A wave of Saharan dust currently blankets the central Caribbean and is set to affect Jamaica as of Wednesday morning, ushering in hazy conditions for residents.
Satellite Observations and Forecast
According to Jamaica’s Meteorological Service, satellite imagery reveals a thin layer of dust originating from the eastern Caribbean.
Drifting westward, this dust mass, although lighter than previous occurrences, is poised to traverse the island starting Wednesday morning and lingering until midday Thursday.
This phenomenon coincides with the approach of a tropical wave nearing Jamaica’s vicinity.
Regular weather phenomenon
This annual weather event, typical between May and October, sees these plumes typically dissipating within a week.
The recent passage of a dust plume last week into Monday further underscores this cyclical pattern.
Comparison with past events
Addressing comparisons to the notable June 2020 event, meteorologists note that this current dust layer is “not of a similar magnitude and the hazy conditions will be short-lived with the greatest concentrations just south of the island.”
Given the forecasted presence of suspended Saharan dust particles, particularly cautious measures are advised for individuals with asthma, allergies, or respiratory ailments.
Ongoing monitoring and weather outlook
Continual monitoring of this Saharan dust layer remains a priority for the Meteorological Service.
Meanwhile, as of their latest update at 5 am on Wednesday, June 26, 2024, the Met Service reports a prevailing trough across Jamaica, anticipated to persist until Thursday with the impending passage of a tropical wave.
Enhanced windy conditions are also expected, attributed to the influence of the low-level jet stream in the region.
