From Sunday, the Saharan dust concentration in the atmosphere is expected to increase.

In its 5-Day Weather Outlook, the TTMS says levels will become moderate and high at times, for the period ending on Wednesday.

Sensitive persons are advised to take the necessary precautions.

Brief  Synopsis

The north Atlantic high pressure cells will continue to produce mostly ridging of high pressure across Trinidad and Tobago and the windward islands throughout this outlook period. The surface winds continue to be moderate, steady and generally easterly across the equatorial Atlantic. This is expected to cause the mechanical turbulence, together with some surface convergence, which would produce intermittent bands, or patches, of cloudiness moving across Trinidad and Tobago and the lesser Antilles. On Wednesday (28th February 2024) the passing of a frontal system to the north of the Lesser Antilles is expected to induce a low to mid-level perturbation which is likely to cause an increase in moisture convergence over Trinidad and Tobago and the Windward islands.

Generally fair and hazy conditions are expected for most of this outlook period, with intermittent patches of clouds, producing mostly brief, light or moderate, showers over varying areas, with the chance for isolated heavy showers to occur, especially near hilly areas.
No major precipitation event or significant rainfall accumulations on the synoptic scale is predicted, but in interactions with the land topography and local dynamics there is the possibility for isolated, moderate or heavy, showers to develop, especially near hilly areas.
A long and relatively straight fetch across the equatorial Atlantic is expected to remain therefore winds out of the north Atlantic high pressure cell are likely to continue to be moderate and steady throughout the outlook period.

⚠ 𝑺𝒂𝒉𝒂𝒓𝒂𝒏 𝒅𝒖𝒔𝒕 ⚠
From Sunday (25th February 2024) Saharan dust concentration in the atmosphere is expected to increase to moderate, becoming high at times, for the remainder of this outlook period. Sensitive persons are advised to continue to take the necessary precautions.

𝟓-𝐝𝐚𝐲 𝐎𝐮𝐭𝐥𝐨𝐨𝐤

S𝐚𝐭𝐮𝐫𝐝𝐚𝐲 (𝟐𝟒𝐭𝐡)
Mostly fair and hazy, with patches of moisture advection, during the morning to early afternoon, likely to produce a few brief, light to moderate, showers over some areas and a 10% chance for a heavy shower. Mostly fair and hazy afternoon, evening and night. Winds generally from the east-northeast to east.

𝐒𝐮𝐧𝐝𝐚𝐲 (𝟐𝟓𝐭𝐡)
Fair and hazy early morning. Patches of moisture advection during the late morning and afternoon, interacting with the land topography and local dynamics, is expected to produce some light to moderate showers over varying areas. There is a 20% to 30% chance for an afternoon heavy shower to develop in some areas. Mostly fair and hazy evening and night with the chance of a brief shower. Winds mainly from the east.

𝐌𝐨𝐧𝐝𝐚𝐲 (𝟐𝟔𝐭𝐡)
Moisture advection, initially over Tobago during the early morning and eventually over both Trinidad and Tobago from late morning to afternoon, is expected to interrupt hazy and dust conditions, with light to moderate showers over varying areas. There is a 20% to 30% chance for an afternoon heavy shower to develop in some areas. Fair and hazy evening and night with brief showers in some areas. Winds mostly east to east-southeast backing to northeast during the evening and night.

𝐓𝐮𝐞𝐬𝐝𝐚𝐲 (𝟐𝟕𝐭𝐡)
Mostly hazy and dust conditions. Brief showers favouring the western peninsulas of Trinidad and hilly areas of Tobago are likely with a 10% to 20% chance for an isolated heavy shower. Hazy to dust conditions during the evening and night. Winds initially from northeast veering to east by late morning into afternoon and back to northeast during the evening and night.

𝐖𝐞𝐝𝐧𝐞𝐬𝐝𝐚𝐲 (𝟐𝟖𝐭𝐡)
Mostly fair and hazy to dust conditions during the early morning. A passing low level perturbation is expected to cause an increase in moisture convergence, initially over Tobago from early morning, and eventually over both Trinidad and Tobago from late morning, with a light to moderate shower over varying areas. There is a 20% to 30% chance for a heavy shower to develop, favouring Tobago and northern and western areas of Trinidad. Wind initially from northeast veering to easterly by late morning and backing to northeast during the evening and night.
