The Met Service has extended its Yellow Level Adverse Weather Alert.

Initially scheduled to end at 6PM today (Sunday), it will now continue until 6PM tomorrow (Monday).

The TTMS says there is a high (80%) chance of periods of intermittent rainfall of varying intensities and isolated thunderstorms over Trinidad, especially across southern and central areas, where recent rainfall has already saturated some locations.

Tobago has a medium (60%) chance of isolated heavy showers or thunderstorms, but as higher concentrations of Saharan dust are expected there, widespread rainfall activity is forecast to be limited.

Despite the forecast rainfall, both islands will experience significant Saharan dust levels, which may reduce visibility and air quality at times.

The ITCZ is gradually migrating northward and is expected to add to the ongoing unsettled conditions, enhancing rainfall and thunderstorm activity overnight into tomorrow.

The TTMS warns there is a heightened risk of landslides/landslips in vulnerable areas.

Additional impacts include street or flash flooding, localized ponding, gusty winds in the vicinity of heavy downpours which can also lead to agitated seas.
