The Adverse Weather Alert
As forecast, showers and isolated thunderstorm activity have mostly affected eastern and southern Trinidad over the last 12 hours, with additional activity forecast for the southern half of the island on Sunday.
This is due to a shearline in place across T&T, following the passage of a tropical wave. However, strong wind shear remains, so higher rainfall totals will continue to favor Eastern Trinidad through today.
The Trinidad and Tobago Meteorological Service has issued an Adverse Weather Alert Yellow Level on Sunday morning at 7:21 AM, which went into effect at 7:00 AM Sunday 22nd November 2020, and will remain in effect through 6:00 PM Sunday 22nd November 2020. This is in line with our forecast, as a high-pressure ridge becomes dominant tonight, bringing mostly settled conditions with brisk showers into Monday.
Trinidad and Tobago is not under any tropical storm watch or warning at this time.
