Tropical-storm-force wind gusts moved across Trinidad and Tobago on July 8th, 2021, associated with the passage of Tropical Wave 17. Approximately 111 reports of adverse weather impacts were reported across the country, with 97 reports of wind damage, eight reports of flooding, and six landslides with at least 75 power outages. Fallen trees knocked out Digicel’s network to Tobago, with wind damage and a landslide reported on the island.
What caused the gusty winds?
A low-level jet, or an area of strong winds at low levels of the atmosphere, was present across the Windward Islands on Thursday. These stronger winds can make it down to the surface in heavy showers and thunderstorms, particularly in dissipating activity.
When these strong winds make it to the surface, the winds can hit the ground in a concentrated area and radiate outward like a ripple in a pond. This activity is known as a downburst and causes substantial wind damage across a fairly large area.
For this inclement weather event, separate thunderstorms caused damage across the northeastern and north-central Trinidad, central Trinidad, southwestern Trinidad, and Tobago.
Which areas were affected?
Of the 14 municipal corporations across Trinidad, 11 had inclement weather reports by Trinidad and Tobago Weather Center’s count. Additionally, Tobago also had two inclement weather reports, not including their telecommunications outage. The hardest-hit municipal corporations were Tunapuna/Piarco, Sangre Grande, Arima and San Juan/Lavantille, as well as Couva/Tabaquite/Talparo.
Tunapuna/Piarco Regional Corporation (TPRC)
The Tunapuna/Piarco Regional Corporation was arguably the hardest hit, with 15 reports of fallen trees or poles, 15 reports of wind damage, and one landslide.
Within this area, wind gusts up to 70 KM/H were recorded at Piarco. Fallen trees were widely reported across the East-West Corridor, from D’Abadie, to well into the Northern Range in Lopinot and as south as Valsayn South and Bamboo #2. Strong winds caused power outages and sparking power lines across this area.
The Eastern Main Road became temporarily impassable as a large tree fell across the roadway in Tacarigua. A tree also fell onto a vehicle at Century Drive, Macoya Industrial Estate. A landslide was also reported along Riverside Road, Maracas St. Joseph.
TPRC Chairman Kwasi Robinson told the Trinidad Express in a telephone interview yesterday that over two dozen uprooted trees/broken branches in the region, which stretches from Blanchisseuse in the northeast, Wallerfield in the East, Maracas in the west, and Caroni in the central.
“It’s a fairly large area, and the terrain creates a lot of landslips. We had a few small landslips, but mostly trees were uprooted. We cut most of them on Thursday night, and currently, we continue to do assessments.”
Sangre Grande Regional Corporation (SGRC)
With 15 adverse weather reports in this area, the SGRC was the second-hardest hit municipal corporation. There were three reports of fallen trees or poles, one of which fell on a vehicle in Cumana, 11 reports of roof damage.
According to Councillor for Toco/Fishing Pond Terry Rondon, there was, unfortunately, one collapsed structure, also in Toco.
“We had damage in Valencia with roofs blown off. At least one house had a tree fall on it. A tree fell in Cumana and damaged a car. All in all, thank God there was no loss of life. Today (Friday), we have kinder weather. Although it was forecast we would have had rain, there was not much rain,” he said in an interview with Trinidad Express.
