The Trinidad and Tobago Meteorological Service has issued an Adverse Weather Alert Yellow Level on Wednesday afternoon at 4:38 PM, which will go into effect at 5:00 AM Thursday 1st October 2020, and will remain in effect through 8:00 AM Friday 2nd October 2020, though this may be extended as severe weather is possible into the weekend.

Trinidad and Tobago is not under any tropical storm watch or warning at this time.

The Intertropical Convergence Zone (ITCZ) is expected to become very active over Trinidad and Tobago from early morning tomorrow, Thursday 1st October 2020. This abundance of moisture and favourable upper level conditions, in addition to the passage of a tropical wave, will create very unstable conditions over our area. As such, periods of showers and rain are likely in most areas and occasional thunderstorm activity can be expected as well. Accompanying this shower activity will be a surge of winds in the low levels which will promote very gusty conditions, particularly during heavy showers and thunderstorms.” 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.
