Flooding possible. Be prepared.
High river levels may lead to flooding.
River levels are high but currently falling on the Swill Brook. Flooding of low lying land and roads is expected to continue today, 12 February 2026, especially in the Oaksey area. Further rain is forecast over the next 24 hours, which has the potential to be heavy at times. River levels are forecast to rise again in response to today's rainfall. We expect levels to remain high over the next couple of days.
We are monitoring rainfall and river levels. Avoid low lying footpaths and roads near rivers, which may be flooded. Go to River Levels online for updates on current river levels.
This message will be updated by 12:00PM on the 13 February 2026, or as the situation changes.
