Heavy rains, flood loom from today
…as Hydromet Dept predicts unstable weather system
(Kaieteur News) – The Hydrometeorological Service advises that unstable atmospheric conditions will affect Guyana from April 22 to 25, 2026, bringing widespread rainfall and an elevated risk of flooding—especially in low-lying and poorly drained areas.
While conditions remain highly dynamic, the latest model guidance indicates that Regions 5, 6, 7, 8, and 9 are likely to experience the heaviest rainfall during this period.
SYNOPTIC ANALYSIS
Unstable atmospheric conditions associated with a surface trough are expected to begin affecting Guyana from the evening of April 21 into the early morning of April 22, 2026. Thereafter, a gradual strengthening and oscillation of the inter-Tropical Convergence Zone (ITCZ) over the country will persist throughout the remainder of the week. These conditions are likely to be further enhanced by strong upper-level divergence.
These combined factors are contributing to increased cloudiness, frequent showers, periods of moderate to heavy rainfall, and isolated to scattered thunderstorms.
FORECAST OUTLOOK
Unsettled conditions are forecast to continue for the remainder of the week, as meteorological models indicate that the projected atmospheric conditions will remain in place. While there are some indications of a temporary reduction in rainfall activity over coastal areas on Thursday, other parts of the country are still expected to experience cloudiness, showers, and possible thunderstorms due to ongoing instability.
Rainfall amounts are likely to average between 50mm (-2 inches) and 75mm (-3 inches) in 24 hours; however, some areas may record more than 100mm (-4 inches) in 24 hours.)
WHAT TO EXPECT
Widespread rainfall, at times heavy.
Thunderstorms (lightning, thunder, increased wind speeds), particularly during the early morning and late afternoon into evening periods.
