Particles of dust from major wildfires in Canadian are affecting the air quality in Wales on Friday. Sharing a picture of the sunrise over Haverfordwest BBC weather forecaster Matt Taylor said the "reddish hue" was an indicator of the air quality.
On Friday morning he said: "There is a slightly reddish hue in the sky this morning which is an indication that air quality is not particularly great across the UK right now. It will improve slowly over the weekend. There is also a tiny bit of wildfire dust all the way from North America that is in the sky in western parts this morning." The Met Office says that a red sky appears when dust and small particles are trapped in the atmosphere by high pressure.
