The times I've listened to the coastguard giving lists of local nav warnings out and naming each one Whisky Zulu. But whats the relevance of Whisky Zulu to a nav warning

Whisky Zulu is the International code for Navigation Warning, particularly for NAVTEX.

I have a vague feeling that its derivation concerns minefield designations, WW2, and that it was carried over as a general navigation warning.
No, I'm not that old, but I've sailed with people that are.

Makes sense, Ken; WZ = Warning Zone ?
Aircraft to this day use 'QNE' etc as it was easy to transmit on wartime morse...

Small drift... QNE not used much anymore. However, QNH is used universally. Makes the aircraft touchdown at the airport elevation ... generally a good idea

An explanation of these aviation altitude acronyms (or maybe backronyms)...
QNH - Query Newlyn Height
Set your altimeter relative to the national sea level datum at Newlyn. Altimeter reads height above mean sea level.
QFE - Query Field Elevation
Set your altimeter relative to the highest point of the airfield you intend to land at. Altimeter reads height above the airfield to which it applies.
And other Qxx TLA's that are not used much more.

Q codes are seldom used except for altimetry.
However, the QRH (Quick Reaction Handbook = emergency/abnormal checklist) gets used more or less depending on the type of aircraft...

As mentioned above, WZ is the international Prefix for Radio Navigation Warning.
Minefields are designated - QZR ...

Err yes, that's where we came in. But why?
"Minefields are designated - QZR."
As I recall (and it was a long time ago from a old feller who drove Walruses for the Fleet Air Arm) different minefields had different identity letters and WZ was one that stuck.
But I'm very probably wrong.

Can you say where you got this, please?
According to The International Code of Signals 1969 Part III which I believe is still in use Nav Warnings are M signals e.g. MZ = "Navigation is dangerous in the area around...lat ...long"
WZ is one of the W weather series of signals and means "What are the forecast sea conditions in my area (or area around lat...long...)

All from the International Q codes as agreed by the ITU:Small drift... QNE not used much anymore. However, QNH is used universally. Makes the aircraft touchdown at the airport elevation ... generally a good idea

Interestingly that link suggests there are no Q codes for V, W, X, Y, or Z
