The Adverse Weather Alert

As we’ve been monitoring, the axis of Tropical Wave 15 was forecast to move across T&T with little overall activity. However, this Tropical Wave has been interacting with the Intertropical Convergence Zone and with favorable upper-level conditions, triggered inclement weather mainly for Trinidad, with now activity approaching Tobago. This was not a well forecast inclement weather event.

Weather conditions are forecast to remain deteriorated this afternoon as the axis of the wave moves west. Because of this, the Trinidad and Tobago Meteorological Service issued an Adverse Weather Alert Yellow Level on Saturday morning at 7:15 AM

This alert began at 7:15 AM Saturday 27th June 2020 and now continue through 2:00 PM Saturday 27th June 2020.
