River Ems
Less rain fell in the Westbourne area on Tuesday night, than was predicted. The River Ems rose slightly, but not as much as we thought it might. River levels are now slowing in their rise and with the last of today's rain expected to clear by 10:00 15/1/2020, should not rise further on Wednesday. However, further heavy rain is possible Thursday afternoon 16/1/2020, which should not cause significant flooding, but may generate another small increase in water levels. We shall keep this message in place until we have greater confidence in Thursday's impacts. Looking further ahead, there is the chance of showers Friday, but more settled weather possible from the weekend, maybe into next week. Please remain prepared with flood protection products in Emsworth and Westbourne, if you have them, in case flood risk increases Thursday. We have been operating our structure at Constant Springs to help reduce flood risk. This message will be updated by 13:00 16/1/2020.

River Ems
The River Ems is high following a wetter than average autumn and winter. River levels have risen by a few centimetres so far today. An additional 20mm of rain is possible before mid morning Wednesday 15/1/2020. If all of this rain occurs, minor flooding is possible from 02:30 15/1/2020 in North Street, River Street and the Wren Centre Westbourne. Water is likely to affect fields, rural roads and gardens, but could get close to a few riverside properties. We believe there is still some capacity through Constant Springs and Emsworth Brook Meadows so that impacts will be less here. The river will stabilise by Wednesday afternoon, but further rain is possible Thursday (16/1/2020) and Friday which could cause river levels to rise again. Please install flood protection products now in Emsworth and Westbourne, if you have them as a precaution. We have been operating our structure at Constant Springs to help reduce flood risk.
