High pressure, the weather feature that generates our trade winds, is moving away from the islands and as that happens our winds are expected to weaken. Over the next few days that will be the trend. Another high pressure system will move in by Thursday bringing our winds back up to breezy. 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.
