The cyclonic circulation or the low pressure area over north Madhya Pradesh and south Uttar Pradesh has moved and now persists over south Uttar Pradesh adjoining north Madhya Pradesh. It will be responsible for rainfall activities over east Rajasthan and Madhya Pradesh. Heavy showers are anticipated at one or two places over these areas while moderate rain at many places would continue to happen during the next twenty four hours.
After this period, the low pressure area is likely to move in a northwest direction to reduce rain over the southern parts of central India. However, the northern parts of central India in Madhya, central Uttar Pradesh, east Rajasthan would continue to with rain during the next forty eight hours. Rain would reduce over west Madhya Pradesh and Vidarbha.
The west coast is likely to continue with light rain as the offshore seasonal trough is feeble. The trough extends from the Maharashtra coast to Kerala coast. The coastal areas of Konkan, Goa, Karnataka and Kerala would receive light to moderate rain during one or two days. In the Southern Peninsula, rains are continuing to be scanty.
