Saharan dust concentrations will continue move across St. Vincent & the Grenadines, reducing in intensity as the week ends. Small craft operators and persons with respiratory concerns should continue to exercise caution for low visibility and poor air quality. Weak pulses may trigger some shallow brief isolated showers over next 24 hours whereas a few early morning and afternoon showers are anticipated on Saturday ahead of a tropical wave. By Sunday, instability trailing the wave would be affecting the islands.
