4:00PM Monday 4th February 2019: Low Level Convergence Bring Cloudy Skies, Isolated Showers This Evening & Overnight, Interrupting Mostly Settled Conditions.
An area of low level convergence, producing isolated to scattered showers and cloudy periods are approaching mainly Trinidad from the East. These conditions are a result from surface to low level confluence on the southern periphery of the Atlantic high-pressure system, combined with a minimal increase in low-level moisture.
While mostly sunny to partly cloudy skies will likely persist through sunset, some isolated showers are possible through the late evening period and overnight, persisting into the early morning period. Note that these showers will be fairly brief, and light to moderate in nature.
A similar pattern is expected to remain throughout the week, remaining mostly sunny through the day, with building clouds by the afternoon and low chances of isolated showers by the late afternoon, favoring Southwestern and Eastern Trinidad.
With increased, albeit minimal, low-level moisture, overnight low temperatures will likely remain above 21-22°C, with high temperatures at 31-32°C expected on Tuesday.
Trinidad and Tobago is now under a drought warning, meaning that Trinidad and Tobago has received much less rainfall than average over the last 2 months. These isolated showers will not provide any noticeable relief to the overall drought conditions.
Rainfall will occur throughout the dry season, the same way we see sunny skies during the wet season. During the dry season, we expect to see overall (i.e. over the course of the first half of the year) drier than usual conditions the same way wetter than usual conditions will occur during the wet season (second half of the year).
