A Storm Brewing

We thoroughly enjoyed sausage and chips at the viewing area of Felixstowe Port this evening while hoping for a sunset. Instead we saw these black storm clouds rolling in which I thought were quite spectacular, I can always blip a sunset another day.
This is the view at the mouth of the estuary where the River's Stour and Orwell meet. The white tower is a radar tower for marine navigation at the entrance to the Ports of Felixstowe, Harwich and Ipswich.
