5.1 Background

Environment Canada’s Meteorological Service of Canada (MSC) is the agency responsible for delivering Canada's weather service. 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. 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 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.

5.2 Marine Warning Program

Warnings of extreme weather events that pose a threat to life and property at sea such as strong winds, freezing spray, high coastal waters, squall lines and other localized phenomena shall be issued for the offshore economic zone including the St. Lawrence Seaway and major inland waters.

Major inland waters are defined as having significant marine activity and where time to reach safe harbour is comparable to the marine weather warning lead time. The criteria for issuing weather warnings is based on national guidelines, but determined regionally to account for regional climatology and the nature of the regional marine community. The following table describes the warning program:

Table 5-1 - Synoptic Warnings

Synoptic warnings and warning criteria
Synoptic warnings*Warning criteria
Strong wind warning (1) Winds (2) 20 to 33 knots inclusive occurring or expected to occur in any portion of a marine area including any portion defined by a local effect or an "except" statement.
Gale warning Winds (2) 34 to 47 knots inclusive occurring or expected to occur in any portion of a marine area including any portion defined by a local effect or an "except" statement.
Storm warning Winds (2) 48 to 63 knots inclusive occurring or expected to occur in any portion of a marine area including any portion defined by a local effect or an "except" statement.
Hurricane force wind warning Winds (2) 64 knots or above occurring or expected to occur in any portion of a marine area including any portion defined by a local effect or an "except" statement.
Freezing spray warning Ice accretion rate of 0.7 cm/hr or more occurring or expected to occur in any portion of a marine area including any portion defined by a local effect or an "except" statement.

Notes:

*These warnings are included in the body of the text forecast.

  1. The strong wind warning program is active on a regional basis as required for coastal and inland waters during the recreational boating season. A warning is not required when the wind is described using the range 15-20 knots. This range is normally used for greater accuracy. 
  2. Gusts are excluded from the definition.

Range: With the exception of Note (1) above, when a range is used to describe the wind speed, the upper value of the range determines the warning category.

Table 5-2 - Localized Warnings

Localized warnings and warning criteria
Localized warnings/watches*Warning criteria
Squall watch Advance notice of conditions that are favourable to the development of squalls.
Squall warning Wind gust ≥ 34 knots associated with a line or an organized area of thunderstorms.
Tornado watch Advance notice of conditions that are favourable to the development of tornados.
Tornado warning Evidence of tornado formation (radar, report from a reliable source, etc.) over a marine area, or an existing tornado moving from land to an adjacent marine area.
Waterspout watch**  Advance notice of conditions that are favourable to the development of cold-air waterspouts.
High water level warning Issued to warn mariners and coastal populations of potentially hazardous impacts due to abnormally high water levels or waves along coastal areas.
Special marine warning/watch Used to describe conditions other than those defined above that may have potentially hazardous impacts on navigation.

Notes

* These warnings/watches are delivered using separate messages.

** Waterspout warnings are not issued.

Ice Warnings: refer to the Canadian Ice Services, Section 5.15.

5.3 Marine and Ice Forecast Program

Marine forecasts are issued for the offshore economic zone including the St. Lawrence Seaway and major inland waters.

For sea ice, ice forecasts are issued for offshore marine areas as well as the Great Lakes. The production schedule is detailed in each regional section of this chapter. The forecast program includes the following bulletins:

Table 5-3 - Marine Forecast Program

Marine Forecast Program
Forecast or bulletin nameDetails
Technical marine synopsis Provides the positions and trends of the main weather systems for the forecast period covering Days 1 and 2.
Marine forecast (or Regular marine forecast) Provides information on: synoptic warnings, wind, visibility, precipitation and freezing spray. It may include air temperature as appropriate. Valid for Days 1 and 2.
Recreational boating marine forecast Tailored to the needs of recreational boaters, it is available on a seasonal basis and only in specific regions.
Marine weather statement Issued when deemed necessary, it provides additional information on potentially high impact marine conditions.
Wave height forecast Provides information on significant wave heights for Days 1 and 2 (not available for northern and Arctic lakes or inland waterways).
Extended marine forecast Meant for longer-range planning purposes, it provides an extended marine wind outlook for Days 3, 4, and 5.
Iceberg bulletin Provides information on distribution of icebergs valid for the time of issue of the bulletin.
Ice forecasts Provides information on hazardous ice conditions for Days 1 and 2.
NAVTEX1 International Maritime Organization (IMO)-compliant NAVigational TelEX bulletin issued with each regular marine forecast or ice forecasts in a standardized abbreviated format - see section 5.8.1 for Abbreviations.
MAFOR1 This is a specialized coded marine forecast produced for Québec and Ontario regions.

