Used to be called the Pineapple Express. This is when the “Hawaiian High” pressure breaks down as it does and swings storms south and the “tail” of the storms can be seen off and around Hawaii. This happens about once every few years and then large break down like this about once every thirty to forty years.
It’s not unheard of.
I used to work with a couple meteorologists and also Surfline.com.
When Mom and Dad visited us in California, Dad would always joke about the “Pineapple Express.” He’s always say we were getting a “spritz of pineapple juice from Hawaii.” Dad always cracked me up. He had great humor.
