Rain and storms spread throughout NZKim Westcott, Friday January 8, 2016 - 15:46 EDT
The intense system which saw days of heavy rain along Australia's eastern seaboard has crossed the Tasman.
Yesterday, western parts of the South Island saw falls in excess of 100mm. Today, a further 40-80mm is likely although rainfall is wonâ??t be as intense.
The North Island can expect heavy and thundery downpours today, with falls in excess of 100mm expected along the southern ranges as well as and parts of the Bay of Plenty. There is a current severe thunderstorm watch for locations north of Napier and New Plymouth including Taupo, Waikato and Auckland. Thunderstorms have already brought near 20mm in an hour around Auckland.
Parts of the Marlborough, Wellington and Wairarapa may also experience gales, potentially as high as 140km/h. Wind gusts may be even higher, especially about exposed locations such as the ranges or coasts.
This low pressure trough is moving rapidly, and the most intense rainfall and winds will clear by late this evening.
After the wind and rain associated with the trough has passed, a set of cold fronts will bring a surge of cold and gusty winds and further showers along the South Island this weekend.
Early next week, there are some indications that the North Island will get a drenching as the remnants of Ex-Tropical Cyclone Ula pass to the north.
