WEATHER ADVISORY
Weather Review
Over the last 48 hrs Guyana’s weather has been influenced by the presence of a surface low which was positioned over West of Guyana and over Venezuela. Due to the south westerly wind pattern over Guyana at the surface and strong upper level divergence moisture was advected over Guyana’s Inland and Coastal areas making environmental conditions favorable for the enhancement of deep convective cells that produced intermittent rain and outbursts of thunder.
The Hydrometeorological Service as at 0800hrs on October 19, 2011 received reports from a number of its rainfall stations across the country. The records indicate that the highest rainfall over 24 hr period – 0800 hrs on October 17, 2011 to 0800 hrs on October 18, 2011 was at Naamryck in Region 3 with 79.0 mm (3.1 inches), 64.9 mm (2.5 inches) which occurred at Vryheid’s Lust, Region 4 was the second highest amount of rainfall recorded, 60.2 mm (2.4 inches) at Uitvlugt Region 3.
OUTLOOK
During the next 72 hrs mostly cloudy conditions can be expected with occasional thundershowers, rainfall may exceed 25.0 mm on each day, mostly along Coastal and near Inland locations as there is a series of tropical waves expected to propagate over our area and influence our weather.
La Niña conditions have returned and are expected to gradually strengthen and continue into the early part of 2012.
Therefore Guyana should expect more days with rainfall above long term average in the coming months.
