There is a developing low pressure system, currently off Canada, which has been named by the Irish Met service as Storm Ashley, the first named storm of this season.
It is expected to develop fast on Saturday night.
Currently it is expected to impact the Island of Ireland (north and south) and Western Scotland, as well as parts of North West England.
If it develops as expected this could impact most if not all ferry services to Ireland and the vast majority of CalMac services on the West Coast of Scotland, as well as roads in those areas, and possibly rail services due to associated heavy rain. Power outages are also possible. There is another low pressure system in the Firth of Clyde today (Friday) which is heavily impacting various ferry services in the area.
Keep a close eye out on the news and weather forecasts for developments. As always with such storms impacts could be more or less, and it may also change track.
Not unusual for the time of the year.
