The probability of thunderstorm activity has now decreased to a medium chance. This will further decrease to a low chance as conditions improve. Impacts from the activity over the past 24 hours should improve gradually as the afternoon progresses. Although cloudy conditions may continue to persist into the evening, impactful rainfall and winds are not expected. Settled atmospheric conditions are expected by late evening/nighttime.” according to the Trinidad and Tobago Meteorological Service.

The color of the alert indicates the severity of the event and the probability of the event occurring. Currently, the alert level is at Green, as the discontinuation was issued but the certainty is possible, meaning there is still a remote possibility of moderate impacts associated with heavy showers and thunderstorms like gusty winds and flooding.

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.
