The warnings include one - at Collingham - which states 'immediate action is required'. Here are the locations and information for each warning (information correct 7.30am Jan 20):
1. Lower River Calder catchment
River levels are forecast to continue to remain elevated across the Lower River Calder Catchment as a result of persistent rainfall. Further rainfall is expected throughout today (20/01/2021) which will elevate river levels further. Consequently, flooding of property, roads and farmland is possible. Areas most at risk are low lying land, roads and farmland. Our field teams have checked defences and cleared screens ahead of the rainfall and we are liaising closely with our partners to ensure they are ready to respond. Please put your flood plan into action and activate any property flood protection products you may have, such as flood barriers and air brick covers. Avoid using low lying footpaths near watercourses and plan driving routes to avoid roads which may be flooded. This message will be updated by 12:30pm, 20/01/2021, or as the situation changes.
