Richard Miles, of the Met Office, told the PA news agency: "Storm Celia over Spain is indeed pulling a dust cloud up from the Sahara, which could potentially reach as far as the south of the UK,"
"However, we don't expect significant impacts – the most likely would be on the cloudscapes at sunset, but as conditions are likely to be generally overcast and wet for much of the day this is unlikely to amount to much. There are no air quality warnings.
"People in the south might find a bit of dust left on their cars as the rain washes it out of the skies today."
Images captured by satellites have also shown dust over France.

Wednesday is expected to be cloudy for most of England, Wales, and eastern Scotland, with rain becoming heavier and more widespread in central and eastern areas later in the day.
Rain in England will then begin to clear as many regions turn cold, with patchy frost and some rural mist, the Met Office has said.
Showers, frost and fog will continue to hit parts of the UK for the rest of the week.
