Trinidad and Tobago: Trinidad and Tobago Meteorological Service announced the Flood Alert for the country and the Orange level in effect.  

  • Riverine Flood Alert #1 – Orange Level in effect!
  • Issuance time (local time)Thu, Oct 27, 2022 7:57 PM

River levels are currently near threshold values in some parts, especially along the Caroni River and South Oropouche basin, with flooding ongoing in some areas along these rivers. Expected rainfall overnight can increase the volume of already overwhelmed water courses, and overspilling of banks is expected.

Instructions:

Monitor weather conditions and river levels before venturing out. Avoid areas with flood waters. Monitor updates from official sources and plan safety measures, including emergency supplies of food and water.

Follow the instructions of government officials.

Continuous rain periods, with scattered moderate to heavy showers and thunderstorms (mainly NE areas and Tobago last 2 hours) are affecting Trinidad and Tobago. Some thunderstorms with heavier showers recently formed near and east of Grenada, Grenadines… they are also popping up in the SE Caribbean Sea (I will share a satellite loop next post to show how much thunderstorms are spreading since around sunset.) A low to mid-level trough is around Trinidad to the Orinoco River basin.

Further east, the western portion of a ENE to WSW oriented tropical wave, is already north of Guyana near 54/55W… this new energy will become enhanced as the SE Caribbean, Trinidad and NE Venezuela region comes under favorable upper conditions. Recent satellite analysis shows a upper high pressure with light wind shear and outflowing winds has set up in that area from afternoon.

3rd pic: Analysis of steering wind flow at low to mid levels shows weak steering coming with the Tropical wave east of Trinidad and Windwards. Satellite and station reports show high moisture also.

The combination of these factors will lead to the further growth and spread of scattered moderate to heavy showers, long periods of rain, and thunderstorms over the T&T, Grenada, Grenadines which will be moving gradually slower. Risk of significant flash flood, river flood and landslide events is elevated in those areas. Some of these heavy showers will affect the St Vincent, Barbados, St. Lucia area. Risk of flash flood lower there. Please monitor your met offices for alerts if things change quickly.
