Update May 20, 2020: 

The Trinidad and Tobago Meteorological Service said the first tropical wave for the 2020 rainy season has mostly passed after it was initially forecast to pass over Trinidad and Tobago from around midnight on Wednesday.

In an update shared Wednesday afternoon, the Met Office said the axis of the wave has passed, but there may still be some showery activity toward the evening time.

"The Tropical wave axis has passed, but the tropical wave axis is aligned in such a way that most of the rainfall is northeast and east of T&T."

"We can still expect some showery activity later this evening over both Trinidad and Tobago with cloudiness and some showers spreading over Tobago first, but intense weather is not forecasted.

The Met Office shared satellite imagery showing the main area of high rainfall activity which mainly affected Barbados at the time.

The Met Office initially advised that the showers would occur sometime after midnight on Wednesday, with cloud cover and showers, but said the atmospheric features and parameters were not expected to be supportive for thunderstorm development, so thunderstorm activity was unlikely.

The Met Office has forecast above normal rainfall activity for the months June and July, and is urging those in flood-prone areas to prepare for the possibility of flash and riverine flooding during the rainy season.

The public is urged to follow the Met Office via its official social media channels for updates. 


Original story: 

It appears that rainy conditions may start early this year, as the Trinidad and Tobago Meteorological Service announced the approach of a Tropical Wave, the first for the season. 

"The first tropical wave of the season is set to affect our weather, mainly overnight tonight. Here is a breakdown of what to expect."

The Met Office said in an update Tuesday morning the Tropical Wave is expected to bring periodic cloud-cover and showers, especially after midnight on May 20, 2020. 

The Met Office said atmospheric features and parameters are not expected to be supportive for thunderstorm development at this time, so thunderstorm activity is unlikely.

The Met Office warned that isolated street flooding is possible and gusty winds may also occur.

"Tropical waves are one of our main rainfall producers, however, you shouldn't expect hours of widespread heavy rainfall and flooding for each one. The "intensity" of these waves are related to the atmospheric features and parameters around it, at the time of passage. Some waves can produce flooding and others can pass without any rainfall."

Here's a look at today's weather: 

Generally hot and sunny with a low to medium chance of a few partly cloudy spells and showers over few areas. 

Tonight will be partly cloudy at times with isolated showers. 

The public is also cautioned that Saharan Dust is currently present in the atmosphere. Sensitive persons are advised to take the necessary precautions. 



Seas are moderate with waves up to 1.5 metres in open waters and near calm in sheltered areas.
