Source: loop Caribbean
A significant Saharan dust surge is expected over the weekend with a dust advisory being issued for the eastern Caribbean and northern South America. This is according to the Caribbean Institute for Meteorology and Hydrology (CIMH).

The Weather Research & Forecasting-Chemistry (WRF-Chem) model run by CIMH Dust & Air Quality Forecasting Centre, shows an imminent dust incursion is expected to affect the eastern Caribbean and northern South America over the weekend with the most intense area of the dust plume impacting these areas around February 24.

The forecasted elevated dust levels are expected to exceed the outdoor air quality guidelines established by the World Health Organization (WHO).

Already several meteorological offices in the Caribbean have issued statements on the Saharan dust.

The St Vincent and Grenadines Meteorological Service in its 72-hour weather outlook said a plume of Saharan dust is approaching the islands and concentrations could vary across SVG during the weekend, with moderate/thick haze overnight Saturday. It advised the public to be alert.

It said small craft operators should exercise caution for reducing/poor visibility in moderate/thick haze across the islands, especially during Saturday night.

The Dominica Meteorological Service in its weather update on Saturday said a ridge pattern along with a thick plume of dust haze is expected to become the dominant feature. It said people with respiratory sensitivities are advised to take all the necessary precautions to avoid complications.

The Trinidad and Tobago Meteorological Service said a brief but significant increase in Saharan dust concentration is expected to impact air quality overnight.
