Official Statement from the Trinidad and Tobago Meteorological Office: 2013 Rainy Season is here


The arrival of the first rain-producing Tropical Wave for 2013 last night (Sunday, 19 May, 2013) heralds the beginning of the 2013 rainy season. Given our weather-related history it has occurred just on time. This signals for Trinidad and Tobago a consistent intervention of Tropical Waves and the Inter-Tropical Convergence Zone (ITCZ) into our weather over the next seven (7) months. In essence, expect to see more episodes of rain in the coming months than the daily bouts of sunshine we have been experiencing.


Preliminary analysis indicates this year's rainy season should be very productive - more so than is usual. Over the years, the months of June, July and August have been coincident with the period our country has received the most amount of rainfall with July in particular standing above the others. There is no reason to believe that the 2013 rainy season will play out otherwise.


At present, the quick succession of Tropical Waves is not firmly established. So, there may be a reprieve following the passage of this wave. The stay, however, will be short-lived especially with the expected start of the Tropical Atlantic Hurricane Season on 01 June, 2013. This year the season is forecast to be a very active one with the formation of 18 named Storms, 9 Hurricanes and 4 Major Hurricanes (Categories 3 and above). Historically, the averages for named Storms, Hurricanes and Major Hurricanes are 12, 7 and 2 respectively.


Therefore, the overall picture weather-wise calls for a prepared public.


The Trinidad and Tobago Meteorological Service will continue to do its part in terms of early warning. In this regard, pay attention to the daily weather forecasts and updates. These are released 6:00am, 10:00am, 3:00pm and 6:00pm. Each forecast updates the previous. 


For cases of expected moderate to severe weather impacts, Information or Severe Weather Bulletins will be released accordingly.


Riverine Flood Bulletins will be issued whenever river levels, given current and expected rainfall, threaten to defeat maximum carrying capacities.


Finally, Tropical Storm/Hurricane Watch/Warnings will be issued whenever the effects of these systems are expected to be felt by this country in 36/48 hours.
