A complex area of low pressure was situated over the British Isles with the centre towards South West England. The Otter Valley was under a slack air flow with variable direction. The day dawned clear but the sun's warming of the ground soon allowed for cumulus build up, and a gentle sea breeze from the south sprung up from late morning onwards. It was a dry day despite heavy, often dark cloudy skies during the afternoon. On this time-lapse footage the sun does bleach-out the video somewhat at first but when the cloud builds up then definition is restored.
