The southwest monsoon on Wednesday covered the entire country after its arrival at Kerala coast on June 8, with most parts of the country receiving adequate rainfall, especially in the last two weeks.
“The monsoon has advanced into remaining parts of north Arabian sea, Kutch and west Rajasthan. Thus, it has covered the entire country,” India Meteorological Department (IMD) said in a statement.
According to IMD, the average volume of rainfall during June 1-July 13 has been more than 289 mm (mm) which is 4% more than the benchmark – Long Period Average (LPA). Till now, 34% of the area has got ‘excess’ rainfall while 45% have received ‘normal’ rainfall. Only 21% of the areas have received deficient rainfall.
With the exception of Saurashtra, Kutch, Gujarat and Bihar regions, where rainfall has been ‘deficient’, most of the regions across the country has so far received ‘normal’ or ‘excess’ monsoon rainfall.
IMD categories monsoon rains under four categories — <90% of benchmark (deficient), 90-96% (below normal), 96-104% (normal) and 104-110% (above normal) and 110%> (excess).
Meanwhile, the Met department has predicted heavy rain over east and west Uttar Pradesh, Bihar, Uttarakhand, Jharkhand, West Bengal, Kerala, Punjab, Rayalaseema, coastal Karnataka, South interior Karnataka over the next few days.
While June rainfall constitute 18% of the total rainfall received during monsoon (June-September) period, the showers during July (33%) and August (29%) are critical for kharif sowing. Because of excess rainfall so far in July, the kharif sowing of crops such as paddy, oilsedd and pulses have been less by 6% than in the corresponding period last year.
After two successive years of deficient monsoon (2014 and 2015), IMD last month had reiterated its April prediction by stating that southwest monsoon would be ‘above normal’ rainfall at 106% of the benchmark LPA, with a model error of ± 4%. The heartening part of the IMD’s forecast was that there is 96% probability of monsoon (June-September) being normal or excess.
