The peak nights for the Geminid Meteor Shower have passed but the shower is still active until December 19. Details on timing and viewing tips can be found HERE.
High pressure, the weather feature that generates our trade winds, is moving away from the islands and as that happens our winds have weakened. Another high pressure system will move in this evening bringing our winds back up to breezy overnight and into Thursday. Over the weekend we expect winds to shift out of the southeast. A front is expected to impact the state early next week. Will keep an eye on it.