Note

Note (1): More details on NAVTEX and MAFOR are provided at Section 5.8 and Section 5.9

5.3.1 Monitoring the Forecast

Forecasts are monitored, and amended as necessary, to reflect unexpected or changing weather conditions according to criteria based on the following principles:

  1. when safety or security is at risk;
  2. when inconvenience to the marine community will be extensive; or
  3. when the product could adversely affect the credibility of the marine forecast program.

5.3.2 Marine and Ice Forecast Areas

Marine forecasts and ice forecasts are issued for marine and ice areas as outlined in the regional maps. The sizes and boundaries of these areas are determined regionally based on the following considerations:

  1. marine traffic density;
  2. the ability to forecast to the proposed resolution;
  3. the degree to which, climatologically, marine weather varies; and
  4. the ability to distribute the information effectively to the marine community.

5.3.3 Current Conditions

Current weather data is available to Canadians for their local area. The frequency and quality of the data will be consistent with the standards established by the World Meteorological Organization (WMO). The date may include, as appropriate:

  1. wind speed and direction;
  2. atmospheric pressure;
  3. sky conditions;
  4. precipitation type;
  5. restrictions to visibility;
  6. wave height; and
  7. current temperature.

General information on current sea-ice will be provided to the marine community once a week to provide an adequate planning tool for those considering entering ice-encumbered waters.

5.3.4 Emergency Response

Meteorological support is provided during emergencies and includes the provision of meteorological information and forecasts. In the case of a pollution event, Environment Canada adheres to the “polluter pay” policy for the provision of all services. Where agreements are in place, Environment Canada will make its distribution systems available to transmit vital information during emergency situations.

5.3.5 Delivery of Marine Warning and Forecast Services

Delivery of marine warning and forecast services to mariners navigating waters within Environment Canada’s forecast areas of responsibility is primarily by mass communication in order to reach the greatest number of mariners through the standard communications technologies available to mariners. The following principles apply, regardless of the specific available technologies:

  1. Marine forecasts and warnings comprising the meteorological Maritime Safety Information (met MSI) issued by Environment Canada will be made available to the marine community via the Canadian Coast Guard Marine Communications and Traffic Services according to established procedures within the framework of the Global Maritime Distress and Safety System (see RAMN Part 4 Section 4.2.1 General Procedures – Systems – GMDSS).
  2. Internet access via the World-Wide Web. All forecast and warning information will be found at Weather.gc.ca. Mariners should note, however, that the internet is not part of the Maritime Safety Information system and should never be relied upon as the only means to obtain the latest marine forecasts and warning information. Access to the internet may be interrupted or updated information delayed without prior notice.
  3. Marine and Environmental Advisories, Watches and Warnings are distributed through various mechanisms including partnerships with national and regional media distributors and local emergency measures organizations.
  4. In addition to the aforementioned mediums, basic services to mariners and Canadians in general shall also be delivered by mass distribution in partnership with media, relying on current and developing technologies in radio, television, newspaper and the Internet. These distribution mechanisms represent the primary methods by which most Canadians receive their weather information, now and in the future.

5.4 Voluntary Observing Ship (VOS) Program

The VOS program has been discontinued within Canada. Environment Canada currently supports the Automated Voluntary Observing Ship program (AVOS) program and will support visiting VOS ships from other jurisdictions on a “best efforts” basis. Contact your regional PMO for further information.

5.5 Buoys Program

In order to complement the observational network, Environment Canada operates a network of buoys across the country. This data becomes part of the collection of weather reports sent to the distribution network and is used to improve marine forecasting. The location, WMO identifiers and names of the Environment Canada buoys are given in the regional annexes.

