Due to the passage of a tropical wave, adverse weather is forecast to begin after midnight across Trinidad and Tobago. Scattered showers and thunderstorms are possible across both islands.
Trinidad and Tobago is NOT under any tropical storm threat, watch or warning.
This may result in street/flash flooding, particularly in flood-prone areas, or areas that receive heavy and/or prolonged rainfall. In addition, gusty winds may occur near or during heavy showers or thunderstorms. These gusty winds may down trees and/or utility poles. Landslides are also possible in landslide-prone areas.
Because of the impending adverse weather, the Trinidad and Tobago Meteorological Service has issued an Adverse Weather Alert at 3:00 PM Saturday 1st June 2019.
Information from the Trinidad and Tobago Meteorological Service concerning the Adverse Weather Alert for June 2nd 2019.
This “alert” status takes into account the possibility of the event occurring. This adverse weather event is likely. However, showers and thunderstorms are forecast to decrease in coverage and intensity as the day progresses.
The color of the watch indicates the severity of the event and the probability of the event occurring. Currently, the alert level is at Yellow. This means that the hazard is possible to be aware of the impacts of Street/Flash Flooding and Gusty Winds in your area. Areas prone to landslides should also be aware of the hazard and impacts.
The second tropical wave of the 2019 Atlantic Hurricane Season is located in the Central Atlantic Ocean in the latest tropical update. The axis of this wave is located at 55W, with a surge of moisture trailing the wave axis. In addition, a surge of trade winds and Saharan Dust is forecast to follow this wave, bringing moderate concentrations of Saharan Dust across Trinidad and Tobago over next week.
Based on the latest model guidance, the axis of this wave is forecast to move across Trinidad and Tobago Sunday, with active weather occurring on Sunday into Monday.
A frequent complaint is the forecast is wrong because I didn’t experience any rainfall. Scattered showers means that you, individually, may experience some showers intermittently throughout the day and there is a higher chance for this activity than isolated activity. Generally, because of winds associated with weak tropical waves, showers and thunderstorms tend to follow a west-northwest track, generally missing areas across Southwestern Trinidad and even Northwestern Trinidad – though activity due to local climatic effects such as daytime heating may trigger shower and thunderstorm development across these areas.
This wave is not forecast to produce widespread severe weather, nor is it forecast to produce widespread heavy rainfall. However, locally heavy rainfall is possible in heavy showers and/or thunderstorms, as well as gusty winds. Generally, 10-20 millimeters are forecast across Trinidad and Tobago, with isolated areas receiving 30-40 millimeters over the 48 hour period. There is the concern for street and flash flooding, as well as gusty winds in heavy showers and thunderstorms, particularly on Sunday.
A full update on the tropics, the start of the 2019 Atlantic Hurricane Season and Invest 91L will be posted later this evening.
