NEW DELHI: Meteorological Department of India (IMD) on Monday announced the arrival of a southwest (summer) monsoon over the Andaman Sea and adjacent to the Bay of Bengal to the southeast 6 days ahead of its normal schedule and said favorable conditions for its further progress, leading up to its beginning Kerala on May 27 as predicted last week.
The advance of the southwest monsoon over mainland India is marked by its onset over Kerala, the beginning of the four-month rainy season. “In progress and follow-up, it shows that our prediction (for the onset of Kerala on May 27) will hold true for the monsoon,” said IMD scientist RK Jenamani. IMD RK Jenamani said while referring to the progress and occurrence in the Andaman Sea and adjacent southeastern Bay of Bengal.
Meanwhile, heatwave conditions over north-west and central India decreased significantly in intensity and distribution on Monday. “The maximum temperature could drop by 3-4 degrees Celsius over many parts of northwest India in the next 24 hours,” the IMD said.
Two cyclonic cycles – one over Lakshadweep and the other over Tamil Nadu coast – and strong currents from the west at Arabian sea level will bring heavy to very heavy rainfall over Kerala, the coastal and inland regions south of Karnataka over the next five days, and over parts of Tamil Nadu until May 18, IMD said.
On the other hand, a western disturbance currently in central Pakistan will result in scattered to moderate moderate/light rainfall over Jammu-Kashmir, Himachal Pradesh and Uttarakhand on Tuesday. Isolated hailstorms are also likely to overwhelm Himachal Pradesh and Uttarakhand over the next 24 hours. The meeting department also forecasts dust storms/thunderstorms in isolated places across Punjab, Haryana, Delhi, Uttar Pradesh and Rajasthan during that period.
