The Met Office has said in the first half of this week will see more frequent rain in the northwest of the UK, with various fronts bringing periods of showers and some longer spells of rain for parts of Northern Ireland, western Scotland and parts of northwest England.
Those further south and east will see drier conditions through the start of this week, with patchy cloud and sunny spells and temperatures into the high teens or low 20s Celsius for many.
Met Office Deputy Chief Meteorologist Chris Bulmer said: “Rain will be particularly persistent in western Scotland from Wednesday onwards, with the heaviest rain over hills and mountains, though pulses of heavier rain will extend more widely at times, during Thursday in particular.
“From later Wednesday through to Friday morning, 50-75mm of rain is expected across a wide area, with in excess of 100mm possible over west-facing mountains. Wind is an accompanying hazard from late on Thursday, with this initially most likely in exposed western coasts.”
Chris added, “The situation becomes more complex later in the week as tropical cyclones Humberto and Imelda, currently over the southwest Atlantic, influence our weather, increasing the risk of a deep low developing near the UK.
“If this materialises, we could see some very strong winds as well as further heavy rainfall Friday into Saturday, but at this time the development and track of this system remains uncertain. We’re monitoring this closely.”
