Forecasters are watching Tropical Storm Darby closely, and say the cyclone could bring rain and gusty winds to the state this weekend. The storm hasn’t yet crossed into the Central Pacific, and is expected to continue weakening over the next several days. But meteorologists say the storm could still pack a powerful punch when it comes closer to the islands Saturday. "Most of the systems we’ve had so far have turned to the north into colder water before they got to the islands," said Robert Ballard, a meteorologist with the National Weather Service. "That may not happen in this case."
