The Met Office issued this warning this afternoon.
Warning period: 8 pm 31 October until 8 am Tuesday 1 November
An area of rain will move northwards overnight, turning heavy for a time before clearing away northeast on Tuesday morning.
While many places are unlikely to see impacts, it is possible that the rain band could become slow moving for a time giving localised accumulations of 20-30 mm in 2 to 3 hours and perhaps 40-50 mm in 3 to 4 hours which could lead to some surface water impacts and delays to transport.
