Groundwater
In Preston Candover and Old Alresford, groundwater levels are high and rising slowly. In the last 3 months, prolonged, higher than average rainfall (353mm), has been recorded in Bishops Sutton. From Friday 20/12/2024, it is possible that rising groundwater will reduce the ability of septic tanks at Old Alresford to operate properly. In Preston Candover, a small number of properties may experience cellar flooding. Unsettled weather is expected to return to Hampshire from Wednesday 18/12/2024 into Thursday 19/12/2024 with between 15 and 35mm of rain possible. Following this rainfall, groundwater levels may begin to rise more rapidly. Friday 20/12/2024 and Saturday 21/12/2024 are expected to be mostly dry. We expect groundwater levels in Preston Candover and Old Alresford will likely continue rising for most of December in response to this week’s rain. We continue to monitor the groundwater levels and weather forecast. If you use pumps to help reduce water levels, please ensure that they can operate. This Flood Alert will be updated by 17:00 on Tuesday 24/12/2024.

Groundwater levels remain high, but following another week of fairly dry weather, they continue to fall, albeit slowly. In Preston Candover and Old Alresford, levels have lowered by 3cm in the last 7 days. The weather remains dry until Wednesday (10/03/21), further rain is then forecast. Between Wednesday and Friday (12/03/21), forecast rainfall totals are not overly large (10 to 20 mm) but it may cause a very slight increase (5 cms) in groundwater level. Over the next week, the current situation will not change significantly. At the lower end of Preston Candover village, the need to pump water from cellars will continue. In Old Alresford, a small number of cellars and septic tank operation could also remain affected. We continue to monitor the forecast. Pumps used to reduce water levels will still be required over the next few weeks. This message will be updated by 12:00 on Monday 15 March 2021.

Groundwater
Groundwater levels remain high and continue to rise very slowly. In the last 8 days, almost half a month’s rain (42mm) has been recorded at Bishop’s Sutton. In Preston Candover, the groundwater level has risen by 7cm. In Old Alresford, it has only risen by 2cm. Rain continues today (20/01/2021) with a further 15mm expected. From Thursday (21/01/21) to Sunday (24/01/21) only very small amounts of rain are then forecast. Over the next 5 days, there could be two outcomes. The rain may just be enough to cause the onset of cellar flooding in a very small number of cellars at the lower end of Preston Candover village. Or, it may keep the groundwater a few centimetres below a level where cellar flood impacts occur. Widespread groundwater flooding is not expected. We continue to monitor the forecast. If you use pumps to help reduce water levels, please ensure they can operate. This Flood Alert will be updated by 12:00 on Wednesday 27/01/2021.

Groundwater
At Preston Candover and Old Alresford, groundwater levels are high, but they are just stabilising following 3 months of above average rainfall (recorded at Bishop’s Sutton). At the lower end of Preston Candover village, groundwater is close to emerging in cellars. From Monday (11/01/2021) until Friday (15/01/2021) further rain is forecast. Forecast totals are not overly large, but if this rain does affect the catchment, then groundwater levels will continue to rise (albeit very slowly) over the next 7 to 10 days. From this time onwards, it may begin to prevent septic tanks from operating effectively in Old Alresford. It may also affect cellars in a very small number of properties at the lower end of Preston Candover village. Widespread groundwater flood impacts are not currently expected. We continue to monitor the forecast. If you use pumps to help reduce water levels, please ensure they can operate. This Flood Alert will be updated by 12:00 on Wednesday 20/01/2021.
Flood Alert issued on 15 Apr 2020 10:04
Groundwater
The groundwater level continues to fall. In the last 7 days, the level has reduced by more than 0.17 m in both Preston Candover and Alresford. The weather remains dry until Friday (17/04/2020), when rain and then heavy showers are forecast into the weekend. Next week, the weather is similar with further showers possible at times. It is unlikely that this rainfall will cause groundwater levels to rise. The overall situation will continue to improve, although given the current rate of fall, it will be at least 4 weeks before groundwater stops causing impacts in the villages. However, next week, if the weather outlook remains favourable, and we are confident levels will continue to fall, then we will look to remove this Alert. We continue to monitor the forecast. This Flood Alert will be updated or removed by 15:00 on Wednesday 22/04/2020.
Flood Alert issued on 8 Apr 2020 12:21
Groundwater
Groundwater levels continues to fall. In the last 5 days, the level has reduced by more than 0.1m in both Preston Candover and Alresford. Over the next 5 days, the weather is mostly dry, but it will be interspersed with periods of showery rain, especially through Easter weekend. Given the current forecast totals, the rainfall should not cause groundwater levels to rise. It will be at least another 4 to 6 weeks before groundwater stops causing impacts in the villages. We continue to monitor the forecast. This Flood Alert will be updated by 15:00 on Wednesday 15/04/2020.
Flood Alert issued on 30 Mar 2020 10:41
Groundwater

