Showers Expected This Week [5-Day Weather Outlook]

According to the Trinidad and Tobago Meteorological Service (TTMS), no significant features for tropical cyclone development are expected during this outlook period. However, a series of weak perturbations are expected to cause intermittent increases in surface convergence and moisture advection across Trinidad and Tobago, the Windward Islands, and the Southern Leeward Islands, during this outlook period.

Looking Beyond This Outlook Period

• At this time, looking ahead in the Area of Interest during the seven (7) days following this outlook period, there are no significant features nor cyclonic developments analyzed.
• These early analyses so far into the future are subjected to much variation as time progresses. The Met Office said it will continue to analyze and monitor all developments, or possible developments, within our Area of Interest.

Seas

• The wind waves in the open waters to the near-East and Northeast of Trinidad and Tobago are expected to be near 2m during this outlook period.

Wind

• The wind in the near-surface to the lower mid-level over Trinidad and Tobago and the Southern Windward Islands (2,000 ft to 5,000 ft), is expected to be 15 kts to 20 kts but increasing to 25 kts by Saturday evening (8th). Direction is expected to be mostly between East and East-Northeast until Thursday (6th), after which it veers from East to Southeast for the remainder of this outlook period.

Dust

• Mild to moderate dust concentrations are expected in the atmosphere during this outlook period. Sensitive persons are advised to take the necessary precautions.

Synopsis And 5-Day Outlook

• A series of weak perturbations are expected to cause intermittent increases in surface convergence and moisture advection across Trinidad and Tobago, the Windward Islands, and the Southern Leeward Islands, during this outlook period.
• The surface convergence and moisture build-up, interacting with local dynamics, are likely to enhance the probabilities for isolated heavy showers or thunderstorm development, especially over Trinidad and Tobago and the Southern Windward Islands on Tuesday (4th) and Wednesday (5th).
