FLOODS, lightning and problems travelling on the roads could be on the way weather watchers are warning.
The MET office has issued a Yellow Warning for heavy rain across Wales, and parts of England and Scotland, for Sunday.
The warning is in force from 0.15am, Sunday until 8pm, Sunday.
It says: "Although some places will stay dry, heavy rain may cause some localised flooding and travel disruption.
"There is likely to be flooding of a few homes and businesses, bus and train services will probably be affected with journey times taking longer.
"Spray and flooding on roads will probably make journey times longer and some interruption to power supplies may occur due to lightning."
The weather is in stark contrast to Saturday's sunshine and warm temperatures in the 20s.
