The amount of rain received in Mumbai and suburbs has been less than half of the monthly average, making this July the driest month in a decade.
Officials from the India Meteorological Department (IMD) said on Friday that the amount of rainfall at the end of July has been 359.1mm for Santacruz and 280.2mm for Colaba. The monthly average is 799mm for July.
The quantum of rainfall received during the month of July in 2014 was 1,468.5mm, highest in a decade, followed by 2005, where the rainfall was 1,454.5mm in July.
KS Hosalikar, deputy director general, western region, IMD, said, “From the last week of June to the third week of July, the rain-bearing systems were not active. The western part of the monsoon trough was near the foothills of the Himalayas, weather systems over Bay of Bengal and Arabian Sea were not very active.”
Hosalikar said such things caused subdued rainfall over peninsular and central parts of India.
According to data from the Met department, the country has witnessed a 4% deficit in rain for the season till July 31, while Maharashtra, Madhya Pradesh, northern Karnataka and southern Uttar Pradesh observed 19% deficit for the season.
“While areas like central Maharashtra and Konkan observed a 24% deficit, the biggest concern is the 55% deficit observed in interior Maharashtra [Marathwada],”said Hosalikar.
Mumbai, on the other hand, observed a mix bag. Due to heavy rain in the second last week of June, the quantum of rain recorded in Santacruz has been 1,465.8mm, 107mm above normal, but Colaba observed deficient rain at 1,146.5mm, 143.8mm below normal.
Meanwhile, the quantum of rain has decreased in the city and suburbs over the past two days with Colaba and Santacruz recording only 1.6mm and 1mm rain respectively till 8.30pm on Friday.
“All the factors inducing rain such as the off-shore trough, the low pressure gradients over Rajasthan and the Bay of Bengal are slowly fading away. The rainfall is expected to gradually reduce over the next few days,” said VK Rajeev, director, western region, IMD.
