Tropical Wave 05 is forecast to move across Trinidad and Tobago on June 5th 2020. Following the passage of this wave, periods of showers and thunderstorms are possible, mainly overnight Thursday through Friday afternoon, with isolated thunderstorms possible on Saturday. Locally heavy rainfall may trigger street or flash flooding. Gusty winds in excess of 60 KM/H may cause downed trees, utility poles, and lines, as well as brief power outages. The chances for landslides/landslips remain very low, as much of the heavy rainfall is forecast to favor offshore areas, as well as along Eastern halves of the islands. Live Updates for this inclement weather event have now ended.

Overnight Power Outages Not Linked To Weather
Friday 5th June 2020
According to a LoopTT report, the Corporate Communications Manager for the Trinidad and Tobago Electricity Commission (T&TEC) Annabelle Brasnell has said last night’s outage across much of Trinidad and Tobago was not due to inclement weather.
Instead, an issue of low frequency originated from the Trinidad Generation Unlimited (TGU) power plant in La Brea, according to another senior T&TEC official at 2:30 AM.
While in most areas, power was restored within 5 to 30 minutes, supply was fully restored at 4:00 AM according to T&TEC’s Corporate Communications Manager.
Additional Showers, Thunderstorms Possible Through The Afternoon
10:00 AM Friday 5th June 2020
Over the last 7 hours, Tropical Wave 05 has brought persistent rainfall with locally heavy to violent showers and isolated thunderstorms across Trinidad, lesser so Tobago.
Several areas across Trinidad recorded rainfall accumulations between 20 to 65 millimeters and isolated areas up to 70 millimeters. Given our overall dry soils and low river levels, there have been little to no reports of street or flash flooding, with river levels well within their banks. Street/Flash flooding did occur across parts of Northern Trinidad between 2:00 AM and 4:00 AM.
As the axis of this wave continues to move west, a highly upper level divergent and low-level convergence pattern remains across Trinidad and Tobago, with high atmospheric moisture present. Overall dynamics remain favorable for shower and thunderstorm development through today.
Hence, isolated to scattered showers, light to moderate rain and isolated thunderstorms are still possible throughout the day. This activity will continue to bring the threat of street flooding, gusty winds in excess of 60 KM/H, and frequent lightning (in thunderstorms). The threat of landslides and flash flooding remains lower. Maximum temperatures across Trinidad and Tobago are forecast to reach near 28-29°C due to increased cloud cover. The Adverse Weather Alert (Orange Level) remains in effect through 4:00 PM today, though isolated showers and thunderstorms are forecast overnight into Saturday.
Heavy Showers, Isolated Thunderstorms Continue to Affect Trinidad
3:00 AM Friday 5th June 2020
The axis of Tropical Wave 05 has now moved across Trinidad and Tobago. Showers and thunderstorms are already affecting the island, triggering power outages across Trinidad, street flooding across parts of Northern Trinidad, and lightning across parts of the island.
The Adverse Weather Alert (Orange Level) is now in effect through 4:00 PM today. Additional showers, thunderstorms are forecast to affect both islands as we move through the mid-morning.
Power Outages Reported Across Various Areas of Trinidad
2:35 AM Friday 5th June 2020

- Chin Chin
- La Romain
- El Dorado
- Sangre Grande
- Port of Spain
- San Fernando
- Point Fortin

In a few areas, supply was restored within 5 minutes. However, most areas continue to report no power.
Overall Rainfall Accumulations, Chances For Flooding Increased
2:20 AM Friday 5th June 2020
Based on the latest modelling (00Z Friday 5th June 2020), models are showing overall heavier rainfall accumulations across Trinidad and Tobago.
Over the next 24-48 hours, Trinidad and Tobago may see accumulations between 25-50 millimeters, with isolated totals in excess of 75 millimeters. On the upper end of model guidance, isolated totals of up to 125 millimeters are possible.
Much of these heavier rainfall accumulations are forecast to favor Southern and Eastern halves of Trinidad, as well as much of Tobago.
Because of these changes, as well as the upgrade to Orange Level for the Adverse Weather Alert, our chances for the various types of flooding has increased. The chances for street flooding is now high to very high, flash flooding is high, riverine flooding is very low to low. The possibility of gusty winds in excess of 55 KM/H remains medium to high, with the threat of frequent lightning high.
Thunderstorms Remain East of Trinidad, Approaching Tobago
12:45 AM Friday 5th June 2020
Isolated showers are moving across Trinidad and Tobago, with mostly cloudy skies. Isolated thunderstorms remain east of Trinidad and south of Tobago, gradually moving west to the west-northwest.
Based on current speed and movement, these thunderstorms may impact Eastern Trinidad and Tobago within the next 1-2 hours.
Adverse Weather Alert Level Raised To Orange
11:52 PM Thursday 4th June 2020
The Trinidad and Tobago Meteorological Service raised the alert level from Yellow to Orange in Adverse Weather Alert #2. While the certainty of the event remains likely, impacts moved from moderate to severe, according to the TTMS’ risk matrix.
This means severe weather resulting from Tropical Wave 05 could bring the loss of a single life or serious injuries where physical defenses (sandbags) are needed. There may be major losses in confined areas and income earning may be impossible for several days. Several communities may be affected, with external help needed for recovery.
Heavier Showers, Isolated Thunderstorms Developing Across Southern Trinidad
11:00 PM Thursday 4th June 2020
As forecast, much of the heavier showers and thunderstorms are still forecast to begin across Trinidad and Tobago after midnight tonight, with thunderstorm activity beginning by 2:00 AM to 3:00 AM across the islands. Until then, most areas are forecast to continue experiencing near calm conditions with increasing cloudiness, at times interrupted by the odd shower.
Presently, isolated heavier showers are developing across the southern and eastern coasts of Trinidad with much of the existing thunderstorm activity still east of T&T, along with the wave axis. These heavier showers could develop into thunderstorms. The main hazards – street flooding, gusty winds and frequent lightning (in thunderstorms).
Showers Beginning To Move Across Trinidad
8:45 PM Thursday 4th June 2020
