State Highway 94 has closed intermittently during spring, as snow has been softened by heavy rain, making the area unstable.
MetService said heavy rain with squally thunderstorms and hail were possible throughout Thursday, with strong northwesterly winds gusting to 90kmh.
Snow showers were expected about the Homer Tunnel from Friday until Monday, the Milford Road Alliance advised today.
"Access along the Milford Road with the current weather pattern is providing both road level snow and avalanche hazards from Thursday to Monday."

It was expected to reopen late on Friday morning, once road and avalanche inspections have been undertaken, along with potential snow clearing, Milford Road Alliance said.
"From Saturday to Monday, road users should plan for daytime travel only from mid-morning until 5pm."
Motorists should allow extra time for snow clearing work.
