Present Meteorological conditions are favourable for onset of Monsoon over Kerala in the next 24 hours said India Meteorological Department (IMD) on Monday evening.
The season’s first cyclonic storm ‘Mora’,forming over the Bay of Bengal will likely turn into a severe cyclonic storm in the next 12 hours, helping further advance the southwest monsoon into parts of Arabian Sea and Bay of Bengal.
IMD also said onset is likely over Lakshadweep, coastal Karnataka, some parts of Tamil Nadu and most parts of northeastern states in the next 24 hours.
The onset of southwest monsoon over Kerala signals the arrival of monsoon over the Indian subcontinent and represents beginning of rainy season in the region.
A warning issued by the local Met Office said that strong westerly winds occasionally reaching 45- to 55 km/hr in speed are likely along and off Kerala and over Lakshadweep until Tuesday noon.
Deep depression in Bay of Bengal
After deep depression was reported in the Bay of Bengal, the Monsoon in the southern state of Kerala is likely to hit today. The reports have it that the deep depression in the Bay of Bengal can also cause “severe cyclonic storm” on May 30 night in Kerala, the MeT department said.
India Meteorological Department (IMD) Director General KJ Ramesh said the deep depression in the Bay of Bengal would help in the advancement of monsoon over Kerala and also over the Northeast India.
Meanwhile, pre-monsoon showers have been normal over the South Peninsula, Bengal, Uttar Pradesh, the North-Eastern States and Jammu & Kashmir. Rajasthan and Bihar received excess precipitation during this season.
But elsewhere, the rains were deficient or scanty. Falling under this category are some of the big states, such as Maharashtra, Gujarat and Madhya Pradesh, where rains were scanty.
Pre-monsoon rain was deficient in Andhra Pradesh, Telangana, Chhattisgarh, Himachal Pradesh, Punjab and Haryana.[irp]
