Re: When a name is retired is it permanent?

I understand it like this with my own explanations of different situations...
---------------
Storms going from one basin to another...
If a storm travels from the Atlantic to East Pacific and it is a tropical storm or tropical depression the entire way across Central America with advisories issued at least every 6 hours, it retains the Atlantic name.
If a storm travels from the Atlantic to East Pacific and the circulation can be followed the entire way across Central America and advisories stopped at some point before it crossed over completely then it would get an East Pacific name if it redeveloped.

Storm redeveloping in the same basin...
This is a little confusing. Ivan (it could be tracked when it made a big loop around the US) and the origin of Katrina (a disturbance combined with the remnants of tropical depression 10 and was called tropical depression 12 when it developed) come to mind. (see the last paragraph of the first discussion of tropical depression 12, which later strengthened into Katrina) That "remnant of a tropical cyclone" I am not really sure about though.
If a storm becomes a remnant low and the circulation can still be tracked and it redevelops, then it retains the same name.
If a storm becomes a remnant low and merges with some other convection not associated with the remnant low and then develops, then it would get a different name if you could not tell which it formed from, the remnant low or the convection that merged in.
The really confusing one is if a storm loses its circulation. If it opens up completely into a wave and does not merge with anything else and then redevelops I think it would keep the same name as long as you could track it well enough, but I'm not really sure. |
