    Looking Ahead

    Breezy trade winds are forecast to strengthen slightly Thursday through Friday, then slowly weaken again over the weekend. An area of enhanced moisture will cause showers to increase over windward areas Thursday and Thursday night, followed by a drier pattern on Friday. Showers are forecast to increase again during the weekend as a disturbance moves slowly westward over the islands. Winds are forecast to weaken again early next week, with a very warm and humid land and sea breeze pattern prevailing.
