What is the difference between navigational warnings and danger messages?

SOLAS regulation V/4 requires Contracting Governments to publish navigational warnings, i. e. messages promulgating information relating to dangers.Β 

The UK does this through NAVTEX messages and Notices to Mariners published by UKHO. SOLAS regulation V/31 requires the master of every ship which meets with specified dangers to transmit a danger message to ships in the vicinity and to the competent authorities.
