On 3 September 2017 a complex of frontal systems brought prolonged and, occasionally, heavy rain to the southwest of England, causing flooding in parts of Cornwall.

Floods in Cornwall
Date & Time
02 September 2017 21:00 UTC–03 September 18:00 UTC
Airmass RGB, Rainfall radar

The Met Office analysis on 3 September 2017 at 00:00 UTC showed several fronts approaching the west of the UK. The broad swathe of frontal cloud associated with these fronts can be seen on the Meteosat-10 Airmass RGB image (Figure 1, top right, click to expand).

The cloud and associated rain moved very slowly eastwards, as can be seen on the Airmass cloud animation, 2 Sept 21:00 UTC–3 Sept 18:00 (MP4, 7 MB). Also on the animation cumulonimbus (CB) tops can be seen embedded in the frontal cloud.

Outbreaks of heavy rain can be seen, as areas of bright pink, on the 05:00 UTC radar image (Figure 2) and the radar animation. These areas tie in well with the convective cloud tops visible on the Airmass RGB image at the same time (Figure 3).

The outbreaks of heavy rain and the fact that the rain lasted all day, led to the flooding in parts of Cornwall
