Adverse Weather Alert Extended Until 6 PM Monday For T&T

Key Messages:
— A surface to low-level trough is moving across Trinidad and Tobago, with a favorable atmospheric environment. However, strong wind shear is keeping much of the activity brief and mainly east of Trinidad and Tobago. Showers and thunderstorms are still forecast to affect the country through Monday. Note that higher, overall rainfall accumulations are forecast to remain across southern and eastern areas of the country, with localized high totals along western Trinidad.
— Main impacts include gusty winds up to 45 KM/H, with winds in excess of 55 KM/H possible, and street or flash flooding across Trinidad and Tobago. Increased sustained winds across the country, particularly ahead of and during thunderstorms and heavy showers are also possible. These gusty winds may cause scattered areas of power dips/outages, downed trees, and localized wind damage. The highest flood threat exists along the eastern half of Trinidad as smaller watercourses are already near or at threshold levels.
— Frequent lightning may accompany thunderstorms. Funnel clouds and waterspouts are unlikely. Seas are forecast to remain agitated.
– The alert remains effective from 3:30 AM Sunday through 6:00 PM Monday for both Trinidad and Tobago.

“Although a few settled periods can be experienced this evening, there is still the high (70%) chance of heavy downpours and thunderstorms. Elevated river levels and saturated soils will increase the likelihood of localized ponding and street flooding. Smaller watercourses can become overwhelmed in heavy downpours. Gusts in excess of 55km/h can be expected near heavy downpours and can displace loose outdoor objects and unsecured roofs. Landslides/landslips are also likely in areas so prone.” according to the Trinidad and Tobago Meteorological Service. This “alert” status takes into account the possibility of the event occurring. This adverse weather event is likely.