Mariners are requested to use caution when approaching buoys as mooring chains are normally not detectable from a ship and can be damaged or even severed if there is contact. Such a mishap could possibly result in the buoy going adrift thus requiring a costly effort to recover the platform. Please keep the regional PMO informed of any incidents involving buoys.

Buoy locations: Buoy positions are described in each specific regional annex.

5.6 MAREP (Marine REPorting Program)

MAREP gives mariners the opportunity to informally report local weather conditions and to receive up-to-date weather forecasts and warnings. MAREP stations are generally operated on a semi-volunteer basis by a member of the marine community who is concerned about marine safety. The stations operators are in regular contact with the Marine Weather Forecaster of the area.

Since the program is informal, the individuals at the stations do not provide a 24-hour service, but are likely available during day-time and early evening hours.

5.7 Port Meteorological Officers (PMOs)

In addition to a variety of other duties, PMOs also act as a liaison between Environment Canada and ships involved in the VOS and AVOS programs. This is to encourage vessels to report weather and ice conditions, to instruct observers about procedures and the use of code; to supply observing forms, handbooks (free of charge); to calibrate equipment; and, in some cases, to install, on loan, meteorological or oceanographic instrumentation. The PMO is also responsible for recruiting new vessels to participate in the AVOS program.

If a PMO visits your ship, feel free to ask questions about observing and coding, and reporting weather and ice conditions. Inform the PMO of any concerns you may have with forecasts, warnings, or facsimile products, especially if you have specific problems. The PMO will contact the appropriate party for investigation. Keep the PMO informed of your contact information.

5.8 NAVTEX

MSC will provide Canadian Coast Guard with marine forecast information in NAVTEX format for coastal and offshore areas of responsibility based on IMO standards. Marine forecast information provided will include:

  1. warnings (winds and ice accretion);
  2. synopsis (major features); and
  3. forecasts (wind, visibility, ice accretion, wave height).

Each bulletin will contain a WMO telecommunication header, a valid period, notes on parameters used within the bulletin, a synopsis section, a weather forecast section and a wave forecast section. Below is a sample of a partial NAVTEX produced for Canadian Coast Guard MCTS Sydney. Note that NAVTEX will make use of abbreviations: this is necessary in order to comply with the physical limitations of the NAVTEX system. In the example, text in superscript indicates how abbreviations are used.

5.10 Northern Canada

Includes: Western and Eastern Arctic, Hudson Bay & Major Inland Lakes of Manitoba, Northern Saskatchewan and Northwest Territories.

5.10.1 Marine Weather Forecast Program

The Prairie and Arctic Storm Prediction Centre (PASPC), which is jointly located in Edmonton and Winnipeg provides marine weather forecasts in support of Arctic marine activity during the open water season from summer into parts of the fall. Wave height forecasts are provided for salt water areas. The PASPC-Edmonton forecast area encompasses Lake Athabasca, Great Slave Lake, the Mackenzie River, as well as the waterways of the Western and High Arctic, and Baffin Bay.

The PASPC-Winnipeg provides marine forecasts for Hudson Bay, Hudson Strait, Foxe Basin, Ungava Bay, and Davis Strait. Marine forecasts are also provided for Lake Winnipeg (north and south basins), Lake Manitoba and Lake Winnipegosis during the open water season in support of pleasure and commercial activities.

The forecast program for the Manitoba Lakes continues through the winter months as a public rather than a marine forecast in aid of commercial ice fishing. Minimum and maximum temperatures along with wind chill are included in the forecast.

Note the following particulars:
 Warning TypesComments
1 Strong wind warning Applies to Manitoba Lakes, Lake Athabasca, Great Slave Lake and Mackenzie River

5.10.2 Weather and Ice Messages

Ship weather and ice reports in the international meteorological code, taken at the standard synoptic hours of 00:00, 06:00, 12:00 and 18:00 UTC are solicited from ships of all nationalities which have been recruited by their national weather service, or other weather services. These reports should be transmitted directly to the circuit using Inmarsat. Alternatively, the observation should be passed to the nearest Canadian Coast Guard MCTS Centre, irrespective of the ship's position. Reports made close to, or even within sight of land, are as important as reports made offshore, due to the greater variability of weather conditions in proximity to a coastline. Such reports contribute to the overall knowledge of Arctic weather from both a real-time operational perspective and from a climate perspective.

