The rainy season has officially started.

The Trinidad and Tobago Meteorological Service has officially declared the start of the 2015 Rainy Season based on the assessment of the most recent rainfall patterns and climatic conditions.

According to the Met Office, the showery activity being experienced over Trinidad and Tobago is associated with the passage of a Tropical Wave over the Southern Caribbean.

Rainfall activity as a result of the passage of a Tropical Wave or the influence of the Inter-Tropical Convergence Zone (ITCZ), whichever is first, heralds the start of the Rainy Season each year.

A release issued by the Authority stated that preliminary analysis indicated that for June to December large parts of Trinidad were likely to be wetter than usual with north Trinidad likely to be the wettest area.

Tobago, south-western Trinidad and isolated parts of north-eastern and north-western Trinidad would have increased chances for drier than usual conditions.

It went on to advise that according to the Atlantic Basin Seasonal Hurricane Forecast for 2015 issued by Colorado State University, this season is forecast to be one of the least active seasons since the middle of the 20th century, with the expected formation of 7 named storms, 3 hurricanes and 1 major hurricane (Categories 3 and above).
