Aloha!
Simple one today. Celebrate Check the Precipitation Amount in Hawaii Day by going to your favorite weather or news site and looking around for how much it rained (or snowed) in Hawaii.
No, wait!
Maybe this means you should go to Hawaii and check the precipitation today.
Hm. That could be more interesting.
Plane (or boat) tickets. Time off work (aka vacation). Packing. Unpacking. Sunglasses. Suntan lotion. Hula skirts. Dancers in hula skirts.
Whichever you decide to do - weather site or trip to the state that technically has an apostrophe in it for some reason - do it well and accurately. We don't want any sloppy checking of rainfall amounts here.
Spoiler alert: There isn't much variation in precip from day to day in Hawaii. It rains virtually every morning and is sunny virtually every afternoon.
Book 'em, Dano.
