Heavy Rain Event for the Eastern South Island 18 & 19th Oct.

Unread post by NZ Thunderstorm Soc »

Looks like many eastern SI places, especially south of Woodend Beach, may get a good fall of rain, starting tomorrow night and continuing into Tuesday and Wednesday and even including Central Otago.
I have never seen a heavy rain warning for Central Otago so that might be interesting.

GFS going for well over 100mm south of CHCH and about 75mm for Christchurch. Metservice saying rain developing tonight and heavy falls Tuesday and Wednesday for Christchurch, however, Tuesday looks pretty dry here and seems that Wednesday will be the wet day.

Hello all! According to someone who gets email from the Met service, more than 1 metre of snow is forecast for the high country tops on Tuesday!

Yes, although I think that's, 'from midnight tonight until early Wednesday morning that one metre of snow could accumulate above 1000 metres', according to this morn's 10:34am 'Snow Otago Warnings'. Lighter falls 'may fall as low as 600 metres'.

Its weird, GFS is going for 84mm for CHCH but on the GFS output maps (3 day rainfall) Metservice uses it looks like no more than 15-20mm...? I sent Bob McDavitt an email enquiring about rainfall from this event and he said christchurch could miss out altogether with some models indicating that and others suggesting around 20mm.

Currently fine and breezy northeasterly in Oamaru. Weather Warnings to the community have been issued by Civil Defence . Now we wait to see what happens. We are dry and could do with 25mm but the forecasted 100-150mm may be a tad too much

Not a drop yet in Dunedin
There is no such thing as bad weather, just the wrong clothes.

I finished all the lawns today but this afternoon did notice a nice line of developing castellanus to the north-west. Castellanus usually means a possible tendancy for thunderstorm development later.

The heaviest rain for the area is still hours away. Little bit of shower activity popping up on the radar now for here. Not going to get the sunny spells to allow for heating here. Dull with low cloud, southerly breeze and looks like it will start drizzling any minute.
