Summary:

Moderate to high rainfall amounts are expected on four of the fifteen days.

Four wet days with rainfall amounts ranging between 10.0 mm and 40.0 mm are expected on the 21st-24th of September, while eleven relatively wet days with rainfall amounts ranging between 1.0 mm and 9.0 mm are expected on the 25th-5th of September/October.

Trinidad:

Four wet days with rainfall amounts ranging between 10.0 mm and 40.0 mm are expected on the 21st-24th of September, while eleven relatively wet days with rainfall amounts ranging between 1.0 mm and 9.0 mm are expected on the 25th-5th of September/October. The daily rainfall totals are forecast to range between 1.0 mm to 40.0 mm across different farmlands, with fifteen-day rainfall totals ranging between 60.0 mm and 100.0 mm. The impactful rainfall events will mostly occur across the northeastern, southeastern, southwestern and northwestern parts of Trinidad. There is a high (80%) probability that flash and riverine flooding will occur during/after heavy rainfall events.

Tobago:

Similar to Trinidad, Tobago will experience four wet days with rainfall amounts ranging between 10.0 mm and 40.0 mm are expected on the 21st-24th of September, while eleven relatively wet days with rainfall amounts ranging between 1.0 mm and 9.0 mm are expected on the 25th-5th September/October.  The daily rainfall totals are forecast to range between 1.0 mm to 40.0 mm across different farmlands across the island, with fifteen-day rainfall totals averaging around 100.0 mm.

Temperatures & Winds:

The maximum temperatures are expected to remain warm, with temperatures ranging between 29.0oC to 33.0oC throughout the period. However, temperatures are expected to have a real-feel or feels-like between 32.0oC to 45.0oC on most days. The minimum temperatures will range between 23.0oC to 25.0oC during most nights/early mornings, dropping lower in rural areas and valleys.

In general, mostly weak easterly to south-easterly winds of an average speed of 10-20 km/h are expected, however gusts can reach speeds of up to 50-70 km/h especially during heavy showers. Moderate to high rainfall totals, mostly low wind speeds, warm to very warm days and warm feels-like temperatures will sustain average evapotranspiration rates in crops ranging between 1.0 to 8.0 millimeters per day.

Moisture levels:

Over the fifteen-day period across Trinidad and Tobago, moisture levels are expected to be moderate to high, with average daytime relative humidity values in the lower-60s to lower-90s, in terms of percentage.
