Our friends in Hanalei are used to flooding ....at least 6 major floods in the last 14 years. The mouth of the Hanalei River, at the end of Weke Rd., is shoal. And when it rains and rains on the slopes of Mt. Waialeale, reportedly one of the wettest places in the world, much of runoff fills the Hanalei River which backs up on the entrance shoal and overflows into town..
It happened again Tuesday, 8-12" of rain in 24 hours, and 22" measured on Mt. Waialeale. Hanalei Bridge over the River was closed for an extended time, and 150 people sheltered at the Hanalei School. As well, a rare tornado came ashore near Barking Sands on the west shore.
