Southwesterly winds of 30-40 knots associates with a low pressure to the northwest of Scotland are expected to sweep the Channel. Conditions are expected to go light on Monday followed by the onset of another major depression on the Tuesday (although this is set to track to the north of the UK and is forecast to bring less severe winds to the channel).
