Trinidad and Tobago: Disruptions due to flooding ongoing across parts of Trinidad as of early Nov. 24
Disruptions due to flooding ongoing across Trinidad, Trinidad and Tobago, as of early Nov. 24. Further adverse weather forecast.
Event
Disruptions due to flooding are ongoing across parts of Trinidad as of early Nov. 24. Heavy rainfall since Nov. 17 has resulted in flooding, landslides, and fallen trees across the country. Eastern Trinidad is the worst affected by flooding. Manzanilla Mayaro Road partially collapsed Nov. 23; authorities have closed the road until structural assessment is complete.
The Trinidad and Tobago Meteorological Service has issued a yellow (lowest level on a three-tier scale) adverse weather alert across the country through at least Nov. 24; periods of heavy rain and thunderstorms are forecast, especially from late morning to early afternoon Nov. 24. Authorities have warned that the land remains very saturated, increasing the risk of flash flooding, localized ponding, and landslides. Gusty winds in excess of 55 kph (34 mph) are possible, especially in the vicinity of heavy showers and thunderstorms. Several rivers are at dangerously high levels, including the North Oropouche River and the Caroni River, which authorities have reported is at 93 percent capacity at El Carmen. Further downpours will likely trigger additional flooding in the coming days, as well as hamper ongoing recovery efforts.
Hazardous Conditions
Sustained heavy rainfall could trigger additional flooding in low-lying communities near rivers, streams, and creeks. Urban flooding is also possible in developed areas with easily overwhelmed stormwater drainage systems. Sites located downstream from large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall. Landslides are possible in hilly or mountainous areas, especially where the soil has become saturated by heavy rainfall.
Authorities could issue mandatory evacuation orders for flood-prone communities over the coming days. Disruptions to electricity and telecommunications services are possible where significant flooding or landslides impact utility networks.
Transport
Floodwaters and debris flows could render bridges or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters.
Localized business disruptions are likely in low-lying areas; some businesses might not operate at full capacity because of flood damage to facilities, possible evacuations, and some employees' inability to reach work sites.
Advice
Monitor local media for weather updates and related advisories. Confirm all transport reservations and business appointments before travel. Make allowances for localized travel delays and potential supply chain disruptions where flooding has been forecast. Do not drive on flooded roads. Charge battery-powered devices in the case of prolonged electricity outages.
