“There is a high (70%) chance that the passage of a tropical wave will result in heavy showers/thunderstorms. These conditions are expected to occur intermittently over the period, starting with southern areas of Trinidad. These thunderstorms can produce intense rainfall of over 25mm. Street and/or flash flooding are possible in areas so prone, causing minor traffic disruptions. Electrical discharges are also likely. The threat of gusty winds will also be present. These wind gusts may be brief, but are capable of breaking tree branches, displacing unsecured roofs and loose outdoor objects, and can even topple over unhealthy trees.” 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.
