ATL: NATE - Post Tropical - Discussion

[wxman57]

Still no reports of sustained tropical storm-force winds between Gulfport and Mobile, at least from the stations below (I included New Orleans). I did see some gusts to 34kts or more at most of the stations. I see TWC mets are trying to explain why they aren't observing any significant winds along the coast. Perhaps those winds aloft aren't making it down to the surface.

Gulfport cam from an hour ago and now. Not too dramatic and it looks like this location will escape the worst as the center looks to make landfall right on top of or just east of Gulfport.

Nate became extratropical earlier today..still a potent storm, but, it's really not surprising. We are in October. It happens. Still giving a great storm surge, but, the center of the system has been classic extratropical for the last 8 hours. For a minute I thought it was an eyewall replacement, but, it never really had an eye. I'm glad it was a flop for New Orleans. We had nothing and it was very smart for the mayor to lift the curfew at 8:30. It had to be done, but, he did the right thing for people who have plans and the 40,000 visitors that remained here this weekend. Let's have fun. It's over for NOLA. Godspeed Biloxi/Ocean Springs. You'll be fine. This is nothing.

There is nothing extratropical about this.

Storm surge rising and wind increasing in Biloxi, Mississippi !! #HurricaneNate #StormSurge
11:29 PM - Oct 7, 2017 · Mississippi, USA

[Sean in New Orleans]

No Cat 1 has an eyewall spread out like that...it's a floppy circle that is almost 50 miles wide. It's very tropical, but, it hit those cooler waters just South of Louisiana and it was like "no way, don't like that." It has been in the very beginning stages of becoming extratropical, but, does it matter? It's still strong. It changed it's appearance on radar and on satellite 8 hours ago. No biggie. Like I said, it's October. It still had 85 to 90 mph winds. Time for Fall. It's right around the corner. Arapahoe Basin in Colorado will be skiing in the next 5 days. It's just the time of the year. We had a crazy tropical season. Hope it's less active next year....

[Chris_in_Tampa]

Hurricane season officially ends November 30th.

[wxman57]

Lots of buoys around Nate, and the strongest wind I've seen today has been 45 kts. I've never really trusted those SFMR winds, as they don't really measure air movement itself. I'm watching TWC try to explain where the hurricane-force winds and 11 foot surge are. Perhaps the surface winds aren't really as high as SFMR was estimating, or those winds are no longer at the surface, they're elevated. The storm surge is lower because the winds are lower. Note that it only takes a few feet above normal tides to wash over Highway 90 and flood parts of the coast there.

TWC reporter just said with excitement that there was a 56 mph gust at Keesler AFB. Finally, some wind, he exclaimed!

[Bamagirl2408]

Still no reports of sustained tropical storm-force winds between Gulfport and Mobile, at least from the stations below (I included New Orleans). I did see some gusts to 34kts or more at most of the stations. I see TWC mets are trying to explain why they aren't observing any significant winds along the coast. Perhaps those winds aloft aren't making it down to the surface.

Local met on Fox 10 News Mobile is getting worst weather I have seen. Rain and wind. No weather channel met there. Difference in him and Seidel in Biloxi is quite interesting. You are correct. A few squalls but no significant sustained winds at all.

The 10 second estimated surface winds by SFMR instrument are less now than they were about an hour and a half ago. They are about 75mph now.

[tolakram]

Eyewall appears to be on top of this location now, surge really came up quickly.

I don't think that there are any 75 mph winds in Nate. Maybe 50-60 mph, and 60 may be a stretch. If Nate's winds were that high then Biloxi would have reported more than a 32 mph sustained wind by now, and that's the highest I've seen on the MS coast.
