A large low is crossing NZ pushing rain into Canterbury, snow in the mountains and downpours for the north of NZ.
Generally speaking most parts of NZ actually don’t have severe weather – but exceptional rainfall totals are still expected in the eastern South Island (Canterbury). Check your local rainfall totals at WeatherWatch or RuralWeather – some in Canterbury are quite significant.
For example, Mount Somers has 160mm forecast for today only.
Darfield and Ashburton have just over 100mm forecast for today.
Christchurch has a much lower total of 34mm for today.
The most up to date information (like rainfall, temperatures and wind speeds/direction) can be found in your LOCAL forecast at WeatherWatch.co.nz or RuralWeather.co.nz – IBM crunches NZ and global data hourly.
Heavy rain is expected to continue in Canterbury with flooding and slips possible. Snow will be heavy in the mountains and ranges – over 1 metre possible before Tuesday.
A few isolated thunderstorms will affect the North Island with a few heavy falls.
We’ll have an even more detailed forecast again by mid morning as we crunch the very latest data and bring you more detailed maps to help explain the next 48 hours.
In the meantime, many maps and extra details can be found in our MAPS section.
