The Environment Agency has issued a Flood Alert (Severity Level 3) for the Romsey Tadburn Lake area. The alert was officially raised at 10:38 PM on February 18, 2026, in response to rising river levels.

Affected Areas

The alert covers the Tadburn Lake Stream within the Solent and South Downs region of Hampshire. Specific areas at risk include properties located at the top of the river near Jenner Way and Sewards Rise. The Environment Agency notes that very high river levels may prevent water on the land from draining into the stream, increasing the risk to these locations.

Expected Conditions

Nearly 20mm of rain fell on February 18, 2026, leading to the current high river levels. Rainfall is forecast to continue for approximately four hours following the issuance of the alert. These conditions are expected to keep river levels and flood risks elevated throughout the night.

Timeline

The alert is effective starting from 11:00 PM on Wednesday, February 18, 2026. High river levels and flood risk will persist overnight and into Thursday, February 19, 2026.
