Alert Details
The Environment Agency has issued a Flood Alert (Severity Level 3) for the Solent and South Downs area. The alert was officially raised on the evening of February 15, 2026, in response to rising river levels and tidal conditions.
Affected Areas
The alert specifically covers the Mansbridge and Riverside Park areas in Southampton, Hampshire. Key locations at risk include the River Itchen, the access road and car park near the White Swan Pub at Mansbridge, and footpaths within Riverside Park.
What You Should Do
Residents and business owners in the affected areas are advised to consider activating any flood protection products they may have, including defenses around the White Swan Pub. The Environment Agency is currently monitoring rainfall and river levels and is liaising with Southampton City Council regarding the operation of Woodmill. Residents should continue to monitor local conditions and updates.
Expected Conditions
Flooding is possible due to a combination of heavy rainfall and a high tide at Southampton, which occurred around 10:30 PM on Sunday. These conditions are expected to prevent the River Itchen from draining to the sea for approximately two to three hours. While the bulk of Sunday's rain has passed, additional rainfall is forecast for Tuesday, February 17, which could increase the flood risk.
Timeline
The alert became effective at 9:30 PM on February 15, 2026. An update on the situation is expected to be provided by 4:00 PM on February 16, 2026, or sooner if conditions change significantly. Residents should also prepare for a higher tide scheduled for Tuesday morning, February 17, at 10:15 AM.
