Ryan Drury, who lives in the central Ida Valley, said hail clogged his gutters and flooded his bathroom and hallway on Wednesday night.
"I’d just cleaned the gutters that morning because I knew there were some storms forecast.
"Some of the hailstones were about half an inch thick. It sort of kicked off at 7 o’clock."
Floodwater on Ida Valley-Omakau Rd was about 30cm deep in places, he said.
At 2pm yesterday a large pile of hailstones which spewed out of a downpipe had still not fully melted despite a hot and humid day, he said.
"And we’re bracing ourselves, because we’ve got thunderstorms brewing over the hills again."
Kaylee McNally of Poolburn, said the wind picked up about 6pm on Wednesday and a storm hit her property.
"I was standing, looking out and saw something fall from the sky. It was a big block of ice ... about the size of a 50c piece," she said.
"I’ve been here for 11 to 12 years and I’ve never seen anything like it — it was an almighty burst."
Mrs McNally said the corner of Auripo Rd and Ida Valley-Omakau Rd, close to Poolburn School, was badly damaged, but still driveable. The weather had lifted some of the road surface, which looked similar to earthquake damage.
Naseby was also hit with a rainstorm on Wednesday afternoon. Resident Marilyn Swinbourn said her property in the township was hit by 24mm in 35 minutes around 3pm.
Naseby Store owner Paul Bishop said there was minor flooding in the back of the store. There was no damage to his stock or freezers. Larchview Holiday Park owner Beth Connell of Naseby, said no facilities at the camp were damaged but the "big downpour" worried some campers.
Central Otago District Council roading services officer Mick Sparrow said yesterday no calls had come through to council offices about damage to any roads.
