HONOLULU (HawaiiNewsNow) -- As Hurricane Lane nears, some parts of the state have already seen more than a foot of rain in the past 24 hours.
Waiakea saw 18.82 inches of rain in the 24-hour period ending at 8:45 a.m. Thursday.
Hilo Airport has seen nearly 15 inches of rain in the same period of time.
For some perspective, the historic flooding in April brought nearly 50 inches of rain to Kauai in a 24-hour period. According to The Weather Channel, last year's deadly Hurricane Harvey brought almost 30 inches of rain in a 24-hour period to Texas.
The torrential rains on the Big Island triggered widespread flooding, including along Hilo's Bayfront.
According to the National Weather Service, rainfall is expected to slow down for the Big Island as the hurricane moves on to other islands.
But forecasters are urging residents not to let their guards down.
"Heaviest rain spans are starting to clear the Big Island, but definitely flooding is still a concern for the rest of the day today and throughout tomorrow," said Melissa Dye, a meteorologist with the National Weather Service.
There are no reports of buildings or homes flooding on the Big Island at this time.
Big Island Civil Defense officials say they hope the low-lying areas on the eastern side of the island are able to drain properly soon before homes are sffected.
As of Thursday morning, the most rainfall that Maui saw was 4 inches in the West Wailuaiki area in a 24-hour period.
