101mm rain in 1 hour brings Pune to a halt

The Times of India (Mumbai edition) - - TIMES NATION - Neha.Madaan@ times­group.com

Pune: A heavy down­pour that lasted barely an hour in­un­dated the city with 101mm rain on Fri­day evening. In the usual af­ter­math, roads were wa­ter­logged, traf­fic crawled and power sup­ply failed in parts of the city.

The In­dia Me­te­o­ro­log­i­cal De­part­ment (IMD) tagged the rain as Pune’s heav­i­est spell of the sea­son this year, that too in a short span of time. Though the shower lasted only an hour, it sur­passed 24-hour rain records of the last six years for Oc­to­ber.

Ac­cord­ing to IMD’s def­i­ni­tion, if a rain spell gives over 100mm in one hour, it is called a “cloud­burst”. J R Kulka­rni, re­tired sci­en­tist from the In­dian In­sti­tute of Trop­i­cal Me­te­o­rol­ogy, said a phe­nom­e­non can be termed as a “mini-cloud­burst” when a spell gives over 50mm but less than 100mm in an hour. “There are in­stances when heavy rains oc­cur dur­ing the re­treat­ing mon­soon,” he said. IMD of­fi­cials told TOI t com­bi­na­tion of fac­tors brought on the down­pour: con­vec­tion or heat­ing in the city dur­ing the last few days of Oc­to­ber and as a sys­tem over the Ara­bian Sea. IMD has in­di­cated more thun­der­show­ers and light­ning for the week­end in Pune, Konkan, and Vi­darbha.
