“An intense area of instability and moisture is ahead of the axis of an approaching tropical wave. This will affect the islands with cloudy skies, prolonged periods of rainfall, and occasional thunderstorms which can result in rainfall accumulation in excess of 25mm and gusty winds in excess of 55 km/h. Possible impacts include street flooding which can cause minor traffic disruptions. Ponding is possible in low-lying areas. Loose items can become displaced by strong winds. Electrical discharges are possible during thunderstorms. Note as well, low-lying coastal areas may have slower runoff during high tide due to the occurrence of Spring Tides,” 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 Yellow. This means that the hazards are likely, but the severity of 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, and flash flooding 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 be alert for cloud-to-ground lightning activity and not venture into floodwaters, secure loose objects outdoors as well as monitor weather conditions and updates from official sources.
Small craft operators should be on the alert for above-normal or choppy sea conditions in strong winds.
