The India Meteorological Department (IMD) said strong northeasterly winds from the Bay of Bengal will cause light to moderate rain over the Tamil Nadu coast for three more days from Saturday. Tamil Nadu, Puducherry and Karaikal will remain isolated on Saturday and moderate over Kerala, Mahe and Lakshadweep for the next five days.
Moist spell to NW
Meanwhile, another western disturbance is likely to affect NW India from Friday and WN winds may affect the eastern Gulf, causing wet weather over NW India and adjacent central India from Saturday to Tuesday. On Tuesday morning, the unrest in southeast Iran shrouded Punjab, Haryana, Delhi, eastern Uttar Pradesh, western Madhya Pradesh and pockets of Odisha in a thick blanket of fog for the 24 hours that ended in the morning. It was moderate over West Uttar Pradesh and low over coastal Chandigarh, Bihar, Andhra Pradesh and Tripura.This reduced visibility to zero in Amritsar, Patiala, Palam, Ambala, Varanasi, Prayagraj, Guna and Paradip, up to 200 meters in Safdarjung, Jhansi and Lucknow, and 500 meters in Chandigarh, Gwalior, Bhubaneswar, Purnea, Vijayawada, Agartala and Kailashahar. Western disturbances play an important role in strengthening the winter weather over Northwest, Central and East India. A Western Disturbance is a low-pressure wind belt that often passes through Iran, Afghanistan and Pakistan before reaching northwestern India. Before them is a “steam engine” that spews cloud-forming moisture, snow or rain over the hills and lightning or thunder on the plains. The temperature behind them cools, causing an occasional chill. Depending on whether the air is already cool from the previous disturbance, dense fog conditions will develop upon arrival.
Minimum temperature will increase
Minimum temperature is currently 6-10°C over Punjab, Haryana, Chandigarh, Delhi and West Uttar Pradesh due to disturbance due to cloud formation and 11-12°C over Rajasthan, East Uttar Pradesh, North Madhya -Pradesh and parts of Chhattisgarh and Jharkhand. They are 2-3°C above normal in parts of Punjab, West Rajasthan, Uttar Pradesh, North Odisha and Madhya Pradesh, in many places in Bihar, Jharkhand, West Bengal plains, Gujarat and Northeast India. According to the IMD, dense to very dense fog conditions may persist in pockets of Punjab, Haryana, Chandigarh, Delhi and Uttar Pradesh during the early morning hours for the next three days as the disturbance closes in and moves towards Afghanistan and Pakistan. Dense to very dense fog may occur over Rajasthan and North Madhya Pradesh on Tuesday and Wednesday. Fog moves into eastern IndiaThese conditions may spread eastward as the disturbance moves into isolated pockets over Odisha on Tuesday and Wednesday, Uttarakhand for three days from Tuesday, over Jammu and Kashmir on Wednesday and Thursday, across Punjab, Haryana, Chandigarh, Delhi and Uttar Pradesh on Friday and Saturday, and further east across Assam, Meghalaya, Nagaland, Manipur, Mizoram and Tripura for five days from Tuesday.
