🌧️ Latest update on how we are shaping for Wednesday to Thursday ❄️
While this remains a complex system, we are however seeing models dropping back in terms of snow accumulations, snow still remains a risk for late this evening and into Thursday morning for areas above 700m, where the more significant totals may be, with a more light accumulation risk down to 400m
The really cold air that was suggested yesterday has weakened and pushed more out to east, which can limit the amount of snow we may receive from this system, which has also dropped rainfall totals.
💦 We can expect plenty of rain throughout Wednesday with some heavy falls at times.
There is a risk of some flooding in pockets from this system, one to keep in mind of.
Burkes Pass and Lake Tekapo may see accumulations around 10 to 20cm tops at this stage, which is a significant back drop, compared to how it was looking with yesterday model runs!
Mount Cook Village remains the most exposed to the heaviest moisture, transition from heavy rain to snow and its timing will be critical, which 20cm+ still a risk there.
Twizel is more around 2 to 5cm at best currently.
Timing of the transition of rain to snow and the difference of temperature by 1 to 2 degrees is vital for today in whether you get big snow or less.
Throughout today we will be keeping an eye on things and update as things unfold 👀
