“Storms will likely already be underway for Northern Ireland and parts of Scotland by early Monday, before also developing in parts of England and Wales by late morning and across the afternoon. Storms are expected to begin to subside from the west later.
“Very locally, 20 to 30 mm of rain are possible in one hour, and up to around 50 mm in three to six hours. Frequent hail and lightning are also possible.
