The first named storm of the season will hit Scotland on Friday, with three Met Office warnings coming into force. Storm Amy will bring heavy rain and gusts of up to 100mph within the worst-affected areas in the north-west of the country. Storm Amy follows another yellow warning which came into force at 5pm on Wednesday and will remain in place until midnight on Thursday. Up to 50-75mm of rainfall is expected in western parts of Scotland, while 100-150mm of rain could fall over the western-facing mountains. Amy will also bring more rainfall to areas already expecting heavy rain in the coming days, particularly in the west.
