Indian Meteorological Department (IMD) has maintained the watch for ground frost to occur at one or two places over Punjab, Haryana, north Rajasthan and west Uttar Pradesh during for two more days.

This is even as a chill settled over the region in the immediate wake of a western disturbance having left the region towards the east.

POOR VISIBILITY

Visibility would therefore reduce to 200 m or less in dense fog over many parts of east Utter Pradesh and some parts of Bihar and sub-Himalayan West Bengal and Sikkim during the next two days.

But the IMD also kept out a watch for a fresh western disturbance to drift in from across the north-west border from Monday.

This could lead to a return of warmer climes for north-west India coupled with fog conditions.

Meanwhile, a feeble trough in the easterlies has been triggering some rains in the peninsular south. Rain or thundershowers would occur at one or two places over extreme south peninsular India until Monday.

DENSE FOG

During the last 24 hours ending Wednesday morning, dense to very dense fog was observed over many parts of east Uttar Pradesh and some parts of Bihar, sub-Himalayan West Bengal and Sikkim.

Minimum temperature fell by 1 to 2 degree Celsius at many places over northwest India and by 2 to 3 degree Celsius at many places over east India, north interior Karnataka and Telangana and changed a little elsewhere in the country.

Minimum temperatures were below normal by 2 to 4 degree Celsius at a few places over Punjab, Haryana, north Rajasthan, Delhi, west Uttar Pradesh, west Madhya Pradesh and north interior Karnataka.

LOWEST MINIMUM

The lowest minimum temperature of 2.4 degree Celsius was recorded at Churu (Rajasthan) in plains of the country.

Rainfall has occurred at a few places over Tamil Nadu and at one or two places over Kerala.
