Dense Fog to Cover North West UP Till Tomorrow

Inside the forecast  
IMD’s latest bulletin highlights dense fog formation driven by cooling night temperatures and light winds, likely to impair visibility during early hours in northwestern UP districts. Concurrently, a well-marked low-pressure system over the Andaman Sea is set to intensify, bringing heavy to very heavy rain to Tamil Nadu, Kerala, and the Andaman & Nicobar Islands, alongside squally conditions over adjacent seas.

Notable updates  
- Dense fog window: Northern parts of West Uttar Pradesh to see dense fog till tomorrow morning, impacting early travel and logistics  
- Marine advisory: Squally weather likely over Andaman Sea, off north Tamil Nadu coast, and central Bay of Bengal; caution urged for fishers and small vessels  
- Rain alerts: Heavy to very heavy rainfall at isolated places in Tamil Nadu, Puducherry, Karaikal, Kerala, Mahe, and Andaman & Nicobar Islands  
- Air quality context: Delhi-NCR remains in the “very poor” category, compounding morning visibility and health concerns for commuters

Major takeaway  
Expect reduced visibility across northwestern UP during early hours; delay non-essential travel, use fog lights, and follow local advisories. Coastal and marine stakeholders should heed IMD warnings as the Bay of Bengal systems strengthen, with significant rain and squally conditions across southern maritime zones.
