Beating retreat? Not yet, says weatherman
For Just Third Time In 10 Years, Monsoon Likely To Stay In Delhi Beyond September 30
New Delhi: Monsoon is likely to stay longer in the national capital. It usually retreats from Delhi on September 30, but according to India Meteorological Department (IMD) officials, it may be delayed by nearly two weeks this year.
Monsoon generally retreats from Rajasthan on September 1, but IMD officials said that the neighbouring state was still recording wet days this time. Hence, the season of showers is likely to extend in Delhi up to October’s second week, which will coincide with Dussehra days. In that case, you might have to carry an umbrella while doing pandal hopping across the city.
“In the past two years, we have seen the retreat taking place on September 30, which is the usual date. However, it will be delayed by at least 1-2 weeks this year. We will once again assess the situation on October 5. A wet Dussehra is possible this time,” Kuldeep Srivastava, scientist at IMD, told TOI.
Both in 2018 and 2017, the retreat of monsoon in Delhi was witnessed on September 30, while it was delayed by over a week in 2016 (October 7, 2016). The monsoon season stayed for the longest in Delhi in 2013, when the retreat was declared on October 17. Since 2010, the retreat has only been delayed twice.
Srivastava further said that they were closely studying the retreat of monsoon for Rajasthan, which begins in west Rajasthan from September 1. Light spells of rain are still occurring there, with another spell likely to lash the neighbouring state on September 26 and 27 – pushing Delhi’s date with monsoon retreat further ahead.
“In east Rajasthan, we are recording continuous monsoon activity and rainfall at as many as 75 stations. In west Rajasthan too, we are recording light spells. There is forecast for another spell of rain for two days from September 26. Going by the developments there, we can safely say that Delhi will miss its normal deadline of September 30 for retreat, and the delay should be at least 1-2 weeks,” said Srivastava.
Meanwhile, the capital is reeling under a monsoon deficit of 36%. Delhi has recorded a rainfall deficit in all four months of June, July, August and September.
Monsoon reached the capital a week late this year on July 5 as against the usual date of June 29. There was an 83% rainfall deficit in the month of June. Only 11.2mm of rainfall was recorded in the first month of monsoon as against a normal of 65.5mm. In July, 210.4 mm rainfall was received as against a normal of 276.1mm (24% deficit) and in August, 119.6mm was recorded as against a normal of 247.4mm (52% deficit).
Until September 23, 73.8mm of rainfall has been recorded as against a normal of 104.2mm, which is a deficit of 29%.
“There is a deficit of over 200mm so far this monsoon season with only 403.8mm of rainfall recorded till September 23 as against a normal of 628mm. This deficit, however, should come down due to a prolonged monsoon season,” said a weatherman.
