The Met Office is urging members of the public to brace for more rain over sections of the island.
According to recent forecasts for Jamaica, it will remain partly cloudy especially in the southern side of the island.
Initial forecasts show scattered showers in just under an hour.
Earlier, the Meteorological Service had downgraded the Flash Flood Warning to a Flash Flood Watch for low-lying and flood-prone areas.
Areas of interest include St. Mary, Portland, St. Thomas, Kingston & St. Andrew, St. Catherine, Clarendon and Manchester.
The MET Office had noted that a Trough across Jamaica continues to generate unstable weather conditions across the island and the central Caribbean.
Observational Data and satellite imagery also indicate that sections of central and western parishes will experience light to moderate rainfall and periods of thunderstorms this afternoon.
The forecast is for periods of moderate rainfall and thunderstorms to continue across the island, especially across southern and northeastern parishes tonight.
Additionally, the MET Office has warned that, due to the extended period of rainfall, and high ground saturation, landslides are likely.
A FLASH FLOOD WATCH means flooding is possible.
Residents in low-lying areas are advised to take precautionary measures.
The Met Office is urging members of the public to keep informed by listening to further news releases and be ready for quick action if flooding is observed or if a warning is issued.
