December Hydrological Outlook published

Summary

The one-month outlook is for December flows to be above normal across most of northern and western Britain, with an increased likelihood of exceptional flows in some regions. These projections reflect the exceptionally wet November in much of northern Britain. In actuality, early December has already witnessed exceptional rainfall and flooding in northern England and parts of Scotland, so it is highly likely that total flows for December will be exceptional. With meteorological projections favouring wetter-than-average conditions over the next three months, there is an increased likelihood of above normal winter flows in many northern and western areas, and high groundwater levels are also likely in aquifers in these areas. In the south and east of England, winter river flows and groundwater levels are largely expected to be normal or above, although below normal levels are likely to persist in some eastern areas.
