The Hydrometeorological Service has advised 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.
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.
The unsettled conditions are expected to persist throughout the week, as forecast models indicate that the current atmospheric pattern will remain in place. Residents may experience widespread rainfall at times heavy, thunderstorms particularly during the morning into early afternoon periods, and reduced visibility during intense showers.
Hydromet warns that the potential impacts include localized flooding, especially in flood-prone and low-lying areas, water accumulation on roadways leading to hazardous driving conditions, disruptions to outdoor activities, and lightning and gusty winds associated with thunderstorms.
The National Weather Watch Center will continue to closely monitor the event, including using the satellite image (14:30 hrs) and a six-hour radar-generated precipitation accumulation for March 23, 2026, and will issue bulletins as the need arises.
