A wet day is on the way for the western South Island today.  A front will move very slowly onshore and combine with plenty of moisture to keep rain going throughout the day for the West Coast and Nelson.  Heavy rain is also possible.

A few showers are also expected about Marlborough and northern Canterbury today.  Showers could develop for the rest of the South Island later this afternoon and tonight.

The North Island will fairly cloudy today, but should remain dry during the daylight hours.  Showers may develop well after dark tonight.  The best chance for that will be about Northland, Auckland, the Bay of Plenty, Taranaki and the Central Plateau.

The front will continue its eastward trek tomorrow and bring rain to most of the country.
