EPAC: BONNIE - Post-Tropical - Discussion

Finds a hurricane lol
This is a joke^

[NDG]

Looks to have a true closed circulation per recon to finally be classified, about time

Lol no hurricane, but enough evidence to upgrade to TS Bonnie imo. Still rather broad and could use some tightening up:

Finally!

Wow about time this got named!
Talk about the nick of time, this storm was trolling us for over a week now!

Maybe I've missed it, but as Bonnie seems to keep it's name when moving into the Pacific, will the strength there also count for the Atlantic season. So if it for example becomes a hurricane after passing over Central America and emerging in the Pacific, will Bonnie also become a hurricane for the Atlantic season? I guess the same holds for ACE?

15 advisory cycles at a PTC…let’s see if anything else this year tries to surpass that record.

Well, I thought Alex already was exeptional...

Good question, I doubt that would be the case, once Bonnie crosses over, assuming it survives central America, the ACE should begin counting for the EPAC. It would be funny if Bonnie became a major in the Epac and robs the atlantic some ACE. I would also think the hurricane tally goes to the EPAC, or both basins if somehow Bonnie achieves hurricane intensity today

So there aren't any guidelines for that? Seems like the logical option, but I was wondering if there's really some standard procedure for that.

There are guidelines. They were enacted for Otto in 2016. Bonnie will effectively become an EPAC storm, and will count towards the EPAC's seasonal ACE counts. Atlantic Bonnie will only be counted as a TS in our basin.

I hope not!

It will retain the name but the WMO will still recognize it as an EPAC system after it crosses over (meaning all tracking guidance will be EPAC thereafter). The WMO recognizes 10 regions/agencies for tracking tropical systems:

The Caribbean, Gulf of Mexico, and North Atlantic (NHC/RSMC Miami) - https://www.nhc.noaa.gov/
Eastern North Pacific (NHC/CPHC/RSMC Honolulu) - https://www.nhc.noaa.gov/
Central North Pacific (CPHC/RSMC Honolulu) - https://www.nhc.noaa.gov/aboutcphc.php
Western North Pacific and South China Sea (JMA/RSMC Tokyo) - https://www.jma.go.jp/jma/indexe.html
Southern Pacific (FMS/Nadi) - https://www.met.gov.fj/
Southern Pacific below 25S (MetService/TCWC Wellington) - https://www.metservice.com/warnings/tro ... e-activity
Southwest Indian Ocean (MFR/RSMC La Reunion) - http://meteofrance.com/
Northern Indian Ocean, Arabian Sea, and Bay of Bengal (IMD/RSMC New Delhi) - http://mausam.imd.gov.in/

Within Australia/New Zealand there are 2 agencies that have different areas of responsibilities
Australian Tropical Cyclone Warning Centre's (TCWC) - http://www.bom.gov.au/cyclone/tropical- ... /warnings/
Port Moresby Tropical Cyclone Warning Centre - http://www.pngmet.gov.pg/warnings/smartalert/

Hermine in 2010 was the first example of this - https://en.wikipedia.org/wiki/Tropical_ ... mine_(2010). Here is visually how WMO tracked that crossover:

[MarioProtVI]

Finally Bonnie has arrived. About damn time, now time for a rare feat, a crossover!

An intact crossover, no less! That would be the first ATL-EPAC intact crossover since 2016 if I'm correct.

Dear Colin, Danielle, Earl, and the rest,

If you are planning on becoming a PTC, please do not give us wx trackers a big headache like your predecessors Alex and Bonnie did and remain a PTC for multiple days in a row. Thank you.

Sincerely,
Category5Kaiju

Finally. Earlier advisory had landfall in 24 hours but with Bonnie still not really slowing down, landfall will probably be within 12 hours. The Atlantic might be the only region on the planet where storms in the deep tropics move at an unreasonably fast pace.

[Category5Kaiju]

Welp, there you go.
