India’s monsoon is picking up again, and the latest satellite pictures say it all—huge rain clouds stretch over most of the country, and a weather system in the Bay of Bengal is on the move.
On August 13, EUMETSAT and INSAT-3D/3DR satellites caught images showing a massive sheet of clouds running all the way from the Arabian Sea through central India and into the Gangetic plains and the Northeast.
The wildest activity is happening around the northern Bay of Bengal, eastern India, and Bangladesh. You can actually see the super-cold cloud tops from space, which signals really strong thunderstorms building up.
Fascinating monsoon days ahead. The Bay of Bengal is likely to remain hyperactive. Back-to-back low-pressure system genesis is on the cards. This looks like a very good sign for the overall monsoon. A major impact is likely over central, east, and north India.

This new burst of rain all centers on a low-pressure system that showed up over the northern Bay of Bengal, right near the West Bengal-Bangladesh coast. After that, it got stronger and turned into a full depression.
The India Meteorological Department’s take? The system isn’t letting up any time soon. As it heads inland, it’s fueling steady, drenching rain—some of the heaviest downpours are set for West Bengal, Odisha, Jharkhand, and Chhattisgarh.
Parts of the hit areas have already seen more than 21 centimeters (about 8.27 inches) of rain.
Satellite images reveal the scale of the monsoon
Satellite images from August 13 show just how big the monsoon circulation has gotten. Unusually clear too.
You’re not looking at scattered thunderstorms anymore. Cloud bands stretch across huge chunks of the subcontinent instead.
Uttar Pradesh, Bihar, Madhya Pradesh, and parts of northeastern India all have massive cloud formations. Farther east the convection gets even deeper.
Meteorologists pay close attention to cold cloud tops. Infrared satellites pick these up.
Cold tops mean something specific. Thunderstorms have punched up through tons of atmosphere. Upper clouds reach way up into the troposphere where it’s freezing cold.
Deep convection like that produces heavy rain.
Pan India rainfall departure now stands at -12% below normal till 12th August. Daily rainfall in the country continued to stay below normal for 7th day in a row.

The dynamics of India’s monsoon in detail
Southwest monsoon winds pull massive amounts of moisture from the Indian Ocean, Arabian Sea, and Bay of Bengal toward the subcontinent. Now a new depression adds another way to squeeze that moisture together.
Surface air gets pulled toward the low-pressure system. As it piles up, it rises. Cooling and condensing happen. Clouds and rain spread out across huge areas.
Meanwhile, the monsoon trough keeps going strong over India.
When you combine the trough, the Bay of Bengal circulation, and all that tropical moisture, you see why the cloud cover stretches so far beyond the depression’s center. Visible from space, it spreads way out.
Rain ends up hitting places hundreds of kilometers away from where the system actually is.
India’s monsoon has been repeatedly re-energized
The latest development continues a pattern Meteo.Events has been following throughout August.
Earlier this month, Meteo.Events reported how India’s strengthening monsoon was increasing the threat of floods and landslides, as repeated heavy-rain episodes affected large parts of the country.
The latest satellite imagery shows that the atmospheric engine responsible for those rains remains highly active.
Rather than weakening into scattered convection, the monsoon has developed another large, organized cloud shield with a well-defined Bay of Bengal circulation supplying additional moisture.
As the depression moves inland, the center of the rainfall threat will shift westward with it.
That means rainfall may gradually ease in some coastal areas while simultaneously intensifying farther into central India.
For now, the view from space is striking: dense cloud bands cover a large portion of the subcontinent, while deep thunderstorms over eastern India reveal just how much energy and moisture remain available to the monsoon.