The PASPC welcomes weather, sea, and ice observations from the lakes. Real-time observations, and those up to a few hours after the event, are most valuable. Relay observations to 1 800 66STORM (1-800-667-8676).

5.10.7 METAREAs Forecast Transmission

During the navigation season, met MSI for sections of METAREA XVII and XVIII south of 75°N, and northwestern sections of METAREA IV, is broadcast via Inmarsat-C SafetyNET over Inmarsat’s Pacific Ocean Region (POR) or Atlantic Ocean Region-West (AOR-W) satellite network. Scheduled broadcast times are:

  • METAREA XVII (POR) at 03:00 UTC and 15:00 UTC daily.
  • METAREA XVIII (AOR-W) at 03:00 UTC and 15:00 UTC daily.
  • Northwestern METAREA IV (AOR-W) at 03:00 UTC and 15:00 UTC daily.

Met MSI for METAREAs XVII and XVIII will be transmitted using rectangular addressed messaging that encompasses waters comprising these two METAREAs until Inmarsat-C receivers or Mini-C terminals operating in Arctic waters have been updated to recognize the SafetyNET address code C3 = 17 and 18 for METAREAs XVII and XVIII respectively. Users should note that meteorological MSI received by their sat-C terminals may be labeled as navigational MSI.

Met MSI for the northwestern sections of METAREA IV is transmitted using rectangular addressed messaging that encompasses waters comprising Hudson Bay & Approaches. The SafetyNET address code for this rectangular area is C3 = 50n098w18030. Thus only those Inmarsat-C receivers aboard vessels navigating within the boundaries defined by this rectangular area will print out met MSI for the northwestern sections of METAREA IV.

During the navigation season met MSI for sections of METAREA XVII and XVIII north of 70°N is broadcast via High Frequency Narrow Band Direct Printing (HF NBDP) on 8416.5 kHz from the Canadian Coast Guard Marine Communications and Traffic Services (MCTS) Centre in Iqaluit NU. Scheduled broadcast times are 03:30 UTC and 15:30 UTC daily. Mariners should note that actual HF service provision dates will be announced by Canadian Coast Guard Notice to Shipping.

Mariners navigating northern or Arctic waters may also obtain METAREAs forecast bulletin via internet by accessing Environment Canada’s “Datamart” web page. However, users are cautioned that the internet is not part of the GMDSS MSI dissemination system and should never be relied upon as the only means to obtain the latest marine forecast and warning information. Access to the internet may be interrupted from time to time, or updates may be delayed. Mariners are advised to refer to the appropriate GMDSS-approved marine communication systems such as Inmarsat-C SafetyNET, HF NBDP, or international NAVTEX for the latest information. When accessing Environment Canada’s Datamart web page please ensure the page you are viewing is updated and not from your web browser’s cache. If in doubt, use your web browser’s Refresh or Reload button to update the web page.

It becomes operational when a storm system of tropical origin enters or threatens to enter the designated response zone (north of 36ºN and west of 41ºW) within 3 days. The CHC may begin to issue bulletins on a semi-regular basis up to 5 days prior to the expected tropical weather event so as to maintain consistent and informative messaging on the storm, and also as a tool for early contingency planning for the relevant emergency response agencies.

During the CHC’s operational phase bulletins are issued at regular 6-hour intervals. These bulletins include information statements for Public and Media notification, and technical messages for use by MSC and Canadian Forces weather offices. Bulletins are issued at 3-hour intervals when the storm’s impacts are occurring within MSC’s forecast areas of responsibility, including offshore waters.

5.15 Canadian Ice Service (CIS)

5.15.1 Ice Forecasts

Ice forecasts are produced where there is marine activity. The intent is to advise users of ice conditions including warnings that are in effect or that could develop during the day, the evening and the following day, in marine areas. Forecasts also provide a point by point description of the ice edge.

The iceberg bulletin is produced once a day. The purpose is to convey routine, general information on the iceberg distribution off the Canadian East Coast. The bulletin provides the estimated limit of all known icebergs and a general description of the number of icebergs for each marine area.
