West Coast in for days of rain

UPDATED 6:36am — On Wednesday we are about to see things ramp up a few notches, with a very wet northwesterly airstream over the country.

This will result in what will probably be torrential rain for the West Coast of the South Island, right through the Southern Alps into the eastern divide a little.   As of 6:30am rain was only patchy – but it is likely to intensfy and for some parts of the West Coast, especially in the mountains, flooding rains are possible.  Government forecast MetService now says up to half a metre of rain might fall.

A front slowly then moves northwards up the South Island, before reaching the lower North Island later on Thursday.

While flooding is not forecast to be widespread, much of the West Coast is exposed to the possibility of torrential rain over the next 24 hours and all Coasters should be aware of the latest warnings and watches issued by MetService.

For most other places – today is business as usual for mid-Autumn.
Winds ahead of the front are typically a strong north-norwesters, then easing after the front clears.

Winds may tend a little more to the west after the front moves through, but there isn’t a lot of a major wind change with this front – just rain activity in the main.
