Post-Tropical Cyclone Wanda Discussion Number 31 NWS National Hurricane Center Miami FL AL212021 300 PM GMT Sun Nov 07 2021
Wanda is no longer generating deep convection in association with its low-level circulation. In fact, most of the colder cloud tops seen on satellite over the center right now are actually upper-level cirrus associated with a cold frontal boundary part of a larger mid-latitude cyclone southeast of Greenland. In addition, an 1156 UTC ASCAT-B pass over Wanda's circulation shows that the north side is beginning to open up into a trough as the cold front is encroaching on the system. These above factors suggest that Wanda is no longer a tropical cyclone, and the system is now classified as a post-tropical low as of this advisory. The winds remain 35-kt based on the peak wind retrieval of 33-kt from the scatterometer data on the southeast side of the circulation.
The system has been accelerating to the northeast with the latest estimated motion at 045/22 kt. The post-tropical cyclone should continue to accelerate to the northeast until it merges with the baroclinic zone approaching it. A 12 hour point is provided for continuity and to indicate the transition to an extratropical cyclone, though its quite possible the system will be fully absorbed by the frontal boundary by then. The track guidance at 12 hours is tightly clustered, and the NHC track forecast at that time fame follows the consensus aids closely.
This is the last NHC advisory on Wanda. Additional information on this system can be found in High Seas Forecasts issued by Meteo France under WMO header FQNT50 LFPW and available on the web at www.meteofrance.com/previsions-meteo-marine/bulletin/grandlarge/ metarea2.

I updated your YouTube embed. I had coded it to allow the start time, automatically recognizing it in a link, but I only coded it to recognize the YouTube.be format where there was no "s" at the end of the "t" parameter. I now recognize both:
https://youtu.be/yG07WSu7Q9w?t=64 https://www.youtube.com/watch?v=yG07WSu7Q9w&t=64s
When you visit a YouTube.be link it has no "s", and then when it goes to YouTube.com it adds it. But in the forum I convert all YouTube.be links to the standard YouTube link. Should work no matter if you have the s or not now in either link type. I thought about adding the fact that I allowed the start time in the link, but wasn't sure how to really tell people that without cluttering up that area where you add the embed. So far I just have the Twitter option to hide the conversation. (the tweet that a tweet might be replying to)
I haven't mentioned it yet, but I also have an image upload feature that I haven't tested too well yet. There will also be some configuration options with how the Imgur uploaded image will be displayed, like in the Imgur container (as it is now) or just as an image at a size you can choose, but I haven't finished coding that part of it yet. (or completed the Imgur upload history section so that people can delete items in their Imgur upload history) I'm working on converting old archive lists to the new mobile format at the moment. Those pages and the search engine pages are kind of the last public areas I need to complete for the new mobile format. The administrative section has a lot more things I need to update though to the mobile format. |
