MUMBAI – The depression over southeast Bay of Bengal and the adjoining east equatorial Indian Ocean intensified into a deep depression over the same region in the early hours of Thursday, the India Meteorological Department said. Currently, it is located 810 km away from the coasts of Karaikal, Puducherry, and 980 km away from the southeast coast of Chennai, Tamil Nadu, the weather department said.
This weather system is likely to cause heavy to very heavy rainfall accompanied by thunderstorms and lightning over parts of Tamil Nadu on Friday and Saturday and over parts of Kerala on Saturday, the department said.
The weather bureau has warned of dense to very dense fog during the morning hours in parts of Punjab, Uttar Pradesh, and west Rajasthan till Friday, and over east Rajasthan till Saturday. Dense fog conditions are likely over most parts of northwest and northeast and some parts of east and central India till Thursday, the bureau said.
Visibility drops to 0–50 metres in "very dense fog" conditions, and between 51 and 200 metres in "dense fog" conditions.
Cold day conditions are likely to prevail in parts of Punjab, Haryana, Chandigarh, Rajasthan, and east Madhya Pradesh till Friday and in Bihar till Saturday, the weather department said. Cold wave conditions are expected in isolated pockets of Himachal Pradesh, east Madhya Pradesh, Chhattisgarh, Jharkhand, Odisha, and north interior Karnataka on Friday and Saturday and over Punjab, Haryana, Chandigarh, and Rajasthan from Friday to Sunday, 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.
Ground frost conditions are likely in parts of Uttarakhand till Saturday, the weather bureau said. Ground frost is a covering of ice, in one of its many forms, produced by the sublimation of water vapour on objects colder than 0 degree Celsius.
No significant change in minimum temperature is expected over the plains of northwest India, east India, and Gujarat over the next seven days, the department said. In central India and Maharashtra, the minimum temperature is likely to gradually rise 2–3 degrees Celsius in the next four days, it said.
In northeast India, no significant change in minimum temperature is likely in the next two days, after which a gradual rise by 3–4 degrees Celsius is expected, the weather department said. End
