A low pressure system was centred to the north-west of the British Isles. The Otter Valley was in a slack maritime polar air stream to start the 3rd but slowly the isobars tightened and the wind increased through the day. There was a developing low pressure area to the south over Brittany but this did not affect here until the early hours of the 4th. There were showers around, but these mainly formed over the sea and quickly died out over land.

 A deep low pressure system was centred over northern England and the Otter Valley was in a brisk NW airflow. Despite a showery airstream, the showers mainly affected north and west coasts and it stayed dry. The low pressure was spawned from tropical air being pushed northwards ahead of Hurricane Nadine. With warm air aloft, rainfall amounts were very high across many parts of northern England.

With a small ridge of high pressure to the south west of the British Isles it made for a fine day in the Otter Valley, after a cloudy start. There were decaying weather fronts to the south and west but they stayed well away making sure that things remained dry for this weather station, though there were a few, sharp showers further inland.
