My collection of UN Agencies' flags are based both on William G. Crampton's "Flags
& Coats of Arms" and the official logos of each agency.
The blue color is taken from a UN logo at its website:
"http://www.un.org".

The World Meteorological Organization modified its logo on 26 June 2012 during the 64th Session of the Executive
Council. Compass became yellow, and abbreviations are omitted from the logo.

All signals are found in Ch. 5 of ‘WMO Publication No. 9, Weather Reporting, Volume D, Information for Shipping’. Most are specific to individual countries, but two are shown in Annex II ‘National Systems of Visual Storm Warning Signals (Day Signals) as offered by WMO on line (sometimes): http://www.wmo.int/pages/prog/www/ois/Operational_Information/VolumeD/VolumeD.pdf

The first signal is really a set of two flags, a yellow one with thin red
ascending diagonal stripes (is the number important? I count seven) above a
white one bearing a thin red saltire. The second signal is a red pennant with
two vertical blue stripes. I could not find these in the country list and
suppose they were abolished in the past but not removed from the table.

These seem to be ICS letter flags spelling "yv" (Yankee
and Victor). Pairs of ICS flags have usually
separate meanings; any idea about this?
