The Geminid Meteor shower is currently active. Peak nights are Dec. 12-13 and 13-14.
Looking Ahead
Winds are forecasted to increase Wednesday and Thursday as a front moves across the islands. This weak front is not expected to be a huge rain-maker but light showers will favor windward and mauka areas. The timing of this front brings it to the Big Island Thursday. Moisture from the front is expected to linger around Hawaii County through the end of the work week for windward areas. Winds will fill in behind the front out of the north then northeast, turning easterly by Friday. A second stronger front expected next weekend is forecasted to reach Hawaii County Sunday night and Monday and will bring strong and gusty winds in its wake.
