MWIS forecasts are published for the following day at 16.30, with an update when conditions deem it to be appropriate the following morning at 07.30.

Special arrangements apply during winter months when MWIS publishes forecasts at 13:30 each day.

On most days an amendment is made at around 07:30, but it should be noted that other amendments may well take place during the course of the day should changing conditions dictate.
