#CloudHour Competition for World Meteorological Day

To celebrate World Meteorological Day (#WorldMetDay) on 23rd March, the Royal Meteorological Society (RMetS) are running a competition with @StormHour. The theme of this year's World Meteorological Day is 'Understanding Clouds', so we are running a mini cloud competition.

Submit your cloud photographs via Twitter using the hashtag #CloudHour before midday 23rd March 2017 for a chance to win a Weather Photographer of the Year calendar. Winners will be announced at 1:30 on the 23rd March.

RMetS are also running our main annual photographic competition, Weather Photographer of the Year 2017, in conjunction with The Royal Photographic Society. It is open for entries until 7th June 2017. Entries can be made by visiting the competition website.
