Warning: The UK shipping forecast is produced for the Maritime & Coastguard Agency (MCA). Although this service is permitted to be delivered to commercial users for use on their web sites and intranet sites, you should be aware that the MCA could change aspects of the service, including the format, delivery times and content. We will try to notify you as soon as possible of any changes, but it is the service delivery mechanism that you are paying for and not the actual content.

About the script

The shipping forecast, which is provided by the Met Office and broadcast four times daily on BBC Radio 4, is highly structured to maximise the use of the available time. The basic order of the forecast is:

- GALE WARNINGS IN FORCE (IF ANY)

- GENERAL SITUATION

- AREA FORECASTS:

- WIND DIRECTION/SPEED: SEA STATE: WEATHER: VISIBILITY: (SHIP ICING IF APPROPRIATE)

Most of the forecast is self-explanatory, but in the synoptic preamble, and in the weather reports which follow, some terms are used which may not be generally familiar.

Movement of pressure centres

In forecast preamble/general situation:

Slowly   up to 15 knots
Steadily   15-25 knots
Rather quickly       25-35 knots
Rapidly   35-45 knots
Very rapidly   over 45 knots

Pressure changes

In coastal station reports, three hours is a 'standard' time period used in synoptic meteorology in mid/high latitudes.

Steady   Change less than 0.1 mb in 3 hours
Rising/Falling Slowly   Change 0.1 to 1.5 mb in past 3 hours
Rising/Falling   Change 1.6 to 3.5 mb in past 3 hours
Rising/Falling Quickly   Change 3.6 to 6.0 mb in past 3 hours
Rising/Falling Very Rapidly       Change more than 6.0 mb in 3 hours

Veering/backing of wind

A veering wind is one which changes direction such that it moves with the clock, e.g. from east to south through south-east. A wind that changes against the normal clock motion is a backing wind.

Visibility

For the visibility categories the following apply:

FOG   < 1 km (<1100 yd)
POOR   1 to 3.9 km (1100 yd to 2 n mile)
MODERATE       4 to 9 km (2 to 5 n mile)
GOOD   >= 10 km (>5 n mile)

Rules:

A

Areas always appear in the following order: Viking, North Utsire, South Utsire, Forties, Cromarty, Forth, Tyne, Dogger, Fisher, German Bight, Humber, Thames, Dover, Wight, Portland, Plymouth, Biscay, Trafalgar*, FitzRoy, Sole, Lundy, Fastnet, Irish Sea, Shannon, Rockall, Malin, Hebrides, Bailey, Fair Isle, Faeroes, Southeast Iceland. (* only included on midnight issue).

B

In order to save on words as many areas as possible should be grouped together, without losing important information. Rule A must be followed when areas are grouped together. As a general rule, in order not to confuse the listener, when, say, four or more areas are grouped together, not more than two (adjacent) areas should be 'excepted' following 'but' or 'except', e.g. 'Humber, Thames, Dover, Wight, Portland, Plymouth.... moderate with fog patches becoming good except in Humber and Thames' or 'Forth, Tyne, Dogger, Fisher, German Bight. Northwest 5 or 6 but gale 8 in Fisher and German Bight at first'. Grouping should normally be by common wind forecasts; differing weather and visibility can be dealt with by exception.

C

The content by areas is inflexible, being wind, sea state, weather and visibility (and superstructure icing if appropriate).

D

Maximum (excluding header line) of 370 words.

F

All areas with current gale warnings must be listed by rule A unless 4 or less areas do not have current warnings in which case the summary should read ".... in all areas except......" following rule A.

G

Except in the case of 'hurricane force 12' the word force is always omitted.

I

Forecasts are issued in local time (GMT/UTC or BST as appropriate).

J

Maximum (excluding header line) of 350 words.

K

Trafalgar included if appropriate.

Z7

In gale warnings, the suffix 'erly' is always used, e.g. Southerly
