Flood sirens sounded in upper Calderdale.
I do have a reason for being interested in this area BTW. T'other half was involved in a flood alleviation scheme in upper Calderdale back in the late 1990s. All sorts of wheezes had to be incorporated, for example gravel traps (to try and prevent culverts becoming blocked with rocks during high flow). The old mills in places like Todmorden were built on top of the river and the culverts just aren't big enough, and deepening them is very difficult without having to underpin a significant number of listed buildings. As a result, when the flow is too high, the river flows down the street or the railway (and through the railway station at Walsden).
Given it sounds like a semi regular occurrence which makes me wonder if the station has adaptations for rapid recovery from the flood waters flowing through it?
