Intense rainfall on 14 June (76.5 mm/h)


 
 Early rainy season and early summer conditions today with high humidity and strong sunshine, but not such high temperatures yet (just below 30 degrees). The hydrograph above shows four sizable rainfall events, with the largest on 4 June producing a stage of 0.8m and followed by a long flow recession to below 0.4m. On the evening of 14 June there is a very short and intense burst of rainfall (76.5 mm/h at Miomote Amedas gauge) which gives a very sharp peak and rapid decline back to baseflow conditions.

Today the river stage had dropped to 0.372m (discharge measured at 0.458 m3/s) which is one of the lowest levels for the season so far. Depending on the timing of the heavy rains expected during rainy season (late June to late July), flows may fall much lower still.

Stage = 0.372m, Discharge = 0.458 m3/s
