The MetService reported more than 26,000 lightning strikes in about 12 hours overnight on Sunday - almost 10,000 of them between midnight and 2am.
The lightning was accompanied by loud, unrelenting claps of thunder and intermittent downpours of rain, which delivered about 9mm of rain overnight.
That forced Coronet Peak to close yesterday so the saturated snow pack could dry out ahead of its final week of the 2017 season.
Although the Remarkables skifield opened yesterday, the Shadow chairlift was closed due to ``weather and snow conditions'' and the Sugar chairlift was on hold due to high winds.
The storm also briefly affected power in the district. An Aurora Energy spokesman said there had been a 3-second trip on the feeder between Hawea and Makarora at 2.47am yesterday as a result of the storm.
It is understood there was a separate Transpower trip early yesterday which affected some Queenstown consumers.
