A snow-hit Milford Road is closed again on Friday, as heavy rain has heightened the avalanche risk in the area.
It's the third time conditions have affected State Highway 94 this week. The alpine road reopened this morning but was shut again from East Gate (Hollyford Road Junction) to Donne River Bridge (Westgate) at 5pm.
The avalanche hazard had been at low for most of the day but was raised to moderate by 5pm, due to forecast rain overnight and into Saturday morning, the Milford Road Alliance advised.
The highway was expected to open again mid-morning on Saturday once an avalanche hazard evaluation was completed.
"Please take extra care."
A heavy rain watch was in place for Fiordland from tonight. MetService said periods of heavy rain were forecast from 9pm tonight until 7am tomorrow, and the amounts may approach warning criteria. More heavy rain was expected from Sunday until Tuesday.
Heavy rain was also expected about the headwaters of the Otago lakes and rivers from 10pm on Friday until 6am on Saturday. Rainfall amounts may approach warning criteria within 15km east of the main divide.
Strong winds were likely for Southland, northwest of Winton and Fiordland, as well as the Queenstown Lakes district and Central Otago, west of Alexandra, from midnight on Friday until 6am tomorrow. North to northwesterly winds may approach severe gale in exposed places.
