Pune’s monsoon always shapes life in the city. Lanes turn green, lakes brim, and for weeks the city moves with the weather. But this season the rains have been different heavier in some places, sudden in others, and sometimes dangerous. If you live in Pune or nearby talukas and ghats, this guide will give you the facts, explain the causes in plain language, and tell you what to do before, during, and after heavy rain.
Quick Snapshot — The Most Important Facts
· Haveli taluka recorded about 180 mm of rain in roughly 24 hours during a recent intense spell.
· Ghats and hill pockets saw extreme 24-hour totals: Tamhini ~575 mm, Lonavala ~418 mm in a major episode in August.
· Several key reservoirs near Pune reached near full storage and started controlled releases to protect dam safety.
· IMD issued graded alerts — yellow, orange, and in nearby districts even red — prompting warnings for residents and agencies to act.
Why These Heavy Rains Are a Big Deal?
Heavy rain matters because it can overwhelm systems designed for everyday weather. Here’s how that happens in practical terms:
· Drainage fails fast. Paved roads and clogged drains make water sit on streets. Even a few hours of heavy rain can block major junctions.
· Homes in low areas flood. Many neighborhoods were built on older lake beds or beside nullahs (natural drains). When discharge increases and drains are blocked, water reaches ground floors quickly.
· Dams must release water. To protect a dam’s walls, authorities open gates when reservoirs fill. That raises river levels downstream. If residents are not warned or roads are already flooded, the risk increases.
· Ghats face landslides. The Western Ghats get very heavy rain. When soil becomes saturated, slopes slip and roads or villages can be cut off.
This combination heavy bursts, urban pressure, full dams, and steep terrain explains why some rain events feel catastrophic even if they last only a day.
What Actually Happened? A Short Timeline of Recent Events:
A very wet morning in Haveli. Automatic weather stations recorded Haveli as the district’s highest point that day, with about 180 mm by early morning. Nearby stations Lohegaon, Chinchwad, Shivajinagar also saw heavy amounts, which caused waterlogging and local advisories.
Tamhini and Lonavala’s extremes. In one major episode, parts of the ghats recorded hundreds of millimeters in 24 hours Tamhini about 575 mm and Lonavala 418 mm. These readings triggered landslide warnings and local closures in ghat stretches.
Reservoirs near capacity. By early September several Khadakwasla circle dams had reached high storage and began controlled releases. The municipal pages and local agencies posted discharge figures and cautions for downstream residents.
IMD alerts and traffic impacts. With a low-pressure area and favourable conditions for heavy showers, IMD issued yellow and orange alerts for Pune and ghats; nearby coastal districts faced red warnings at times. These alerts were used to trigger public advisories and traffic management.
A Simple Explanation of the Causes:
You do not need meteorology training to understand why some days pour and others barely drizzle. Here are the main drivers, in plain language:
Monsoon mechanics. The southwest monsoon pushes moist air over Maharashtra. When the atmosphere supports it, that moisture condenses into heavy rain. Low pressure areas act like a magnet for moisture, making a place get a lot of rain in a short time.
Western Ghats uplift. Moist winds hit the ghats, get pushed up, cool down, and rain out. That is why ghat passes like Tamhini and Lonavala often record much higher totals than the plains.
Urbanization and drainage. Roads, parking lots, and new construction reduce ground absorption. If drains are choked with garbage, water cannot escape. So an inch of rain in a paved area causes more surface pooling than the same rain in a grassy field.
Changing climate patterns. Studies and weather tracking show a trend toward fewer rainy days but stronger bursts when it does rain. That increases the frequency of flash flooding. (This is a trend seen across many parts of India and the world.)
Who Is Most at Risk?
· People living in low-lying areas, old lake beds, or next to blocked nullahs.
· Residents downstream of dams and along the Mutha and other rivers when controlled releases begin.
· Communities and commuters on ghat roads slips and closures can isolate villages or cut main routes.
· Informal settlements and ground floor households with limited resources to move belongings.
Practical Safety Checklist: What to Do Before, During, and After Heavy Rain!
Easy actions prevent a lot of suffering. Share this checklist with family and neighbors.
Before the heavy rain season:
1. Clear drains near your house. Push garbage away from gullies and report major blockages to the ward office.
2. Make a small emergency kit: torch, power bank, portable radio, medicines, some drinking water, copies of important documents in a waterproof folder.
3. Know your evacuation route and nearest higher ground. Identify a family contact outside the flood zone.
When alerts are issued:
1. Check IMD and local authority alerts. If you see yellow/orange/red alerts, plan, do not panic.
2. Avoid travel through low underpasses or streets with moving water. Driving through deep water is one of the most dangerous choices during floods.
3. Move valuables, important documents, and electronics to higher shelves.
During heavy rainfall:
1. Stay indoors if possible. If outdoors, avoid wading through floodwater it hides open drains, live wires, and contamination.
2. Keep family members informed. If you live downstream of a dam, pay attention to official dam discharge announcements.
After the rain:
1. Do not drink municipal water until authorities confirm it is safe. Boil or use purified water if in doubt.
2. Clean and disinfect areas where floodwater entered. Standing water can spread infection and breed mosquitoes.
3. If you suspect landslide danger near your home, do not return until officials declare the area safe.
What Local Authorities Are Doing and Where They Can Do Better
What’s working:
· Graded warnings. IMD issues yellow, orange, and red alerts that help municipal teams plan road closures and rescue efforts.
· Dam management. Authorities monitor reservoir levels and do controlled releases to prevent dam failure. Notices about discharge volumes have been published by civic bodies.
Where improvements are needed:
· Localized nowcasting. People need ward level, short term forecasts so a neighbourhood gets warned 1–3 hours before flooding.
· Routine drain maintenance. Regular cleaning and desilting before monsoon peaks can dramatically reduce waterlogging.
· Strict land use enforcement. No more building in floodplains and protection of natural lakes and wetlands would ease flooding long term.
· Public education. Simple campaigns about what to do during dam releases, how to avoid waterborne disease, and how to prepare homes would save lives.
Case Study: How One Heavy Morning Flooded Haveli?
Haveli’s roughly 180 mm in a short window overwhelmed local drains. Roads flooded, some low homes saw water come in, and warnings were issued. The event highlights three important points:
1. Short, intense rain overwhelms systems faster than slow, steady rain.
2. Local variation matters: one part of Pune can flood while another stays relatively dry.
3. Timely local alerts and community readiness matter more than a general city warning.
Health Risks After Floods — Short and Real:
· Mosquito borne diseases. Mosquito breeding increases in standing water. Protect against dengue and malaria.
· Contaminated water. Floodwater carries sewage and bacteria. Boil or treat water for drinking.
· Injuries and infections. Cuts or wounds exposed to dirty water can get infected. Seek medical attention early.
FAQ
Q: Is Pune getting more rain than before?
A: Some recent months and ghat pockets have seen extremely high 24-hour totals. Overall monsoon patterns are more variable, with signs of intense short bursts in some years.
Q: Are dams safe when they release water?
A: Dams are monitored and authorities perform controlled releases to protect the structure. Downstream residents must follow official advisories and avoid riverbanks during releases.
Q: What is the fastest way to get official alerts?
A: Follow IMD updates and the Pune district or municipal corporation social channels. Local news outlets also republish alerts and dam discharge notices.
