Retreating Monsoon thunderstorms got the better of Western and southern Maharashtra again on Wednesday evening. As the cumulo nimbus clouds developed, a superbly conducive atmosphere around the region made massive thunder heads rise to 18 kms above sea level, and created an internal 2 level basis within the clouds to ignite lightning within the cloud system itself. Developing west 200 mb jet streams inter-acting with the "departing" SE jet winds, cause massive thunder reactions during a withdrawing monsoon.
Today evening, Rajgurunagar got 50 mms, Satara 46 mms, Pashan got 16 mms, Mahableshwar 18 mms,
Massive storms rolled towards Mumbai by the evening, and resulted in heavy precipitation in many parts of the city. Extreme lightning and deafening thunder shook the city. By evening, upto 8.30 pm, SantaCruz measured 59 mms and Colaba 32 mms. south Mumbai at my residence, 44 mms were measured till 9.30 pm.
Yes, this has taken the author by surprise. If, we had been waiting for this thunderstorm farewell since 25th September, and it happens, after all the monsoon "settings" are over and done with, definitely it is a surprise and was not expected today. Not in Mumbai, but restricted to South Konkan and South Mah.
svt: Please note while reading the wundermaps, these are up graded at 12.30 pm, 6.30pm and 12.30am IST everyday. Not every hour.
