Flooding possible as heavy rainfall expected over next six days – Hydromet warns

The Hydrometeorological Service has issued a warning for potential flooding across Guyana over the next six days, as unstable weather conditions are expected to bring widespread and at times heavy rainfall.

In a Special Information Bulletin issued on Monday, the National Weather Watch Centre said the period from March 23 to March 28, 2026 will likely see persistent showers, thunderstorms and reduced visibility, with conditions capable of triggering flooding, especially in low-lying and poorly drained areas.

According to the agency, the current weather pattern is being driven by strong low-level convergence combined with moisture from the trade winds, along with upper-level atmospheric divergence. These factors are creating a highly unstable environment conducive to cloud formation, frequent showers and periods of intense rainfall.

The Hydromet Office said these unsettled conditions are expected to persist throughout the week, with forecast models indicating little change in the atmospheric pattern.

Residents can expect widespread rainfall, which may be heavy at times, along with thunderstorms, particularly during the morning into early afternoon periods. Reduced visibility is also likely during intense showers.

The agency warned that the anticipated rainfall could lead to localized flooding and the worsening of existing water accumulation in vulnerable communities. Roadways may become hazardous due to water buildup, while outdoor activities could face disruptions.

Additionally, thunderstorms may be accompanied by lightning and gusty winds, posing further risks.

Flooding in Guyana is not uncommon during periods of intense rainfall, particularly in coastal and low-lying areas where water accumulation can occur rapidly. Previous advisories have highlighted the risk of water buildup and reduced visibility during heavy downpours, especially in flood-prone regions.

The Hydromet Service said it will continue to monitor the situation closely and issue further updates as conditions evolve.

Residents are advised to take necessary precautions, particularly those living in flood-prone areas, and to remain alert for additional weather bulletins.
