The Adverse Weather Alert Discontinuation
The Trinidad and Tobago Meteorological Service discontinued the Adverse Weather Alert (Yellow Level) on Thursday at 10:12 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%) chance of the heavier shower or isolated thunderstorm activity, favoring Southern Trinidad. In the event of a heavier shower or thunderstorm, gusty winds and street flooding 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 Met Office advises the population to remain vigilant and monitor weather conditions. At this risk level, there is a low risk to public safety, lives, livelihoods, and property.
