New Delhi: The south­west mon­soon fi­nally be­gan its re­treat from the coun­try, nearly 40 days later than the nor­mal date, in what is by far the most de­layed mon­soon with­drawal in met depart­ment records go­ing back to 1960.

The In­dia Me­te­o­ro­log­i­cal Depart­ment de­clared that mon­soon had with­drawn from parts of Pun­jab, Haryana and north Ra­jasthan on Wed­nes­day. From here on, mon­soon is likely to make a swift re­treat from north and cen­tral In­dia, it said.

The most de­layed mon­soon with­drawal recorded be­fore this year was in 1961, when the mon­soon be­gan its re­treat on Oc­to­ber 1. This year, ac­tive con­di­tions till late in the season, in­clud­ing a low pres­sure sys­tem that came in from Bay of Ben­gal in Septem­ber end, kept mon­soon go­ing.

IMD said con­di­tions were now be­com­ing ripe for mon­soon to fur­ther with­draw from more parts of north­west In­dia, in­clud­ing Delhi, dur­ing the next two days. In the sub­se­quent twothree days, the rain-bear­ing sys­tem may re­treat from the re­main­ing parts of north­west In­dia as well as cen­tral In­dia, the depart­ment said.

“With the re­treat process hav­ing be­gun, we are likely to see a quick with­drawal of mon­soon,” said Mru­tyun­jay Mo­ha­p­a­tra, IMD’s di­rec­tor gen­eral of me­te­o­rol­ogy. The with­drawal was an­nounced af­ter per­sis­tent anti-cy­clonic cir­cu­la­tion and grad­ual re­duc­tion in mois­ture — the

two essen­tial con­di­tions for mon­soon’s re­treat — were ob­served, the IMD said.

“The re­ver­sal of wind di­rec­tion is likely to re­duce hu­mid­ity and lead to a drop tem­per­a­tures in north In­dia,” Mo­ha­p­a­tra said. The mon­soon typ­i­cally be­gins to with­draw from west Ra­jasthan, re­treat­ing in­cre­men­tally from the north and then cen­tral In­dia in a process spread over a month-and-a-half.
