HONOLULU (HawaiiNewsNow) - A combination of weather factors contributed to the pyrotechnic storms and the twin waterspouts that formed yesterday.
According to Mike Cantin of the National Weather Service, an upper level pool of cooler than normal air, combined with warm rising air and heat from the lack of tradewinds helped to form the thunderstorms and waterspouts.
Cantin also spoke about the strength of waterspouts, saying they can produce winds up to 80 mph.
He also talked about the threat from lightning saying "When thunder roars, go indoors."
The system responsible for the storms is expected to weaken by Wednesday, but linger in our neighborhood through the weekend bringing in scattered showers.
