For the last few days, it’s been pretty obvious that there was going to be at least some heavy rain showing up today. The western regions of the South Island seemed to be the most likely candidates for getting heavy rain. Eastern Bay of Plenty and Northern Gisborne seemed likely to see heavy rain as well.
Now that the incoming low is really starting to show its hand, it’s becoming much clearer where the heaviest rain will fall. Potential rainfall amounts are also become clearer and it looks like they are going to reach warning criteria in some areas.
So, Government forecaster MetService has gone ahead and issued the following warnings for heavy rain:
Heavy rain is also possible about the lower and western North Island. However, it’s more likely that wind will be a problem. Severe gales are possible about southern Taranaki, inland Wanganui and Taihape this afternoon. Any heavy rain is likely to be associated with thunderstorm activity that may develop.
The main risk for thunderstorms will be from Northland and Auckland through to Taranaki this afternoon. There is also a chance for thunderstorms for the Kapiti Coast this afternoon, but the risk is very low.
Road snow warnings for Porters Pass, Lindis Pass and Arthurs Pass are expected to be lifted early this afternoon as snow turns to rain.
