A WILD EVENING FOR MANY AREAS – ISOLATED THUNDERSTORMS ( HEAVY RAIN & SNOW TOMORROW.)

Alpine road snowfall warning & heavy snow warning in place.

Good evening. Conditions are gradually starting to deteriorate in the south, with isolated thunderstorms turning to more widespread rain. There is still the chance of potentially damaging hail and severe thunderstorms until around 8:30pm. We have a confirmed sighting of  a tornado just out of Ashburton – no significant damage was recorded.

Showers & rain will become widespread for a time later this evening and we can expect snow to briefly lower about the hills this evening. Kaikoura grabbed top honours today with 21 degrees, while Arthur’s Pass Village recorded just 12 degrees. (Full list of daily ‘highs’ below.)

Our eyes are now fixed on Monday & Tuesday with widespread rain, potentially heavy falls and snow to low levels about the Canterbury Foothills.

All our towns have been moderated and cater for this prolonged period of wintry weather.
