Alert Details
The Environment Agency has issued a flood alert for the River Itchen at Mansbridge and Riverside Park (Alert ID: 065WAF124). The alert was raised on February 21, 2026, following observations of high river levels and anticipated tidal impacts.
Affected Areas
The alert covers the Solent and South Downs area, specifically impacting Mansbridge and Riverside Park in Hampshire and Southampton. Specific locations identified as at risk include the White Swan Pub, its access roads and parking areas, a local car garage, and parts of Riverside Park.
What You Should Do
Residents and business owners in the warning area are advised to consider activating flood protection products, including defenses around the White Swan pub. The Environment Agency is currently monitoring river levels and rainfall while liaising with Southampton City Council regarding the operation of Woodmill. Residents should continue to monitor local conditions.
Expected Conditions
Flooding is possible on February 22, 2026, driven by a combination of high tides and elevated river flow. The incoming tide is expected to restrict the River Itchen's flow to the sea, creating a flood risk for approximately 1.5 hours on either side of each high water period. While the river's flow has been slowly decreasing, up to 18mm of heavy rain is possible tomorrow, which would cause levels to rise again.
Timeline
The primary flood risk is forecast for Sunday, February 22. From Monday, February 23, through Wednesday, February 25, conditions are expected to improve as only minimal rainfall (up to 1mm daily) is forecast. This message is scheduled to be updated by 14:00 on February 23, 2026.
