After one of the driest Augusts in over a century, India's monsoon reasserted itself in early September, as the Meteorological Department issued sweeping rainfall warnings across more than a dozen states. From the coasts of Kerala and Andhra Pradesh to the river valleys of West Bengal and the plateaus of central India, a system long in retreat was returning with force. The warnings — some elevated to orange alert — reminded a parched subcontinent that nature's rhythms, though delayed, are rarely abandoned.
IMD Issues Very Heavy Rainfall Warnings Across Multiple States Through Sept 8
The monsoon's dormancy had ended, but the damage from August was already done.
Mark
Why does August's rainfall record matter so much? It's one month.
Mimi
Because August is the heart of the monsoon season in India. When it fails that badly—the worst in 122 years—it means crops don't get water, reservoirs stay low, and the entire agricultural cycle is thrown off. One bad month can ripple through the whole year.
Luke
But the forecast is for September to be normal, right? So the damage from August is already done. These September rains won't undo that.
Mark
So the orange alert in Kerala—what does that actually mean for people living there?
Mimi
Orange alert means heavy rainfall is expected and there's real risk of flooding, landslides, and disruption. It's not the highest alert level, but it's serious enough that people should be prepared and authorities should be on standby.
Luke
The source says "orange alert in Pathanamthitta and Idukki districts." Those are specific places. But we don't know how many people live there or what the actual impact will be. The warning is issued; the outcome is still unknown.
Mark
The cyclonic circulation over West Bengal—is that the same as a cyclone?
Mimi
No. It's a weather pattern that could develop into a low-pressure system. The IMD said it's "likely to intensify," but that's a forecast, not a certainty. It means conditions are favorable for heavier rain, but the exact track and intensity won't be known until it develops.
Luke
Right. And the source doesn't give us any numbers on expected rainfall amounts or any historical comparison for what these warnings typically mean in terms of actual precipitation. We know it's coming; we don't know how much.
Mark
Is this recovery from August enough to save the season?
Mimi
That depends on what happens in the rest of September and October. The monsoon doesn't end in September. But if the rains hold at normal levels through the season, yes, it could offset the August deficit.
Luke
Could. The source says September is expected to be normal. That's a forecast. We won't know if it actually happens until it does.
O Pulso
- August 2023 delivered India's lowest monsoon rainfall since 1901, leaving vast stretches of central and southern India critically dry after a 122-year record deficiency.
- On September 4, the IMD issued a cascade of heavy rainfall warnings stretching from Kerala and Andhra Pradesh to West Bengal and Madhya Pradesh, with orange alerts signaling serious risk in Pathanamthitta and Idukki districts.
- A cyclonic circulation forming over West Bengal threatened to intensify into a low-pressure system, adding an unpredictable edge to the monsoon's return across Gangetic plains.
- Andhra Pradesh, Telangana, Odisha, and Kerala braced for four to five consecutive days of heavy to very heavy rainfall, lightning, and thunderstorms through September 8.
- IMD projected September rainfall would normalize at 91–109% of the long-period average, offering cautious hope that the season's deficit could be partially recovered.
After one of the driest Augusts in over a century, India's monsoon reasserted itself in early September, as the Meteorological Department issued sweeping rainfall warnings across more than a dozen states. From the coasts of Kerala and Andhra Pradesh to the river valleys of West Bengal and the plateaus of central India, a system long in retreat was returning with force. The warnings — some elevated to orange alert — reminded a parched subcontinent that nature's rhythms, though delayed, are rarely abandoned.
On September 4, India's Meteorological Department signaled a dramatic meteorological reversal, issuing heavy rainfall warnings across much of the country after one of the driest Augusts in recorded history. Very heavy rains were forecast for September 5 in Odisha, coastal Andhra Pradesh, Telangana, Kerala, and Mahe, with an orange alert — indicating conditions serious enough for heightened caution — issued specifically for Kerala's Pathanamthitta and Idukki districts.
