Historical Flood Alert Messages for this Area

  • We have only been collating detailed flood messages since May 2017.
  • Each Flood Alert may have multiple updates. The messages listed below may therefore be greater than the number of alerts detailed in the Flood Alert table above.

Flood Alert issued on 16 Feb 2020 18:55
Water levels in the River Hamble remain high, but are now falling slowly. In the last 24 hours, 34mm of rain has been recorded at Bishops Waltham, which is nearly half a month’s rainfall. We expect there to be significant out of bank flooding affecting land and roads at Frogmill, Durley and Botley. This will continue over the next 12 hours. Tomorrow (Monday 17/02/2020) only very small amounts of rain are forecast. Whilst this may cause a small increase in water level, it is not expected to flood property. We continue to monitor the forecast. If you have installed flood protection, we recommend that this is left in place until tomorrow morning. This Flood Alert will be removed by 12:00 on 17/02/2020.

Water levels in the River Hamble are high and continue to rise. In the last 18 hours 26mm of rain has been recorded in Bishops Waltham. Given the intensity of rainfall it is possible that Durley School may see flood impacts as Ford Lake rises faster than the River Hamble. Durley and Botley Mill may wish to operate their sluices to help reduce flood risk. The next high tide at Southampton is at 17:02 with a forecast tide level of 1.67 mAOD (4.41mCD). Further heavy rain is forecast with up to 15mm expected over the next 10 hours. Water levels are likely to remain high for the next 5 hours before they begin to fall. Flooding of property at Durley and Botley is not expected. A Flood Warning may be issued over the next few hours for Durley and Botley. No property flooding is expected at Bishops Waltham. We recommend installing flood protection at Durley School. This Flood Alert will be updated at 19:00 on Sunday 16/2/2020 or sooner if we think property flooding will occur.
