The Met Service says moderate chances exist for mostly near-normal rainfall totals during the period April to June.

Near-normal means anywhere from 75% to 125% of the average rainfall amounts are possible.

However, the TTMS adds that some small pockets may experience above-normal rainfall, with enhanced chances for an above-average number of extremely wet days.

These forecasts were contained in the TTMS’ Rainfall and Temperature Outlook for April to June 2024.

Key Messages:

• Moderate chances exist for mostly near-normal rainfall totals during April to June (AMJ) over Trinidad and Tobago
• Near-normal means that a range of 75% to 125% of the average rainfall amounts are possible
• Some small pockets may experience above-normal rainfall
• Enhanced chances for an above average number of extremely wet days (> 25.0 mm)
• May has a higher chance for above-normal rainfall
• AMJ period rainfall totals with the highest chance of occurring range between 277.0-728.0 mm in Trinidad and between 234.0-482.0 mm in Tobago

Likely Impacts:

• Mostly near average rainfall totals are expected during April to June with high chances for above-normal number of wet days and high chances for flooding to occur in May and June
• An increase in surface water ponding in areas can promote mosquito breeding. This will increase the risk for higher incidences of vector-borne diseases
• Frequent rainfall events, mixed with warm and humid conditions tend to promote rapid multiplication of some agricultural pests, diseases and fungal growth
• High probability exists for high fly and mosquito populations
