Storm Henry brought traffic chaos to Clydebank and led to some terrifying times for this Duntocher family but there was a nicer side to the storm - some beautiful skies with rare nacreous clouds.

The colourful cloud formations are known as polar stratospheric clouds or nacreous formations due to the mother of pearl effect and are most commonly found in polar regions.

The form at around 70,000ft - much higher than others clouds - and the irridescent colours are produced by ice crystals refracting the suns rays which gives a rainbow effect.

Thanks to all the readers who sent in their pictures.
