The tropical disturbance is not expected to produce much in the way of wind, and sustained winds are expected to stay below the 20-knot threshold for a Small Craft Advisory. Exercise caution headlines may be needed, but even that looks marginal right now.

Background wave heights will be between 2 and 4 feet. $$
