Light to moderate rain in the city and suburbs with the possibility of occasional intense periods, according to IMD

The Indian Meteorological Department (IMD) on Saturday said light to moderate rains in the city and suburbs with the possibility of occasional heavy spells.

IMD said on Saturday that the island city, eastern and western suburbs recorded 11.95mm, 15.91mm and 21.64mm of rain, respectively, in the past 24 hours.

Meanwhile, a high tide of 4.22 meters is expected at 2:34 p.m. in Mumbai. In addition, a low tide of 0.53 meters is likely to occur at 8:36 p.m. today.

When there is a high tide during the rainy season, it becomes difficult for the flooded waters to recede. The low tide helps the city’s floodwaters find an outlet to enter the seas.

Meanwhile, rainfall in August, which was 24% deficient, was the lowest in 12 years, the Indian Meteorological Department (IMD) said on Friday. Two major weak monsoon episodes prevailed over the country – August 9-16 and August 23-27 – as the northwest, central and west coast of the peninsula and western India slowed rainfall.

“In August 2021, precipitation across the country was below the long-term average (LPA) of minus 24%. This is also the lowest August precipitation in the 12 years after 2009,” IMD said in an updated statement.

In its previous statement, the IMD said the August 2021 deficit was the lowest in 19 years, since 2002.

The southwest monsoon season officially begins on June 1 and lasts until September 30.

June saw 10 percent more precipitation, but July and August recorded deficits of 7 and 24 percent respectively, according to IMD data.

The country received 24 percent less than normal precipitation in August.

Out of the four weather divisions of IMD, the Central Division of India received 39% less precipitation.

The division consists of a large area of ​​Maharashtra, Gujarat, Goa, Madhya Pradesh, Chhattisgarh and Odisha.

The deficit in the Northwestern Division of India, which includes the northern states of India, was 30 percent.

The deficit was 10 percent in the southern peninsula while the eastern and northeastern division received 2 percent more precipitation than normal.

The IMD had predicted that rainfall activity should be normal in August. He has now forecast above normal precipitation for September.

The weather forecasting agency said the intra-seasonal variation in week-to-week rainfall variation over India shows that monsoon rain activity has been largely moderate consecutively for three weeks – for the week ending. on August 11, 18 and 25 – when all of India the weekly cumulative rainfall for the entire country was 35 percent, 36 percent and 21 percent, respectively, below its LPA.

The formation of fewer low pressure systems (LPS) and their fewer days relative to climatology and the absence of their longer westward movements during August 2021 contributed to the large deficit of rainfall in central India as well as throughout India, says IMD.

He said that the Indian Ocean Dipole (IOD) negative over the tropical Indian Ocean, unfavorable to the Indian monsoon, prevailed throughout August, which also contributed to insufficient rainfall over the India during the month.

A negative IOD is associated with the warming of the waters of the Indian Ocean.
