A Mild Start To Winter Likely

in many places for early winter.

towards below normal in the east of the North Island. Normal or below normal soil moisture levels and streamflows are
expected in the north and east of the North Island. Normal soil moisture levels and streamflows are expected in the
southwest of the North Island and over all the South Island.
