Guyana is facing a heightened flood threat as prolonged, above-normal rainfall is expected to impact large sections of the country through April 25, with authorities warning of widespread disruptions and potential damage.
The Civil Defence Commission (CDC), in a situation update issued Wednesday, said the advisory from the Hydrometeorological Service points to sustained rainfall with flooding risks, particularly in Regions Five, Six, Seven, Eight and Nine, which are projected to receive the highest volumes.
This comes on the heels of a Special Information Bulletin from the National Weather Watch Center, which outlined that unstable atmospheric conditions driven by a strengthening Inter-Tropical Convergence Zone (ITCZ) will trigger moderate to heavy rainfall, thunderstorms and increased water levels nationwide.
“Periods of rainfall, with the potential to cause flooding, are expected to persist across Guyana…with Regions 5, 6, 7, 8, and 9 likely to receive the highest amounts of rainfall throughout the period April 22nd to 25th, 2026,” the CDC stated.
Forecast models indicate rainfall accumulations could reach between 50mm and 75mm within 24 hours, with some locations exceeding 100mm, creating conditions for rapid water buildup, especially in low-lying and poorly drained communities.
Authorities are warning that the impacts could be far-reaching. Anticipated effects include coastal flooding, drainage overflow leading to road inundation, agricultural losses affecting crops and livestock, riverine flooding with possible community isolation, and delays across transportation networks, including airstrips and interior trails.
The Hydrometeorological Service further cautioned that residents should expect reduced visibility during intense showers, gusty winds and lightning associated with thunderstorms, as well as hazardous driving conditions.
In response, the CDC is urging citizens to take immediate precautionary measures, including avoiding flood-prone areas, clearing drains and waterways, securing critical documents and valuables, preparing sandbags, and elevating household items where necessary.
“Exercise extreme caution when driving or walking during rainfall, especially in areas affected by pooling water,” the commission advised, while also encouraging continuous monitoring of official forecasts and updates.
Residents are also being encouraged to report flooding or rising water levels to the National Emergency Monitoring System (NEMS) as authorities maintain close surveillance of the evolving weather system.
With conditions expected to persist for several days, officials are signalling that preparedness and early action will be critical to minimising risk and safeguarding communities.
