We were in Oahu and Maui and left Maui a day and a half early to avoid tropical storm Darby. There were 2 more tropical storms in the area before Darby during our time in Hawaii- Blas and Celia-- we were on Oahu at Aulani during those times. From everything we heard, typically the tropical storms hit cooler water, weaken and then their path spins off away from Hawaii. I don't know that there was even rain from Blas, and all we got from Celia was some mostly light rain showers (with a couple of short downpours thrown in) off and on for a day at Aulani. . We didn't mind the rain at all by the pool and on the beach as it cooled things off and we were wet anyway- and there were plenty of breaks with sunshine in between the little showers- but it did move the characters from their outdoor locations for part of the day and unfortunately resulted in the Starlight Hui show being cancelled that night. From what we heard, this was what typically happens with tropical storms and the extent of what you should normally have to deal with. Darby was the first time a Tropical Storm actually directly hit Hawaii in 2 years. It apparently was also kind of a surprise that it hit Oahu after Hawaii. When we were there after they were pretty sure it was not going to turn as they usually do, the newscasters were all saying it was going to hit Hawaii and Maui hard and probably not have much if any impact on Oahu. We were gone before it hit, but from what I have found on the internet, it looks like it hit Hawaii and Oahu and just skirted Maui. We talked to a guy who had lived on Maui for years, and he said that usually if tropical storms do hit, they hit Hawaii (big island), then slow down after they hit land/mountains there and barely have an impact on Maui or the other islands. The one thing that did happen with Celia while we were at Oahu and in the days when Darby was approaching while we were in Maui was that the currents at the beach get significantly stronger, so you have to be really careful with that.
