Heavy rain in South Canterbury

The heaviest falls so for from the system pushing into the east coast of the South Island have been in South Canterbury. More specifically around Peel Forest, Geraldine and the ranges behind there.

About Geraldine forest 146mm has fallen since yesterday morning, 143.5mm at Mt Frances and 80mm in Blandswood which is a small settlement near Peel Forest.

Conversely river flows in the area have increased dramatically as well. The Orari River at the gorge has gone from a mere trickle yesterday morning at 3 cubic meters per second rising to 400 cubic meters per second currently which is at it’s peak so far.

The Opihi River at the SH1 bridge has gone from 4 cubic meters per second up to a massive 722 cubic meters per second currently which is at it’s peak also and still climbing.

The rain is definitely heavy in the above areas, hopefully there aren’t to many issues in regards to flooding.

Rain is starting to clear the east coast of the North Island north of Wairarapa at the moment and in Auckland a new round of heavy showers is about to move in, in between many have had a spot of sunshine.
