2.6.5 EMMA warning message

stations to skippers to inform them of special meteorological situations. EMMA does
not provide continuous weather information, but only warnings of wind, rain, snow and
ice, thunderstorm, fog, extreme temperatures (low and high), flood, fire in the forest.
These messages are additional to the Notices to Skippers warnings.

tents of the message, do the following:
