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.

Residents in the warning area are advised to consider activating any flood protection products they may have. The Environment Agency is currently monitoring rainfall and river levels and will ensure the river is kept free of reported blockages to mitigate risk.
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.
