Meteorologist: Expect wetter than normal start to dry season


    Expect a wetter than normal start to the dry season, thanks to the “triple-dip” La Niña, according to a meteorologist.

    According to the World Meteorological Organization this phenomenon is where there are three consecutive years of La Niña which affects temperature and precipitation patterns, exacerbating drought and flooding.

    The WMO is indicating a 75% chance that La Niña will persist during December-February 2022/2023 and 60% chance during January-March 2023.

    T&T Met Service Meteorologist Gary Benjamin says this translates to more rainfall than usual in the first two months of the dry season.

    According to the WMO, this is only the third time since 1950 that there has been a triple-dip La Niña.

    It says La Niña is a large-scale cooling of ocean surface temperatures, coupled with changes in the tropical atmospheric circulation, namely winds, pressure and rainfall.
