Mumbai Rains IMD Weather Update: Red Alert in Raigad and Thane, Orange Alert for Pune

The India Meteorological Department (IMD) has issued urgent weather alerts for parts of Maharashtra, including a red alert for Raigad and Thane, and an orange alert for Mumbai and Pune, as monsoon rains intensify over the region. This detailed update will cover rainfall trends, warnings in effect, risks ahead, and safety measures for residents and travelers.

1. Heavy Rains Trigger Red Alert in Raigad and Thane

The IMD has placed Raigad and the ghat regions of Thane under a red alert, signaling the likelihood of extremely heavy rainfall, potentially over 200 mm within 24 hours, over the next day . These districts have already experienced torrential downpours, prompting school closures and emergency measures. River levels—including the Kundalika in Raigad—are rising rapidly, raising flood and landslide risks.

2. Orange Alert: Mumbai and Pune on High Alert

In Mumbai, the IMD has announced an orange alert for heavy to very heavy rainfall . Expect downpours of 70–100 mm, which may cause widespread waterlogging, high tide warnings, and travel disruption, especially in coastal and low-lying areas. Local civic agencies, including the BMC, have issued high tide advisories to prepare drainage infrastructure.

Meanwhile, around Pune and its adjacent ghat areas, an orange alert remains in effect, with moderate to heavy rains forecast . Although Pune city itself is seeing lighter rainfall compared to Raigad and Thane, surrounding hills like Tamhini and Shirgaon are receiving 40–60 mm, and ghat roads could be impacted by landslides or runoff.

3. Ongoing Rainfall Trends and Recent Data

• Mumbai recorded around 95 mm in a 24-hour period; suburbs saw 58 mm (east) and 75 mm (west) . Trains faced delays, and some metro services temporarily halted due to debris and water ingress.
• In Raigad’s hilly zones, intense rain has prompted authorities to close schools and restrict travel. Prolonged monsoon activity has increased landslide risk .
• Pune ghats reported localized showers: Tamhini 56 mm, Shirgaon 40 mm; city dams remain largely unaffected so far .

4. Predicted Impacts: Disruption Across the Board

Mumbai

• Severe waterlogging in low-lying areas and subways
• Train delays on suburban lines, often up to 30 minutes
• Flight disruptions and delays at the airport
• High tide at around 4.2 m complicating drainage

Raigad and Thane

• Heightened risk of landslides in hill zones
• Continued school and travel suspensions until rains ease
• Flooding of rivers and roads in low-lying villages

Pune

• Ghat roads may close, landslide alerts persist
• Possible waterlogging in city zones
• Rising dam levels may affect city water management

5. Safety Advisory and Precautionary Measures

The IMD and local government agencies recommend the following precautions:

1. Avoid non-essential travel, particularly in affected ghat and low-lying regions.
2. Stay updated on local media and IMD alerts for weather changes.
3. Clear drains and take steps to prevent waterlogging in at-risk areas.
4. Have emergency kits, flashlights, first-aid, and backup power ready.
5. Evacuate promptly if advised, especially in flood-prone or unstable terrain.
6. Travelers should expect delays or cancellations and stay in contact with airlines and rail services.
7. Drivers should navigate cautiously through flooded sections; avoid fast-flowing water.

6. Why These Alerts Matter Now

Several factors have intensified monsoon rainfall across Maharashtra:

• A strong monsoon trough and active weather systems over the Arabian Sea persist.
• Repeated low-pressure zones and cyclonic disturbances reinforce heavy rain cycles.
• As a result, Konkan and ghats are facing persistent rainfall, river swelling, and soil instability .

Red and orange alerts play a critical role in ensuring timely district-level preparedness, limiting accidents, and saving lives when weather turns severe.

7. Looking Ahead: What to Expect

• Short-term outlook (next 24–48 hours): Expect extremely heavy rains in Raigad and Thane, continuing heavy rainfall in Mumbai, and intermittent showers in Pune ghats.
• Mid-term outlook: Rain may continue into the week due to ongoing low-pressure activity.
• Relief measures are in progress: BMC teams are clearing drains in Mumbai; Raigad has activated emergency response units; Pune Municipal forecasters are monitoring hill areas.

🔍 Final Summary

• Raigad & Thane: Red alert—high chances of extremely heavy rainfall and landslides.
• Mumbai: Orange alert—heavy rain, waterlogging, travel disruptions, high tides.
• Pune: Orange alert—rain in ghat roads, potential floods, watch for city waterlogging.

Residents and travelers must stay alert and take these warnings seriously. Swift action now can prevent property damage, personal risk, and ensure safety in the upcoming days of intense rainfall.