Groundwater
The groundwater level at Preston Candover and in Alresford is high, but is just stabilising from the heavy rainfall recorded over the last few weeks. Groundwater will be preventing septic tanks from operating effectively in Old Alresford. A small number of properties will be experiencing cellar flooding in Preston Candover. Over the next 5 to 10 days, the weather should be much drier, except for this weekend (14/03/2020 and 15/03/2020) when 10 to 15mm of rain is forecast. Rainfall this weekend will cause levels to rise a little, perhaps by 2 to 3 cm. Drier weather forecast next week, means that levels should stabilise, but in terms of height, will be very close to a threshold where a larger number of cellars can be affected in Preston Candover and Northington. We continue to monitor the forecast. Please ensure any pumps used to protect property can operate. This Flood Alert will be updated by 15:00 on Tuesday 24/03/2020.

Groundwater
The groundwater level at Preston Candover is high. It had stabilised in response to the heavy rainfall over the last few weeks, but is now rising in response to the rainfall recorded today. Groundwater will be preventing septic tanks from operating effectively in Old Alresford. A small number of properties will be experiencing cellar flooding in Preston Candover. Tomorrow and Saturday (07/03/2020) should remain fairly dry. From Sunday (08/03/2020) onwards, small amounts of rain are forecast. Over the next few days, impacts won’t change significantly. However, much now depends on rainfall over the next 2 to 3 weeks. It is still possible that a larger number of cellars in Preston Candover and Northington will be affected this spring. We continue to monitor the forecast. Please ensure any pumps used to protect property can operate. This Flood Alert will be updated by 15:00 on Thursday 12/03/2020.

Groundwater
The groundwater level at Preston Candover is high, but just stabilising from the heavy rainfall recorded in the last few weeks. Groundwater will be preventing septic tanks from operating effectively in Old Alresford. A small number of properties will be experiencing cellar flooding in Preston Candover. Tomorrow and into Saturday (29/02/2020), further rain is forecast. This will cause levels to rise a little, but it is unlikely that impacts will alter significantly. Next week, unsettled weather will continue to affect the South. Further heavy or continued rainfall over the next couple of weeks, would flood a larger number of cellars and roads in Preston Candover and at Northington. We continue to monitor the forecast. We would like communities to prepare for continued groundwater flood impacts over the next few weeks. This Flood Alert will be updated by 15:00 on Thursday 05/03/2020.

Groundwater
The groundwater level at Preston Candover is high and rising, although the rate of rise is just starting to slow. In the last 24 hours it has increased by 0.1m. This week, we expect groundwater to prevent septic tanks from operating effectively in Old Alresford. Some properties are experiencing cellar flooding in Preston Candover. Over the next 5 days, small amounts of rain are expected each day. Groundwater will rise for at least the next 8 days. Without further heavy rainfall in that time, it may just peak below the level where cellar flooding affects a larger number of properties in the Candovers and in Northington. We continue to monitor the forecast. We would like communities to prepare for groundwater flood impacts over the next few weeks. This Flood Alert will be updated by 12:00 on Thursday 27/02/2020.
