RAIN WARNING REMAINS IN PLACE FOR THE KAIKOURA DISTRICT – SOUTH TO AROUND GRETA VALLEY.

Good evening. It’s been a cloudy, cold and wet day for most. Gore Bay & Akaroa grabbed top spot today, with just 10 degrees; the full list of the daily ‘highs’ below.

Our heavy rain warning remains in place for all members; a warning issued over 4 days ago. The Kaikoura District remains most exposed to the heavier rain ‘feeds’, where grand totals may exceed 250mm about the hill country, by 6pm Monday; further south, we can also expect significant rainfall totals, to around Greta Valley (just north of Amberley). 

Rainfall of this magnitude has the potential to cause widespread flooding, slips and disruptions about the Kaikoura & Hurunui District, higher risk north of the Conway River. Risk of disruptions increases by late Monday; this system is just getting started in North Canterbury this evening.

For South & Mid Canterbury we can expect cloudy and cold conditions for the remainder of Sunday, with misty rain, drizzle and even some heavier rain at times, with freshening south-easterlies. Showers and rain will quickly clear south of Ashburton on Monday morning.

Rain will become more sustained tonight and overnight north of around Oxford, effecting most of North Canterbury and the Kaikoura District, persisting through most of Monday, with heavy falls north of around Amberley, the focus being on the Hurunui & Kaikoura Districts.

•Be sure to source your town page for specific rainfall totals over the next 24 hours – there will be significant contrast in rainfall totals.

LOW SNOW RISK STILL APPEARING.

•We’re also watching a very cold outbreak, late in the month, that may bring sleet to sea level and snow to very low levels across the region (100-200m). Keep up to date with our ‘Live Weather Feed’ for on-going coverage.

•July collectively looks colder and wet, with an increase in activity in the Southern Ocean and the possibility of more moisture ‘river feeds’ from the tropics.

Our complex low of interest continues to move south this evening, ‘feeding’ in widespread rain and drizzle risk across the region, falling as snow at higher elevations; significant above 1500m north of Mt Oxford.

Rain will continue into Monday, especially north of Ashburton, heavier and more persistent in North Canterbury (north of Amberley) before easing around evening.

Early and middle stages of next week look mostly fine, before rainfall chances increase during the second half of the week about the Main Divide & Canterbury Headwaters.

We continue to watch late in the month, with indication of bitterly cold southerlies and snow to very low levels.

Please source town pages for specific details and keep up to date with our ‘Live Weather Feed’ for all the very latest information.
