The Adverse Weather Alert Discontinuation
The Trinidad and Tobago Meteorological Service discontinued the Adverse Weather Alert (Yellow Level) on Monday at 11:07 AM.
The TTMS states, “The potential for impactful weather associated with the passage of a Tropical Wave has significantly diminished. However, there remains a medium (40-60%) chance of the heavier shower or isolated thunderstorm activity, favouring Southern Trinidad. In the event of a heavier shower or thunderstorm, gusty winds can occur.”
This “alert” status considers the possibility of the event ending, with certainty at its second-lowest level, at “possible”. Discontinuations and green-level alerts have historically been issued with a likelihood of ‘very likely/observed’ or ‘likely’.
The alert’s color indicates the severity of the event and the probability of its occurrence. Currently, the alert level is green. This means that the hazards are still possible, and the severity of the impacts is moderate for this particular alert. You should remain aware of the hazards in your area, which are primarily associated with street or flash flooding, gusty winds exceeding 50 km/h, possibly falling trees, landslides, and agitated seas.
A moderate Adverse Weather Alert can result in possible injuries and behavioral changes, which are necessary to ensure safety. Minor property damage may also occur, temporarily disrupting income-earning activities and affecting several communities.
The Met Office advises the population to monitor official news sources and weather updates and follow the instructions of government officials.
