Maritime Safety Information (MSI) radio broadcasts
MSI broadcasts are announced by Guernsey Coastguard to alert mariners of the latest wind, sea conditions, and navigational warnings in their respective sea areas. All Navigation Warnings and Safety Broadcasts could include, live firing warnings at Fort Le Marchant, information on maritime events (such as sailing regattas, swimming events) and wind warnings issued by Jersey Met. MSI Broadcasts will be announced by Guernsey Coastguard on VHF Channel 16 before being broadcast in full on VHF Channel 20.
The full Channel Islands Shipping Forecast will not be included as part of the MSI broadcast for the Bailiwick as this is undertaken by Jersey Coastguard for the whole Channel Islands sea area. The Channel Islands' Shipping Forecast will be available on request to mariners by contacting Guernsey Coastguard. Alternatively, the shipping forecast is available on Jersey Met's website https://www.gov.je/weather/Pages/Shipping.aspx or broadcast on BBC Guernsey's AM FM DAB and online services at certain points in the day.
The MSI will generally be broadcast at the following times (All times in UTC/GMT) 01:33, 05:33, 09:33, 13:33, 17:33, 21:33.
