Further details


Further details

A period of heavy rain will affect first Southeastern England and then parts of East Anglia on Sunday evening, lasting through much of Monday. Although there is much uncertainty in these rainfall totals and how far West the heaviest rain will occur, accumulations of 25-40 mm are possible, and 50-70 mm in places during this period. The heavy rain will be accompanied by strong to gale force Northerly winds, and it will be cold enough to produce some snow on high ground such as the North and South Downs, although this is unlikely to settle.
