At 12:00 PM, usual afternoon showers and thunderstorms developed across western Trinidad, with a few isolated showers elsewhere. These showers began triggering street flooding across Northwestern Trinidad.

These showers intensified along the coastal areas of Northwestern Trinidad and moved onshore, bringing mainly a street and flash flooding threat due to the heavy rainfall through 2:00 PM.

Winds are generally light, below 15 KM/H from the southeast, so this activity is mainly moving towards the north to northwest.

Heavy rainfall rates have produced street flooding across the East-West Corridor from Aranguez into Port of Spain and further west into Diego Martin and Maraval. Flooding was also reported along Saddle Road in Hololo as well as along Eastbound lanes of the Beetham Highway.

As the afternoon progressed, flooding was also reported in St. Augustine and Valsayn.

By the late afternoon, conditions are forecast to become more settled across Trinidad, with partly cloudy skies just in time for this evening’s match at the Queen’s Park Oval.

Showers and thunderstorms during the late morning through the afternoon, mainly across Western Trinidad are normal during the rainy season, triggering brief street and flash flooding, at times accompanied by gusty winds. There are no adverse weather alerts in effect, as this activity is normal for this time of year.

Sea breeze convergence occurs when winds from the Gulf of Paria moves onshore (westward) meets the overall trade winds (generally from the east to southeast) and converges (moves up). This aids in the development of showers and thunderstorms when moisture is present.

Day time heating also contributes to this convergence, as the hotter the atmosphere becomes, the easier (generally) it is for air to rise, triggering locally intense showers.

Similar activity is forecast on Tuesday, with a tropical wave approaching the region on Wednesday, bringing the threat of street and flash flooding to parts of Trinidad yet again.
