Gusts of 50mph to 55mph are likely within the yellow warning area, and up to 60mph is possible in the most exposed coasts and areas of higher ground.
Flooding to homes and businesses is likely, while some interruption to power supplies and other services is possible, the spokesman adds.
Bus and train services are likely to also be affected.
The Met Office spokesman added: “After further rain on Monday, which could extend into Tuesday in some eastern and southeastern areas, it should become somewhat drier and brighter more widely around midweek.
“However, there are signals for the potential of further wet and windy weather towards the end of next week.”
