“After continued rainfall activity, the Manuel Congo River and the Caroni River near the Tumpuna and El Carmen areas have all reached critical threshold levels (based on official data) and may soon overflow their banks as water levels continue in an upward trajectory. While weather conditions have settled over Trinidad currently, further rainfall activity will likely continue over the next 24 hours which will result in further elevation of these river levels. As a result, there continues to be a severe risk to public safety, livelihood and property in communities surrounding these rivers. Other major rivers, including the North and South Oropouche, are rising at relatively lower rates but are also being monitored closely,” according to the Trinidad and Tobago Meteorological Service. This “alert” status takes into account the possibility of the event occurring. This riverine flood event is likely.
