Mumbai and its surrounding regions are once again on high alert as the India Meteorological Department (IMD) forecasts intense rainfall and the possibility of extreme weather conditions over the coming days. An orange alert has been issued for Mumbai and Thane for Friday, while Raigad is under a red alert — indicating extremely heavy rain, according to The Free Press Journal.

The Brihanmumbai Municipal Corporation has also warned of high tides today.

What To Expect In Mumbai?

The city's 24-hour weather forecast predicts mostly cloudy skies with moderate rain, and a high chance of heavy to very heavy showers in some areas, particularly late at night or early morning. 

A weather bulletin for Friday by the IMD read: "Generally cloudy sky with possibility of heavy to very heavy rainfall in the city and suburbs. Maximum & Minimum temperatures likely to be around 30 degrees Celsius and 23 degrees Celsius."

The continuous spell of rain has also resulted in waterlogging and, consequently, commuting woes in Maharashtra.

The IMD's latest bulletin, issued earlier this week, had already warned of a surge in rainfall across Maharashtra. Several districts, including Ratnagiri, Sindhudurg, the ghat areas of Pune, Satara and Kolhapur, and large parts of Vidarbha, have been placed under similar orange and red alerts.

In the last 24 hours, several neighbourhoods reported significant downpours: Mankhurd recorded 28 mm, Nariman Point 26 mm, CSMT 21 mm, and Mulund 21 mm. Other areas like Sewri, Chakala, Chembur and Aarey Road also saw substantial rain.

Despite the steady showers, there's been no major waterlogging so far. However, the IMD has warned that isolated areas in Mumbai, Thane and Palghar may receive moderate spells of rain in the next few hours, which could lead to water accumulation in low-lying areas if the rain persists.

Reservoir Levels Rise To 87%

There's one upside to the wet spell: Mumbai's water supply is looking far more secure. Thanks to heavy rainfall in the catchment areas, the city's seven reservoirs are now 87% full — a massive jump from 58% on the same day last year, and just 53% in 2023.

Two of these dams — Modak Sagar and Tansa — have begun overflowing. Earlier this month, the Middle Vaitarna dam had two of its gates opened, and water is now being released from Upper Vaitarna as well.

High Tides Expected Through Weekends

Meanwhile, the Brihanmumbai Municipal Corporation (BMC) has flagged another risk: high tides. Over the next three days, Mumbai is expected to see tidal waves rising above 4.5 metres, peaking at 4.67 metres on Saturday, July 26, around 1:20 pm.

The expected tide heights for the next few days are:

• July 25: 4.66 metres at 12:40 PM
• July 26: 4.67 metres at 1:20 PM
• July 27: 4.60 metres at 1:56 PM

The BMC has advised residents to steer clear of beaches and coastal areas during high tide hours, especially as heavy rain coinciding with high tides increases the flood risk. The BMC further warned of staying away from the shoreline, especially around noon as the high tide is expected to rise to 4.66 metres at 12.40 PM.

🌊Today, 25th July 2025, a high tide of 4.66 meters at 12.40 PM.

⚠ Please avoid going near the seashore during high tide.

🙏 Kindly follow the instructions issued by the Brihanmumbai Municipal Corporation.

On Thursday, rainfall intensity picked up significantly across several parts of suburban Mumbai — including Andheri, Borivali, Malad, Dahisar, Kandivali, Goregaon, Bandra and Vile Parle. The Andheri subway was temporarily closed to traffic due to rising water levels.

Weather Outlook

Looking ahead, the IMD expects heavy rain to continue through Friday and Saturday, with some relief likely from Sunday onward. From July 27, showers are expected to ease, and no weather warnings have been issued beyond that date.

But until then, Mumbai will need to remain cautious. The combination of saturated ground, rising reservoirs, and high tides could prove dangerous. Authorities are urging people to stay updated on advisories, avoid unnecessary travel during peak rainfall or tide hours, and take basic precautions — especially in flood-prone neighbourhoods.

The rain may be a blessing for the city's water supply, but for now, Mumbai's monsoon continues to demand patience — and preparation.
