Those hoping to enjoy street parties and celebrate King Charles III Coronation outdoors this weekend in Pembrokeshire are being put on notice.

The Met Office is predicting rain across Wales on Saturday and Monday with heavy, thundery downpours predicted on Sunday.

Met Office Deputy Chief Forecaster, Steven Keates, said: “On Saturday we will see showers developing from late morning in some central, eastern and northern areas, but also with some sunny spells through the day.

"At this stage, it looks like London could avoid the showers in the morning before some develop through the afternoon.

"Heavier rain is expected to move into the southwest of the UK and heavy showers are likely for parts of Northern Ireland.

"Winds will remain light away from the far north where gusty winds will begin to ease.

"Highs of 20°C are possible in London in any sunshine, with mid to high teens possible elsewhere.”

As celebrations continue through the Bank Holiday weekend, the Met Office said Sunday could see heavy, possibly thundery downpours across Wales.

The Met Office added that Monday was more uncertain but the weather looked to remain "unsettled".
