Monsoon covers ground: Mumbai gets 97% of June rain in two days | Mumbai News


MUMBAI: The much-delayed monsoon arrived with a bang, toppling some records and covering 97% of the average required June rainfall in two days.

In 24 hours ending Saturday 8.30am, the Santacruz observatory of the India Meteorological Department (IMD) recorded 234.8mm-highest 24-hour June rain since 2015. On June 19, 2015, Mumbai received 283.4mm rainfall. Also, it is the second highest rainfall recorded in Mumbai in a 24-hour period in the last decade. According to IMD, rain greater or equal to 204.5mm is extremely heavy.
Heavy showers lashed the neighbouring areas of Thane and Navi Mumbai too in the same period with Thane recording 237.5mm rain while Navi Mumbai witnessing 245.2mm.
The 234.8mm rainfall received in a single day (24 hours) was almost 46% of the required June rainfall of 505mm. Since monsoon onset on Tuesday, it has already rained 97% (491.4mm) of the required June rainfall (see graphic). On Saturday, the rain recorded till evening at Santa Cruz was 69.2mm, which is in heavy rain category, while Colaba recorded 51.9mm.
While the rainfall refused to subside the entire of Saturday, keeping Mumbaikars mostly indoors, its intensity may reduce on Sunday, according to IMD forecast. The IMD has lowered its heavy rain warnings. From “heavy rains” on Saturday, the IMD said on Sunday “heavy rain is likely at isolated places in city and suburbs”. “While the intensity of rainfall is expected to reduce, the cloudy weather with intermittent showers as well as strong winds are likely. We warned fishermen about the gusty winds,” said K S Hosalikar, deputy director general (meteorology), Regional India Meteorological Department.
“Over the west coast, monsoon has been vigorous. We are not referring to it as active as that is one step below vigorous. There were two reasons for the sustained rainfall: One is strengthening of westerly winds, whose depth was very high. If you see the radar images, the westerly winds were at a lower level but now, they are almost 3km high. Secondly, there is a cyclonic circulation near south of Gujarat,” he added.
Next week, the IMD is expecting enhanced rain in the interior of the state from July 2 to July 6 as a low pressure system will form over Bay of Bengal.
Private forecasting agency Skymet has forecast another heavy spell around July 4, when low pressure forms over the Bay of Bengal. “On July 2 and 3, Vidarbha and Marathwada may get heavy rain and on July 4, the intensity will increase over Mumbai,” said said Mahesh Palawat, vice-president, meteorology & climate change, Skymet.
