The La Niña phenomenon, which has led to drought conditions in some parts of the world and flood conditions in others, including Trinidad and Tobago, is likely to continue into early 2023. So said the World Meteorological Organization (WMO) in a Press Release issued this morning (Wednesday 30th November 2022).
”The unusually stubborn and protracted La Niña event is likely to last until the end of the Northern Hemisphere Winter/Southern Hemisphere Summer,” the Press Release stated. “The first ’triple-dip’ La Niña (three consecutive years) of the 21st century will continue to affect temperature and precipitation patterns and exacerbate drought and flooding in different parts of the world,” it continued. In its own Press Release on Wednesday, the Ministry of Public Utilities explains that the La Niña, a natural weather-forming phenomenon, which occurs every few years, refers to the large-scale cooling of ocean surface temperatures in the Central and Eastern equatorial Pacific Ocean, coupled with changes in the tropical atmospheric circulation, namely winds, pressure and rainfall. It usually has the opposite impacts on weather and climate as El Niño. For the Caribbean region, the Ministry notes that this has “led to a Wet Season characterized by above-normal rainfall which is likely to continue into what is usually the Dry Season. In fact, the Caribbean Institute for Meteorology and Hydrology (CIMH) at their recently concluded Caribbean Climate Outlook Forum (CariCOF), indicated that the probability of the region experiencing above-normal rainfall into January of next year is 45%, while from February to April, there will be a 50% probability of above-normal rainfall in the Southern Caribbean.” “This trend towards above-normal rainfall has already led to record-breaking levels of precipitation in Trinidad and Tobago, with this November being the wettest on record since 1946,” the Ministry said. “The Trinidad and Tobago Meteorological Service (TTMS) will continue to monitor the weather conditions in and around Trinidad and Tobago for the purpose of providing timely, accurate and relevant meteorological information and advice to the public,” the Ministry added. The TTMS is urging the general public to pay close attention to alerts and updates issued via their social media: Trinidad and Tobago Meteorological Service, or their website: www.metoffice.gov.tt.
