“We have about 40 amateur radio operations out there right now that are doing field observations, supplementing police and fire that are on the ground as well and reporting what they’re seeing as far as rain and other conditions,” said Darryl Oliveira, Hawaii County Civil Defense administrator.

"Hawaii Island continues to see rain from Hilda.

"On Friday afternoon, both leeward and windward areas saw sporadic heavy rain from South Kona to Honaunau and Pahala to Naalehu.

"Kona rains should subside Friday night, but the Hilo side can expect rains to continue into the evening.

"A flood advisory is in effect for parts of the island until 8:30 p.m. Friday, and a flash flood watch continues through late Friday night.

"Yesterday much of the rain was focused over the east and southeast coastlines as Hilda weakened to a remnant low.

"Areas such as Waiakea Uka saw over six inches of rain and Hilo had over three inches. Valerie Victorine shared video of a gushing Rainbow Falls.

"However, no major flooding problems have been reported and officials hope it stays that way.

"Three charter schools were closed Thursday as a precaution: Na Wai Ola, West Hawaii Explorations Academy, and Kau Learning Academy.

"The National Weather Service extended a flood advisory for most of Hawaii County until 6:30 p.m.
