The brief pause that westerly disturbances allowed themselves may be about to end with the India Meteorological Department (IMD) hinting the arrival of the “ice-breaker” system by Wednesday.

It has been almost a week since the last system, a weak one, signed off to the east of the country.

The clouding associated with the incoming system is currently parked over the Iran-Iraq-Afghanistan belt.

Meanwhile on Sunday, widespread rainfall occurred over Andaman and Nicobar Islands, an IMD update said, as a prevailing easterly wave-upper air cyclonic circulation combo held sway in the Bay of Bengal. Isolated rain was reported from Gangetic West Bengal and Orissa, IMD update largely underwritten by an upper air cyclonic circulation over Assam and neighbourhood.

A weather warning valid for Tuesday said that isolated hailstorms or thunder squalls would occur over Northeastern States.

The weather-maker trough in the lower levels running down from southwest Bihar to north-coastal Andhra Pradesh through Chhattisgarh and Orissa also influenced weather locally.

Maximum temperatures have risen by 2 to 3 deg Celsius over Rajasthan, Gujarat and Madhya Pradesh.

They are above normal by the same margin over parts of Punjab, Rajasthan, Gujarat and Konkan as the heating orchestrated by a ‘ridge' (high-pressure region) jutting in from West Asia flared up further to the north and northwest.The highest maximum temperature of 41.5 deg Celsius on Sunday was recorded at Bhira in Maharashtra, western parts of which is heating up due to proximity to the ridge.

Minimum temperatures rose by 2 to 4 deg Celsius over some parts of Rajasthan, Gujarat and Madhya Pradesh, an evening update by IMD said on Monday.
