Trade winds are forecast through next week. Locally strong trades will ease slightly over the weekend. Rainfall will also decrease over the next couple of days as moisture and instability decrease. Showers may become more active again next week as the atmosphere becomes less stable and remnants of an old front may ride in on the trades.
