1290 mm rain in 48 hours marked as an extremely rare weather event

Mumbai: The famed hill-station of Lonavala, which was battered by 670 mm rainfall in a day and 1290 mm in 48 hours on Sunday-Monday, is set to enter the record books for the ‘extremely rare’ weather event, scientists and climatologists said.
On July 5 and 6, Lonavala measured 670 mm and 620 mm rainfall, respectively, totalling to a staggering 1,290 mm in two days. Lonavala and its twin Khandala rank among the state’s most popular tourist hotspots, particularly attracting monsoon tourist crowds.
Scientists and meteorologists like K. S. Hosalikar former head of India Meteorological Department’s Climate Research & Services, Pune; IMD scientist Sakha Sanap; Mumbai Nowcast chief S. R. Khandelwal; research scientists Dr. Vineet Kumar; Dr. Vivek Shilimkar, Kokan Hawaman’s amateur forecaster Abhijit Modak; and others hailed the historic development in glowing terms on social media today.
“Lonavala, 670 mm rainfall received… 670 mm rainfall qualifies as a 1-in-1,000-year rainfall event, making it one of the rarest extreme weather events recorded in the region,” said Hosalikar.
“Highest rainfall in ghats: Davdi (688 mm), Lonavala (620 mm) on 6 July and many stations reporting extremely heavy rainfall. Rainfall intensity expected to reduce in coming days,” added Sanap.
“As Lonavala received 670 mm rain in 24-hours, we have witnessed a once in a lifetime event. As per IMD, the return period of such an extreme rainfall in Lonavala is 1000 years. This means only once in 1000 years, rainfall exceeding 650 mm occurs in Lonavala. Truly remarkable,” noted Dr Kumar.
“Lonavala is creating history… 1290 mm rains in Just 48 hours… 5 July (670 mm) and 6 July (620 mm),” posted Khandelwal.
“A 620+ mm rainfall is an event that occurs approximately once every 500 years and 670+ mm rainfall is an extremely rare event that occurs approximately once every 1000 years,” informed Dr Shilimkar.
“Lonavala has created a new All-Time Record (ATR), recording an extraordinary 670 mm of rainfall in just 24 hours, making it one of the most remarkable monsoon events ever observed over the Bhor Ghat section,” gushed Modak.
Rainfall Analysis
The evaluation was based on the Rainfall Frequency Analysis, as per IMD Central Water Commission (CWC) Atlas, 2015, and the records earned laurels from many on the social media.
The torrential downpour set off several hill-slides and landslides, disrupting rail and road traffic on the Mumbai-Pune Highway, Mumbai-Pune Expressway and the Central Railway route serving the country’s commercial capital with the state’s academic-IT-cultural hub.
Lonavala-Khandala – the latter made famous after the Aamir Khan-Rani Mukherjee frolicking number from the Hindi film, Ghulam, “Aati Kya KHandala…?” (1998) – are cuddled in the luxuriant green Western Ghats – a UNESCO World Heritage site since 2012, and are believed to be older than the Himalayas.
