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.

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
The groundwater level at Preston Candover and in Alresford is high, but it is falling in both locations. At Preston Candover, the current rate of fall is between 1 and 2 cm per day. In Alresford, the current rate of fall is 3 cm per day. Over the next few weeks, groundwater will continue to prevent septic tanks from operating effectively in Old Alresford. In Preston Candover, groundwater will still affect a small number of cellars. Over the next 5 days, the weather should remain fairly dry, and levels will continue to fall. Given the current rate of fall, it will be at least 6 to 8 weeks before groundwater stops causing impacts in the villages. 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 Wednesday 08/04/2020

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.
