Trinidad and Tobago will be under an Adverse Weather Alert (Yellow Level) from 11:00 AM Tuesday through 5:00 PM Wednesday due to forecast inclement weather.

Periodic rainfall and isolated to scattered thunderstorms are forecast across Trinidad and Tobago over the next 48 hours, accompanying the passage of a tropical wave that is also being monitored for tropical cyclone formation.

According to the Trinidad and Tobago Meteorological Service (TTMS), rainfall and thunderstorm activity is forecast to bring the threat of gusty winds, street flooding, and isolated flash flooding. The TTMS notes that the worst of the weather is forecast across Trinidad and, to a lesser extent Tobago.

With this yellow-level alert, moderate impacts are likely. These include the potential for possible injuries, where behavioral changes are required to ensure safety, minor property damage, with income-earning temporarily disrupted, and a couple of communities are affected.

The Met Office is advising the public to monitor weather conditions and official updates. Though the alert ends at 5:00 PM on Wednesday, rainfall is forecast to continue through the end of the month as additional tropical waves are forecast to traverse the region.

NHC: Low Chance of Development

According to the National Hurricane Center (NHC), this tropical wave, located approximately 1,350 kilometers east of Trinidad and Tobago, is producing disorganized showers and a few thunderstorms.

In their 2:00 PM Tropical Weather Outlook on Monday, the NHC stated, “Although shower activity has diminished some this afternoon, recent satellite-derived surface wind data indicate that the wave has become better defined since yesterday. Some additional development of this disturbance will be possible during the next couple of days before upper-level winds become less conducive for further organization by Thursday.”

The system is expected to move westward to west-northwestward at 15 to 20 miles per hour (24 to 32 kilometres per hour). The NHC gives this system a low chance of tropical cyclone formation over the next 48 hours and five days, at 30 per cent.
