The weather warning, for heavy rainfall, will be in place from 9am on Saturday until 6am on Sunday, with strong winds also set to accompany the rain. The Met Office said of the warning: "Rainfall will spread northeastwards on Saturday, and become persistent and at times heavy. "From mid-Saturday onwards, increasingly strong gusty winds and perhaps some thunder will also accompany the rainfall, further increasing the risk of disruption. "By the early hours of Sunday, persistent heavy rain will have likely cleared from Wales, with this rain easing for Northern England and Scotland by dawn on Sunday morning. "Showers then follow and winds remain strong through Sunday."
