However, sustained surface winds of between 40 to 50 knots (45 to 55 mph/73 to 89km/h) with higher gusts on the northern periphery of the potential storm are expected to impact Barbados late Monday into Tuesday morning.
In addition, large easterly swells of at least 5 to 6m (16 to 20 ft) are also forecast to accompany the system. Thus, a High-Surf Advisory and Small-Craft Warning has been issued and will be in effect from 6 a.m Monday, June 19.
