The Adverse Weather Alert
The Trinidad and Tobago Meteorological Service has issued an Adverse Weather Alert (Yellow Level) on Friday afternoon at 2:45 PM. This alert will go into effect from 11:00 PM Friday 1st October 2021 through 6:00 PM Saturday 2nd October 2021 for Trinidad and Tobago and surrounding marine areas.
Trinidad and Tobago is not under any tropical storm watch or warning at this time.
“Due to a surge of relatively strong winds in the lower levels of the atmosphere, there is a high potential (70%) for gusty winds in excess of 55km/hr to accompany intermittent showers and isolated thunderstorms. Activity is expected to initially affect Tobago and gradually spread across Trinidad. While showery activity may be experienced by early night, more impactful activity is expected as the night progresses. Street flooding is likely in heavy downpours. Seas can become agitated especially in the vicinity of heavy showers/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.
The color of the alert 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 likely, but the severity of impacts is moderate for this particular alert. You should be aware of the hazards in your area associated with gusty winds in excess of 55 KM/H, street, and flash flooding as well as landslides.
