Sat 4 Oct Wales

This period could begin with some very disturbed weather for the British Isles, with a deep low probably passing to the north or northwest of the country. This means there is potential for very strong winds and some further heavy rain, especially, but exclusively for more northern areas. Into the following week, a broadly westerly type looks most likely, with further weather systems running in from the Atlantic. On balance, southern areas stand a better chance of seeing longer drier interludes. However, confidence in the details remains on the low side, owing to ongoing Atlantic tropical cyclone activity. Overall, temperatures probably fairly close to average by day and whilst some overnight frost cannot be ruled out, especially later in the period, nothing overly cold is signalled at this stage.
