Alpine riverbed alert

Last updated: 1.33pm Thu, 25 Dec 2025

Heavy rain has been falling today (Thursday) in the headwaters of the major Canterbury alpine rivers (Rangitata, Rakaia, Waimakariri, Hurunui, and Waiau-uha). The rain is forecast to continue throughout the day before easing overnight. Flows are beginning to increase in the upper parts of these rivers, and will increase in the lower parts from this evening.

Beware of increasing flows if you are working or recreating in these riverbeds. Out-of-river flooding from any of these rivers is unlikely. This message will only be updated if the situation changes significantly. Merry Christmas!
