    The 2022 Wet Season has officially begun, according to a declaration by the TT MET Service.

    This start is marked by measurable rainfall produced by a Tropical Wave and/or the Inter-Tropical Convergence Zone, both of which are the main weather-producing features of T&T’s wet season.

    The TTMS says it has been monitoring a Tropical Wave that moved across both islands on Sunday into Monday.

    Although this is the fourth Tropical Wave that has moved off the west coast of Africa and traversed the Tropical Atlantic, it is the first one to affect T&T.

    As at 8am today, the month of May has yielded rainfall totals of 28.5 mm, which amounts to 23% of the average total rainfall of 124mm for May.

    The TTMS says the remainder of the month is likely to continue with below average rainfall across most areas.

    It adds that, at this time, there are no Tropical Waves over the Tropical Atlantic, so no wave activity is expected for at least the next week or so.

    Meanwhile, the ITCZ remains south of latitude 5N, but is expected to gradually migrate northward as the month progresses.

    La Niña

    The TTMS says with the current La Niña phase, this means favourable conditions for increased cloudiness and rainfall.

    It says while the ongoing La Niña has influenced the local climate in an unusual way, there is likely to be a slow build up to the wet season rainfall.

    Regardless, the TTMS urges the population to prepare for managing the expected weather instability that comes with the wet season.

    Climatologically, Trinidad and Tobago’s wet season can extend into December before completely transitioning into dry season in January.

    Please be reminded that the Atlantic Hurricane Season officially starts from June 1st and extends until November 30th.
