Crossover names: do they keep same Pacific name?

[LarryWx]

The Atlantic will continue to use its original list of names, REGARDLESS of what happens with Adrian. It DOESN'T matter if the A storm Adrian re-develops in the Atlantic Basin because one thing doesn't have anything to do with the other. It will be the first time in history that the Atlantic will be using 2 "A" names since the policy was changed a few years ago.

Think about it this way, the Atlantic will borrow the name Adrian for a while, but in reality is NOT an Atlantic storm...it is a Pacific storm because of its origin...

OK, thanks Hyperstorm for clearing this up for us.

You're welcome. I can understand some of the confusion since there is hardly any information on the internet regarding this. I found out because of a paper I read a long time ago that mentioned something about it, but the information available is very limited...

From a document of the WMO (see link):
"The following rules apply for tropical cyclones passing from basin to another: the name will be retained if a tropical cyclone passes from one basin into another basin as a tropical cyclone, i.e. advisories are continuous. An unnamed tropical depression will also retain its number (e.g. Tropical Depression Six-E remains Tropical Depression Six-E) if it crosses into another basin.
Within a basin, if the remnant of a tropical cyclone redevelops into a tropical cyclone, it is assigned its original number or name. If the remnants of a former tropical cyclone regenerate in a new basin, the regenerated tropical cyclone will be given a new designation."

As stated in paragraph 3.3.1 of http://www.wmo.ch/web/www/TCP/OperationPlans/TCP30-English2004.pdf

HenkL, thanks very much for this info.

Someone should tell Fox News they keep saying it will change names

[Scott_inVA]

It would work just like any storm that moves over land, weakens to a depression and then moves back over water would.

The circulation MUST remain intact though for it to keep the same name from basin-to-basin.

I think Iris? in 1995 got the rules changed(it crossed from the Atlantic to EPAC)... how I do not know.

This came up last year with Ivan, remember? TPC (errantly, IMO) deemed the storm's circ was maintained from landfall through interior SE/Mid-Atlantic, then out to drift at sea before regaining named status.

The naming guidelines are accurately stated above, but TPC gets to decide what "intact circulation" is. Given their mind numbing logic with Ivan '04, this is like a floating strike zone in baseball.

They and CNN are woefully underprepared for the upcoming season. I saw a CNN weather dummy call Adrian a hurricane sometime around 4:00 AM today: "We've got a HURRICANE, Perfectly Coiffed News Lady! *points frantically at satellite map*"

He later backed off and called it a tropical storm a couple of hours later.

Thanks Hyperstorm. That could get really confusing when going to count stats at the end of the year, too. Sorry for having a blonde moment.

Further proof of why we do NOT NEED INDUSTRY SOLELY DISSEMINATING
INFORMATION ON WEATHER.

No, the rules are different for storms that cross basins. These must remain a tropical cyclone to retain its name. Within a basin, the circulation can completely dissipate. If the remnants re-develop, the old name is reassigned.

I believe we are saying the same thing regarding TCs that cross basins.

My contention (and that of some forecasters at TPC and at least one person I know at HRD) is that "Ivan the Second" did not consistently maintain true TC circulation. As a result the remnant piece of Ivan's energy that spun back down around was not the same core and should have received its own name.
