A depression in the Bay of Bengal will bring downpours and the threat for flooding to parts of eastern India through Friday.

Areas south of Visakhapatnam were largely spared any flooding this week as the heaviest rain from the depression remained offshore.

The depression will continue to track northeast into Friday moving very close to or making landfall along the coast of Odisha.

As the low continues to track northeast, heavy rain will fall across northeast Andhra Pradesh, Odisha and West Bengal into Friday.

Total rainfall of 100-200 mm (4-8 inches) with local amounts over 300 mm (12 inches) are expected.

Locations at risk include Puri and Kolkata with the heaviest rainfall expected from Srikakulam to Puri and Ratanpur.

This magnitude of rainfall will create widespread flooding and travel shutdowns. There will also be a heightened risk for mudslides.

Despite the risk for the depression to make landfall, widespread damaging winds are not expected. Wind gusts will generally remain below 50 km/h (31 mph) with local gusts reaching 65 km/h (40 mph) along the coast of northern Andhra Pradesh and Odisha.

Rounds of rain will also extend into Bangladesh through Saturday. Total rainfall during this time is expected to average 25-75 mm (1-3 inches) with the heaviest rain expected in southern and western areas.

Meanwhile, much of northern India will continue to endure high levels of pollution and poor air quality as dry and tranquil conditions fail to relieve the current problems.

Delhi and other parts of northern India have had travel disruptions, school closures and an increase in hospital patients over the past week as air quality has deteriorated and pollution levels have reached severe levels.

Northern India endures high levels of pollution each year from the late autumn into spring as largely dry and tranquil weather settles over the region and allows pollution to build up.

Pollutants are only dispersed by strong storm systems that are infrequent during this four- to five-month period which causes prolonged periods of poor air quality.

No significant relief from the current poor air quality is expected across Delhi into next week.
