Another low pressure system in the southern Tasman Sea will send a secondary surge of rain and showers northwards up the western coastline of both islands for the following two days.

For the South Island’s West Coast expect rain to set in with a few heavy falls.  Some spillover is possible into eastern areas, although nothing substantial. 

The low, parked near Fiordland, is in no hurry to move – basically stalling for all of Wednesday and much of Thursday, meaning rain for the West Coast will set in and further north, up the North Island’s western coastline, showers are more likely.

For eastern areas of the South Island a few spits are possible but places like Christchurch should stay mainly dry over the coming two days with most of the energy on the other side of the Southern Alps.  Eastern areas of the North Island should be mostly dry and warm.

Temperatures for most places will be mild over the next 48 hours.
