New Bay of Bengal Low Extends Tropical Disturbance Relay
A new area of low air pressure has formed over the Bay of Bengal.
Low-pressure areas can bring clouds, wind and rain.
Other tropical storms are active farther east near the Pacific and South China Sea.
Their movement may send more weather disturbances toward India.
Tropical Storm Narra is expected to remain near Vietnam until Wednesday.
The monsoon winds can help these disturbances grow after they reach the Bay.
The India Meteorological Department expects heavy rain in many parts of India.
Odisha, northeastern states, central India and parts of southern and western India are among the areas named in the forecast.
Some places could receive very heavy rain on isolated occasions.
A new low-pressure area formed over the north-west Bay of Bengal on August 23, 2026.
Typhoon Saudel, Tropical Storm Narra and Tropical Depression 19 are active across the western Pacific and South China Sea.
Narra may help send additional atmospheric disturbances toward the Bay through the coming week.
The monsoon trough runs across northern and central India through the new Bay system.
The India Meteorological Department forecasts prolonged heavy or very heavy rain across several regions over six days.
