Alert Details
The Environment Agency has issued a Flood Alert for the River Thame, Horsenden Stream, and Chalgrove Brook. The alert was officially raised at 10:37 AM on February 18, 2026, following reports of high river levels that may lead to flooding.
Affected Areas
The geographic scope of this alert includes regions within Buckinghamshire, Hertfordshire, and Oxfordshire. Specifically, flooding of low-lying land and roads is expected to continue today in the Thame, Stadhampton, and Dorchester areas. Officials also expect river levels in the Aylesbury area to rise in the coming 24 hours.
What You Should Do
Residents are advised to avoid using low-lying footpaths and roads near rivers, as these areas are susceptible to flooding. The Environment Agency recommends that individuals monitor the situation by checking the River Levels Online service for real-time updates on current conditions.
Expected Conditions
River levels are currently high on parts of the River Thame. While weather forecasts indicate predominantly light rain for the afternoon of February 18 and overnight, this precipitation may be heavy at times. Consequently, river levels along the rest of the river are expected to remain high over the next several days.
