Severe weather over central and southern New Zealand, with heavy rain in the west and northwest gales in the east

A strong and moist northwest flow covers the South Island ahead of an active front over the Tasman Sea. This front, preceded by strong to gale northwesterlies, moves over the South Island on Tuesday, bringing significant heavy rain to Fiordland and Westland, including the headwaters of the Canterbury and Otago Lakes and Rivers. A heavy rain warning is in force for these areas. The front should then gradually weaken as it moves over central New Zealand on Wednesday.

A period of heavy rain is also expected ahead of the front in Buller, northern Westland and the north Canterbury headwaters, and a heavy Watch is in force for these areas.

This watch also covers the possibility that northwesterly winds may approach severe gale strength in Fiordland, Southland, Otago, Canterbury (except Canterbury High country which is already in the Warning), Marlborough, Wellington and Wairarapa south of Featherston.

People are advised to keep up to date with the latest forecasts as parts of this watch may be upgraded to a full warning, and additional areas are added.
