Weather: Mid-upper trough has weakened and moved west over the central Caribbean Sea/Central Venezuela whilst an upper equatorial ridge has built over NE South America and the islands. This is helping pockets of moderate to heavy thunderstorms, mainly over Guianas and offshore waters.
A surface to mid-level trough is over Guyana/Suriname stretching north. This will cause scattered moderate to heavy showers and thunderstorms in coastal Guianas then will bring an increase in showers and isolated thunderstorms at first to Trinidad, Tobago, Grenada and Grenadines, from early Saturday morning then late Saturday to Sunday afternoon this will also spread to the Windwards.
Some showers will spread to the Leewards as the surface trough moisture is drawn NW due to a weakening in the high pressure. Best chance for thunderstorms with intermittent heavier showers in southern islands. Trinidad and Tobago can expect to have renewed risk of flash flooding and mudslides.
By late Sunday to early Monday drier air moves in to the northern islands to the north and central Windwards. During this time models show occasional rainfall chances continue on Trinidad through Monday afternoon.
Some heavy rainfall affected the Windwards from St. Lucia to parts of NE Trinidad and Tobago. Today there continues to be widespread areas of rain with occasional moderate to heavy showers mainly east of Trinidad. Scattered moderate to heavy thunderstorms are also impacting coastal Guyana.
Next few days thru the weekend, deep layered troughing will maintain wet conditions at the same time, a well-defined surface to low-level trough passes with a few others already affecting Guyana and east of the region. In the Windward Islands, Trinidad and Tobago and Guyana, expect occasional periods of rain with scattered moderate to heavy showers.
Better chances for heavy rainfall in southern areas. Trinidad and Tobago especially can expect times where heavy rainfall worsens flash, river flooding and landslides. In the Windwards, an elevated risk of flash flooding and landslide events will remain during heavier rainfall periods.
In the Leewards, some light to few moderate showers will occur from time to time.
