Hail fell in Niu Valley and Aina Haina at about 9:30 a.m. and also fell over Waimanalo this morning.
Bob Chuck, who lives on Opihi Street in Niu Valley, said hail the size of peas "came down in pellets" and covered his backyard in what looked like a blanket of snow.
"It’s very, very unusual," Chuck said, noting that the last time he saw hail was when he attended Michigan State University in 1948 and Cornell University a year later.
"I never had it in my backyard," he said.
Aina Haina resident Robert Allen said grape-sized hail fell about 9:30 a.m. at his Akilolo Street home.
"It sounded like rain hitting a tin roof, except we don’t have a tin roof," he said.
