Thanks sky9, and all other contributors. Looks like sky9 has confirmed that volmet does indeed come from the French.
The literal translation of the french text he/she posted, according to an online translator, so excuse the grammar, is:
Apart from the weather transmissions of images, there are "vocal" transmissions of weather information dedicated to the aircraft. Called VOLMET (FLIGHT METéorologique) and ATIS (Final Automatic Information Service), this information are transmitted by the airports or aerodromes in VHF and by some stations in band HF."
So, VOL MET = FLIGHT MET
Thanks again
