Alpine riverbed alert

Heavy rain has been falling since yesterday (Tuesday) afternoon in the headwaters of the major Canterbury alpine rivers (Rangitata, Rakaia, Waimakariri, Hurunui, and Waiau-uha). The rain is forecast to gradually ease throughout this afternoon (Wednesday). Flows are increasing in the upper parts of these rivers, and will increase in the lower parts overnight.

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