ITCZ arrives with record rainfall

On November 27th Georgetown experienced severe flóoding as intense rainfall began in the very early morning and lasted for about 6 hours. Away from the capital rainfall was less.
According to the Hydrometeorological office as reported in the Chronicle the Intertropical Convergence Zone (ITCZ) "shifted from its last position, to about 6 degrees North of the equator bringing it directly over Guyana's Coast."
"This 6 hour rainfall of 128.9mm or 5.1 inches which was recorded at the Botanical Gardens was the highest recorded data analysed for Georgetown since 1892... This morning's rainfall had an intensity of 21.5mm per hour, compared to 6.9mm per hour in 2005".
Where I live some 10km away the rain was heavy but not unusual for the season.
