The south-west monsoon is likely to set over Kerala during the week beginning May 22 (Thursday next), India Meteorological Department (IMD) has said in its latest assessment. The national weather forecaster has already gone on record indicating the onset to unfold around May 27 here, with a model error of plus/minus 4 days.
The Bay of Bengal arm of monsoon may advance over North-East India simultaneously as the Arabian Sea arm enters the Kerala coast during the week under reference, IMD said in its extended outlook issued on Thursday. Passing western disturbances will trigger isolated to scattered rain and thunderstorms over hills of North-West India on some days of the week.
Monsoon can progress into northern parts only after these disturbances switch off activity. Disparate troughs/cyclonic circulations rustled up by them may set off strong westerly winds along west coast; and moderate/scattered/fairly widespread rainfall, thunderstorms and lightning across central, east and south Peninsular India during many days of the week.
Isolated heavy to very heavy rainfall is also likely along west coast (Konkan and Go; Coastal Karnataka; and Kerala) during many days of the week leading to above normal rainfall overall, accompanied thunderstorms and lightning over East, Central and South Peninsular India. Activity may be below normal over many parts of North-West and North-East India during the week.
Neutral (neither monsoon killer El Niño or rain-friendly La Niña) conditions prevail over equatorial Pacific, IMD said in a background assessment. But wind circulation features in the atmosphere still mirror La Niña conditions, which may explain ongoing vigorous pre-monsoon showers over India. Overall rain deficit has reduced to just -2 per cent as on Thursday.
Latest Monsoon Mission Climate Forecast System (MMCFS) of IMD as well as other climate model forecasts indicate that the ‘neutral’ conditions are likely to continue over equatorial Pacific during the monsoon season, which IMD expects to deliver above-normal rainfall (105 per cent) this year. Most global models converge with this outlook.
It is likely ongoing pre-monsoon weather activity may seamlessly merge into onset of monsoon over Kerala coast. An official announcement of its arrival over Sri Lanka, the penultimate station, is awaited. Morning satellite pictures on Friday showed a rain cover over parts of coastal Kerala as well as adjoining coastal Karnataka just to the north.
To the immediate east, a cloud cover extended across Tamil Nadu and hills bordering Kerala, Rayalaseema and Telangana, and to further north an north-west, over parts of Goa and adjoining interior Maharashtra (Madhya Maharashtra). Winds continue to be north-westerly over Kerala coast while being monsoon-friendly westerly to south-westerly over Sri Lankan coast.
