Main Kaua‘i forum must have a dozen threads regarding the recent flooding and this makes one more. No issues in Kapa‘a at all. By the end of May, probably no issues anywhere on the island with the exception of the Kalalau Trail - did you plan on hiking it? If not, no worries. There's plenty of places on Kaua‘i that you can't drive to, to begin with, so the helicopter will be a great tour.
I live in Kapaa, we're fine!!
We’re here in Kapaa for two weeks. It’s business as usual. We love it here. Thought about canceling as well but made some phone calls and felt comfortable along with a full flight coming here. As previously posted, Hanalei is off limits but so many other places to go. NO NEED TO CANCEL. Hey, they are working very hard here. Lucky your vacation is the end of May. Should be in much better condition when you arrive..
Please don't tell visitors that Hanalei is off limits. Its not. There are very few businesses that have not opened. Businesses need you to come and parts of the bay are open. They are just asking that you stay away from the boats landing and grabbing supplies for those still in flood areas. Hanalei Town is so cute and people should see it.
