New Delhi, Jul 24 (UNI) It has been a deficient Monsoon for South and Central parts of India till now this year though the rainfall in Northwest India during the season has been higher than average, the India Meteorological Department today said.

According to the IMD's review of the seasonal rainfall scenario between June 1 and July 23, the rainfall in South Peninsula has been 32 per cent lower than the Long period average (LPA) for the period, at 219.3 mm, while that in Central India has been 15 per cent lower than the LPA at 348.1 mm.

The rainfall in northwest India has actually been 43 per cent higher than the LPA, at 320.3 mm.

''The cumulative seasonal rainfall for the country as a whole during this year's Monsoon has so far been two per cent below the LPA,''the IMD said in a release here.

Out of 36 meterorological subdivisions, the rainfall has been excess over nine, normal over 12 and deficient over 15 subdivisions, the Met department said.

The worst situation was in Marathwada and Madhya Maharashtra where the rainfall received between July 1 and July 23 was 62 per cent and 49 per cent lower than LPA respectively. In north interior Karnataka, the rainfall was 53 per cent lower than LPA while in Kerala, it was 43 per cent lower than LPA.

Assam and Meghalaya recieved rainfall 26 per cent lower than LPA while rainfall in Nagaland, Tripura, Manipur and Mizoram was 26 per cent lower than LPA. The rainfall in Gujarat was 36 per cent lower than LPA while that in Saurashtra and Kutch was 35 per cent lower than LPA.

Infact, during the past week, rainfall activity over South and Central India in particular and the whole of India in general remained subdued.

''During this week, monsoon trough remained north of its normal position with its axis lying close to foothills of the Himalayas.

Consequently, rainfall activity remained confined mainly over Gangetic plains, northeastern states and Sub-Himalayan West Bengal and Sikkim.

The parts of south peninsula such as Coastal Andhra Pradesh, Rayalaseema and Tamil Nadu has also received normal to excess rainfall. The rainfall activity was generally sub-dued over remaining parts of the country. During this week, rainfall over the country as a whole was 33 per cent below the Long Period Average (LPA).

The deficient rainfall in south and central India notwithstanding, conditions were favourable for revival of Monsoon activity in these areas in the coming days.

''The current meteorological analysis and numerical weather prediction models suggest southward shift of monsoon trough from tomorrow onwards. Subsequently, a low pressure area is likely to form over west-central and adjoining northwest Bay of Bengal around July 27. This development is considered as a signal for revival of Monsoon activity along the West Coast and over Central and adjoining peninsular India,''the IMD said.
