MUMBAI – Dense to very dense fog conditions are likely to persist during the night and early morning hours in most parts of Punjab, Haryana, and Chandigarh till Wednesday, in west Uttar Pradesh till Monday, in east Uttar Pradesh till Monday and from Jan. 8–9, and in Odisha till Tuesday, the India Meteorological Department said.
Dense fog conditions are expected to continue over most parts of northwest and northeast India and in some parts of east and central India till Jan. 9, the weather department said. Visibility in "very dense fog" conditions drops to 0–50 metres and between 51 and 200 metres in "dense fog" conditions.
The weather bureau has warned of ground frost in parts of Uttarakhand till Friday. Ground frost is a covering of ice, in one of its many forms, produced by the sublimation of the water vapour on objects colder than 0 degree Celsius. Ground frost occurs when the temperature of the upper layer of the soil is less than 0 degree Celsius.
Cold day conditions are expected in parts of Bihar on Sunday and Monday, the weather department said. Cold wave conditions are likely to prevail in Himachal Pradesh over the weekend, in Punjab from Sunday to Tuesday, in Haryana, Chandigarh, and Delhi from Saturday to Tuesday, and in Rajasthan on Jan. 8–9, the department said.
A cold wave condition is when the minimum temperature drops to 10 degrees Celsius or less for plains and 0 degree Celsius or lower for hilly regions, according to the weather bureau. Cold day conditions are associated with a fall in maximum temperatures, typically occurring due to persistent low clouding. A cold day occurs when the maximum temperature during the day is at least 4.5 degrees Celsius below normal.
In the past 24 hours, heavy to very heavy rainfall with a few instances of extremely heavy showers were recorded in Tamil Nadu due to the presence of a trough originating from a cyclonic circulation over the southwest Bay of Bengal off the Sri Lanka coast. These weather systems also caused heavy rainfall over parts of Kerala, the department said.
The minimum temperature over northwest India is expected to fall gradually in the next three days, the weather bureau said. In central India, no significant change in minimum temperature is likely in the next 24 hours, after which it is seen falling by 2–4 degrees Celsius in the subsequent three days, the bureau said.
In east India, the minimum temperature is likely to rise slowly by 2–3 degrees Celsius in the next two days, and thereafter a fall by 2–3 degrees Celsius is expected in the subsequent five days, the weather department said. A gradual rise in minimum temperature is seen by 2–3 degrees Celius over Maharashtra in the next three days, it said.
In Gujarat, no significant change in minimum temperature is likely during the next 24 hours, after which it could rise gradually by 2–3 degrees Celsius in the subsequent three days, the weather bureau said. End