The warnings extended through September 8 and covered an extraordinary geographic sweep. West Bengal faced a forming cyclonic circulation that officials warned could deepen into a low-pressure system, bringing heavy rain to the Gangetic region. Andhra Pradesh prepared for four days of heavy to very heavy rainfall with lightning and thunderstorms across its coastal and interior zones. Central India — including Vidarbha, Chhattisgarh, and Madhya Pradesh — as well as Konkan, Goa, and the Andaman and Nicobar Islands were all within the warning zone.
The reversal followed a historic shock: August's monsoon rainfall was the lowest since 1901, a 122-year deficiency that had gripped central and south peninsular India alike. IMD Director General Mrutyunjay Mohapatra had announced on August 31 that a revival was expected, and projected September would deliver normal rainfall — between 91 and 109 percent of the long-period average of 167.9 millimeters — offering the possibility that the season might yet recover its balance.
For the national capital, the outlook remained modest, with only light rain possible overnight. But across the broader landscape, from Kerala's rain-soaked hills to the swollen rivers of West Bengal, the monsoon's long dormancy appeared to be ending — bringing with it both relief and the urgent question of how much the land could absorb.
The India Meteorological Department issued a cascade of rainfall warnings across the country on September 4, signaling a dramatic shift after one of the driest Augusts in recorded history. Very heavy rains were forecast for September 5 in Odisha, coastal Andhra Pradesh, Telangana, Kerala, and Mahe—with an orange alert specifically issued for Pathanamthitta and Idukki districts in Kerala, indicating conditions serious enough to warrant heightened caution.
The warnings extended through September 8 and painted a picture of a monsoon system reasserting itself across much of India. In Kerala, moderate rainfall was expected to persist for five days straight, with isolated heavy downpours likely between September 4 and 8. West Bengal faced its own threat from a cyclonic circulation forming over the region, which meteorological officials said could intensify into a low-pressure system, bringing heavy rain to Gangetic West Bengal through Wednesday morning. Andhra Pradesh braced for four days of heavy to very heavy rainfall accompanied by lightning and thunderstorms, particularly across North Coastal AP, South Coastal AP, Rayalaseema, and Yanam from Monday through Wednesday.
The geographic scope of the alert was sweeping. East India would see isolated heavy rainfall over Gangetic West Bengal on September 4 and 5, Odisha from the 4th through the 7th, and the Andaman and Nicobar Islands through September 8. South India faced similar conditions: isolated heavy rainfall very likely over coastal Andhra Pradesh and Yanam, Telangana, Tamil Nadu, Puducherry and Karaikal, and Kerala and Mahe during the same window. Central India—including Vidarbha, Chhattisgarh, and Madhya Pradesh—was forecast to receive isolated heavy rainfall from September 4 through 8. West India's Marathwada region, Konkan, Goa, and Maharashtra were also in the warning zone. Even the northeast and northwest would see heavy rainfall by September 7 and 8.
This reversal came after August delivered a meteorological shock. The monsoon rainfall that month was the lowest recorded in 122 years—since 1901—a historic deficiency that extended across Central India and South Peninsular India alike. On August 31, IMD Director General Mrutyunjay Mohapatra had announced that the Southwest Monsoon was expected to revive over the weekend, bringing relief to parched regions. He projected that September would see normal rainfall in the range of 91 to 109 percent of the long-period average of 167.9 millimeters, suggesting the month could help restore what August had taken away.
In the national capital, the forecast was more modest: generally cloudy skies on Tuesday with only the possibility of very light rain at night. But across the broader landscape—from the coasts of Kerala and Andhra Pradesh to the interior plateaus of Madhya Pradesh and the river valleys of West Bengal—the meteorological department was signaling that the monsoon's dormancy had ended. The warnings represented both a return to normal seasonal patterns and a test of how quickly saturated ground and swollen rivers could absorb what was coming.
