Flood Alert issued on 7 Jun 2024 12:21
Groundwater
Groundwater levels are high, but falling slowly, at our two boreholes in Piddington and Ray Farm in the High Wycombe area. Groundwater levels are above normal for this time of year and communities may continue to be affected by groundwater flooding as the catchment remains sensitive to further rainfall due to high groundwater levels. The weather forecast is for a dry day today (07/06/2024) and into the weekend. Next week from Monday 10/06/2024 is expected to be predominantly dry, but showers may develop through Monday and Tuesday. Rainfall totals are not expected to be significant. Low-lying land, gardens, roads, and cellars will continue to be at risk of flooding. Due to the nature of groundwater flooding, this situation could continue for several weeks or longer. Avoid driving or walking through floodwater as there may be concealed hazards. We are continuing to monitor groundwater levels and will update this message by Friday, 14/06/2024, or as the situation changes.

Groundwater
Groundwater levels are high, but falling slowly, at our two boreholes in Piddington and Ray Farm in the High Wycombe area. Groundwater levels are above normal for this time of year and communities may continue to be affected by groundwater flooding as the catchment remains sensitive to further rainfall due to saturated ground and high groundwater levels. The weather forecast is for isolated showers today, some of which could be heavy. Saturday and Sunday are forecast to be dry with further unsettled weather expected next week. Low-lying land, gardens, roads, and cellars will therefore continue to be at risk of flooding. Due to the nature of groundwater flooding, this situation could continue for several weeks or longer. Avoid driving or walking through floodwater as there may be concealed hazards. We are continuing to monitor groundwater levels and will update this message by Friday, 07/06/2024, or as the situation changes.

Groundwater
Groundwater levels are currently rising at our Piddington Ray Farm borehole near the High Wycombe area as a result of recent rainfall. Groundwater levels are above normal for this time of year and have now reached a level where communities may be affected by groundwater flooding in the coming days. Groundwater levels remain sensitive to further rainfall due to saturated ground and high groundwater levels. Therefore groundwater levels will continue to slowly rise over the coming days in response to recent rainfall. Low-lying land, gardens, roads, and cellars may therefore be at risk of flooding. Due to the nature of groundwater flooding, this situation could continue for several weeks or longer. We are continuing to monitor groundwater levels and will update this message by 05/04/2024, or as the situation changes.

Groundwater
Groundwater levels are currently rising at our Piddington Ray Farm borehole near the High Wycombe area as a result of recent rainfall. Groundwater levels are above normal for this time of year and have now reached a level where communities may be affected by groundwater flooding. We expect levels to rise over the next few weeks and be responsive to further sustained rainfall. Low-lying land, gardens, roads, and cellars may therefore be at risk of flooding. Due to the nature of groundwater flooding, this situation could continue for several weeks or longer. We are continuing to monitor groundwater levels and will update this message by 29/03/2024, or as the situation changes.


Flood Alert issued on 29 Apr 2020 09:22
Groundwater
Groundwater levels are high at our Piddington observation borehole near High Wycombe. Groundwater has reached a level where communities - particularly those near Radnage and in the Hughenden Valley - could be affected within weeks by flooding from groundwater. However, due to the recent drier conditions, groundwater levels have continued to drop over the last week. Levels at the Piddington observation borehole are below the level where we would expect to see flooding impacts but there may be locations where groundwater is flooding at the surface. Low-lying land and roads would be at risk of flooding first. Due to the nature of groundwater behaviour, this situation could continue for several weeks or longer dependent on rainfall conditions. The weather forecast is for an unsettled week (29 April to 5 May 2020) with potentially heavy showers at times. We continue to monitor groundwater levels and will update this message next week by 6 May 2020, or as the situation changes.


Flood Alert issued on 22 Apr 2020 08:56
Groundwater
Groundwater levels have slightly declined but remain high at our observation site, Piddington borehole, in the Wycombe area including Radnage and the lower Hughenden Valley. Groundwater levels in this area are at a level where communities may be affected in the next few weeks by flooding from groundwater. Low-lying land and roads are at risk of flooding first. Due to the nature of groundwater behaviour, this situation could continue for several weeks or longer, and the speed at which flooding will occur is dependent on rainfall conditions. The weather forecast is for a mainly dry week (21 April to 28 April 2020). We continue to monitor groundwater levels and will update this message next week by 29 April 2020, or as the situation changes.

Low-lying land and roads would be at risk of flooding first. Due to the nature of groundwater behaviour, this situation could continue for several weeks or longer dependent on rainfall conditions. The weather forecast is for a mainly dry week (15 April to 21 April 2020) with potential for showers on Friday and Saturday.

Groundwater
Groundwater levels have stabilised at a high level at our observation borehole in Piddington. Communities in Radnage and the Hughendon Valley area are in the groundwater alert area which may be affected by groundwater flooding. Groundwater levels are above normal for this time of year. Levels have stabilised but remain high and will remain high for the next few days and weeks. Low-lying land and roads will therefore be at risk of flooding. Due to the nature of groundwater behaviour, this situation could continue for several weeks or longer and the speed at which flooding will occur will be dependent on rainfall conditions. The weather forecast is for a mainly dry week (8 April to 15 April 2020) with potential for isolated heavy rain today and Sunday.
