The Met Office has issued a Riverine Flood Alert, raising the level two place up from Green to Orange.
Orange is the second highest level, just below red.
Orange represents a "high-risk" of flooding.
The Met Office says river levels are currently near threshold values in some parts, especially along the Caroni basin and minor flooding has commenced in certain regions as well.
Rainfall is still in the forecast and the river levels are gradually rising which can become exacerbated around high tide times.
Therefore, a high risk to public safety, livelihoods and property exists in these areas.
Persons residing, traversing or working in flood prone areas, especially along the Caroni River Basin are urged to be extra vigilant and to take the necessary actions to preserve life and property.
Be alert for rising river levels and possible over-spill.
Do not take unnecessary risks.
Avoid intentionally walking or driving through flood waters.
