.

[NDG]

From BWS:

Lights are flickering...

WNW winds
Commissioner's point: 88 g 112 kt
St. David's 54 g 84 kt
Causeway 72 g 98 kt

.... BWS building taking a beating in these WNW winds... even with hurricane shutters we are feeling a breeze in the building. My office faces WNW, as does all operations of forecasters and observers. We are not as jovial as we were in the north side of Gonzalo

[NDG]

Confirmation that the southern eyewall is stronger than the northern eyewall with the airport's latest report, wow!!!!

gusts to 113mph!

[Hammy]

How likely is it that this was Cat 3 at landfall?

[cycloneye]

Damage has been reported by the Bermuda authorities.From 11 PM discussion.

The following information is provided at the request of the Bermuda
Weather Service -- damage to the old and new hospitals has been
reported, the AWOS weather sensors at the Bermuda International
Airport have been damaged due to saltwater inundation and are
inoperable, and the RCC Bermuda Radio Maritime Operations Center at
St. Georges has been damaged and is inoperable.

81 kt sustained (10-min) equates to about 90 kt (1-min), or solid Cat 2 winds. So MAYBE that back eyewall had Cat 3 winds somewhere.

Web cam is showing is if a freight train is going through the Island.

[Sanibel]

That's that back side band. Probably some forcing from the front.

[NDG]

St Davis just reported a wind gust of 133 mph.

The front is still nowhere near Gonzalo, that's just pure pressure gradient.

[gatorcane]

St Davis just reported a wind gust of 133 mph.

Once there is daylight tomorrow morning, we will probably see widespread damage with those kind of gusts...

think it is trough interaction. Fay also had strong winds west of the center, as did Igor 4 years ago

if this structure remains, Canada would get hurricane conditions early Sunday

[Sanibel]

As did Wilma in '05.

Yes but those winds are from an elevated reporting station, probably at the surface wind gusts are probably closer to the 120 mph, but still very strong nonetheless.

OK yes that would make sense regarding the trough.

[floridasun78]

i hope webcam still good in morning

[NDG]

Wow, 144 mph wind gusts now reporting at St Davis!!!!

[CrazyC83]

Now the debate will begin again over the landfall intensity. 95 kt seems most reasonable again with the stronger backside, but any stronger winds opens back up 100 kt.

I have the weather channel on at the moment and heard 112 mph, assuming this is sustained given the 108 mph mentioned on here earlier.
