See full statement from the Hydrometeorological Service:
The Hydrometeorological Service advises that unstable weather conditions are expected to affect Guyana over the next six days (March 23–28, 2026), resulting in widespread rainfall with the potential for flooding and, in some cases, exacerbating existing flooding, particularly in low-lying and poorly drained areas.
Synoptic Analysis
Current weather conditions are being influenced by strong low-level convergence, supported by moisture transport from the trade winds. This is further enhanced by upper-level divergence, creating a highly unstable atmospheric environment.
These combined factors are contributing to increased cloudiness, frequent showers, periods of moderate to heavy rainfall, and isolated to scattered thunderstorms.
FORECAST OUTLOOK
These unsettled conditions are expected to persist throughout the week, as forecast models indicate that the current atmospheric pattern will remain in place.
WHAT TO EXPECT
- Widespread rainfall, at times heavy
- Thunderstorms, particularly during the morning into early afternoon periods
- Reduced visibility during intense showers
Potential impacts
- Localized flooding, especially in flood-prone and low-lying areas
- Water accumulation on roadways leads to hazardous driving conditions
- Disruptions to outdoor activities
- Lightning and gusty winds associated with thunderstorms
