“A series of low-level troughs bringing Equatorial moisture into our area is presently affecting Trinidad and Tobago. While soils are near saturation, a peak in activity is expected from mid-morning to early afternoon,” according to the Met Office.
This “alert” status takes into account the possibility of the event occurring. This adverse weather event is likely with the following impacts, according to the TTMS:
- Periods of rain and/or showers of varying intensities are expected, with a medium to high (40 – 70%) chance of heavy showers and/or thunderstorms that can produce intense rainfall in excess of 50mm.
- Street/flash flooding and localized ponding are also likely in heavy downpours.
- Landslides/landslips are also possible in susceptible areas.
- In the event of heavy showers/thunderstorms, gusty winds in excess of 55 km/h as well as agitated seas in sheltered may be experienced.
The color of the alert indicates the severity of the event and the probability of the event occurring. Currently, the alert level is Yellow. This means that the hazards are likely, and the severity of the impacts is moderate for this particular alert. You should be aware of the hazards in your area associated mainly with gusty winds in excess of 55 KM/H, street, flash, and riverine flooding, landslides, as well as frequent lightning.
For a moderate Adverse Weather Alert, there is the potential for possible injuries, where behavioral changes are required to ensure safety. There may be minor damage to property, with income-earning temporarily disrupted and a couple of communities affected.
The Met Office is advising the public to monitor weather conditions and updates from official sources and not wade or drive through flood waters.
