Showers are expected at most places over Gujarat and southeast and north Rajasthan during the next twenty four to forty eight hours as the low pressure area has moved upward in a northwest direction and now lies over Gujarat and adjoining areas of south Rajasthan. Heavy to very heavy showers are predicted at one or two places over these areas during the next twenty four hours.
The weather system is expected to move further in the northwest direction and would be placed over northwest Rajasthan and adjoining areas of Pakistan during the next twenty four to forty eight hours. This system and the cyclonic circulation persisting over coastal Gujarat and the adjacent Arabian Sea would interact with the passing Western Disturbances over north Pakistan and Jammu and Kashmir in India. This would increase intensity of the rainfall over Jammu & Kashmir and Punjab especially in western Punjab region during this period.
In the eastern region, rains are increasing over east Madhya Pradesh, Chhattisgarh, Jharkhand, Gangetic West Bengal and Orissa. Many places over these areas would receive rain as a cyclonic circulation lies over West Bengal and adjoining the Bay of Bengal. The presence of the monsoon trough over these areas would also increase the possibilities of the rain in these areas.
The monsoon trough is passing through Barmer, Nimach, Sagar, Ambikapur, Ranchi, Digha and thence southeastwards to the Bay of Bengal. Monsoon trough is essentially a region of intensified monsoon winds.
The rain over the northeastern states would remain light as the most of the moisture in the southeasterly winds is flowing in a northwest direction towards inland. The incursion of the moist southeasterly winds is reaching up to Haryana, Delhi, Uttar Pradesh and Bihar. This would translate into light rain over these areas. The main factor would be the speed of the southeasterly winds which if slowdown at a place, it would experience increased rainfall.
Along the west coast Konkan, Goa and Kerala would continue to receive moderate rain At a few places rains could be heavy to very heavy as the offshore trough is active and extending from the Gujarat coast to Kerala coast. In the Southern Peninsula, rains are expected at one or two places over north Tamil Nadu as the westerly winds from the Arabian Sea are making a tilt while reaching the northern coastal areas of the state.
