Saharan dust returns

Saharan dust is expected to reach us today and could produce vivid sunset and sunrise colours in places.

Just a few days after the recent bout of Saharan dust travelling to our shores, strong winds over North Africa have once again stirred up large amounts, which is expected to reach us today.

The desert dust consists mainly of tiny mineral dust and can rise up to a height of 5 to 10 km into the atmosphere.

Across parts of central and southern England, there may be spots of "blood rain". "Blood rain" is when the Saharan dust is precipitated out of the air and falls to the ground with the raindrops.

Dust deposits may be noticeable on your cars, so don't bother with a car wash today! Check the WeatherRadar to see exactly where it may rain.

As a result of the dust in our air, intense and vivid colours are possible during sunset on Tuesday evening and sunrise Wednesday morning.

This is especially likely to be the case across southern and eastern England, so don't forget to send in your shots for us to feature!
