Above-normal rainfall, flash floods predicted for May – July – Hydromet Office

The Hydrometeorological Service of the Agriculture Ministry has predicted that there will be above-normal rainfall conditions over most of Guyana between May and July.
The forecast for this period indicates that the highest rainfall totals and the possibility of flash flooding during this season are expected to peak in May and June.
According to the seasonal forecast issued, rainfall amounts and frequency are expected to increase as the season progresses. It has been noted that, as the season progresses, water levels in the conservancies, reservoirs and rivers across all Regions are likely to increase. The potential of flooding because of rain is also expected to increase throughout May and June.
The highest amount of rainfall can be expected in Regions Three (Essequibo Islands-West Demerara); Seven (Cuyuni-Mazaruni); Eight (Potaro-Siparuni) and 10 (Upper Demerara-Berbice). However, all other regions can still expect higher-than- normal rainfall values.
The temperature outlook suggests that, except for some areas in Regions One (Barima-Waini) and 10, all other areas can expect cool as usual to cooler (below-normal) night-time temperatures. Warmer than usual (above-normal) day-time temperatures can be expected in northern Regions, while cooler than usual temperatures can be expected in the south.
The bulletin also noted that an increasing number of wet days and wet spells, coupled with high tides, could lead to water accumulation in coastal regions and disruption to transport, and possibility of landslides in hinterland areas.
“Flooding can lead to loss of crops and livestock, contamination of surface water, breeding grounds for mosquitos, and the proliferation of waterborne diseases. The Hydrometeorological Service has recommended the continued maintenance of drainage infrastructure as the country transitions into the wet season, and has urged farmers to take all necessary precautions to secure their crops and livestock,” said the Hydromet Office.
The Hydrometeorological Service has said it would provide updates to its seasonal forecasts as new information becomes available, and recommends that special attention be paid to short-range forecasts provided, in order to plan daily farming activities.
For short-range forecasts and weather analyses, stakeholders are advised to follow the daily weather briefs, outlooks and advisories produced by the National Weather Watch Centre, or visit www.hydromet.gov.gy. The forecast desk could also be reached at 261-2284 or 261-2216.
Since the beginning of May, Guyana has been subjected to increased rainfall. However, this has not resulted in any major accumulation of water, or flooding. The last major occurrence of inundation was in June 2021, when torrential rains resulted in mass flooding countrywide. Over 50,000 households were affected.
In the event of their being flooded, persons are asked to stay out of the water and keep food items safe. Water-borne diseases can be contracted through contact with these waters.
Direct contact with floodwaters can expose persons to several germs that can lead to any of these diseases. Guardians are also asked to keep children especially out of the water, as they are most at risk of contracting diseases; and everyone should avoid swimming in canals and trenches.
Protective gear should be used, and feet should be washed regularly after persons exit the waters. If necessary, Vaseline or oil can be applied to form a barrier to protect from the dirty water.
