The following tables describe the various types of marine warnings, watches and advisories comprising the Marine Weather Alerting Program: The criteria for issuing marine weather alerts is based on national guidelines, but determined regionally to account for regional climatology and the nature of the regional marine community. Major inland waters are defined as having significant marine activity and where time to reach safe harbour is comparable to the marine weather alert lead time. Advisories are issued as a caution to mariners for weather-related events that may not meet warning criteria but may nonetheless pose significant inconvenience or hazard to navigation. Localized warnings and watches are also issued for phenomena such as squalls, high water levels and waterspouts. These alerts include warnings of extreme weather events that can pose a threat to life and property at sea, such as gales or storms and freezing spray. The MSC is responsible for issuing marine weather alerts for coastal and offshore waters, as well as the St. Lawrence Seaway, and major inland waters such as the Great Lakes. The constant stream of data coming from both automated and manned coastal observation stations, as well as ships and weather buoys, is supplemented by satellite imagery, weather radar and a full set of numerical weather products adapted for marine operations. The Canadian Coast Guard also plays an important role in disseminating forecasts and warnings, and in collecting and relaying weather information from volunteer observers and ships. The MSC offers a broad range of products and services that are designed to help mariners make informed decisions on how weather will affect them. Environment and Climate Change Canada’s (ECCC) Meteorological Service of Canada (MSC) is the agency responsible for delivering Canada’s weather service.
