A yellow alert is in effect for these cities and surrounding districts, warning of short, intense rain spells and gusty winds. Air travel in Mumbai may face delays due to the unstable weather.

Mumbai and Pune are set for another round of unsettled weather on June 3 and June 4, with the India Meteorological Department (IMD) forecasting thunderstorms, lightning, and light to moderate rainfall across several parts of Maharashtra. Both cities, along with nearby districts like Thane and Palghar, are under a yellow alert, signaling short but intense spells of rain and gusty winds.

IMD's Yellow Alert for Mumbai, Thane, Palghar and Pune

The IMD has issued a yellow alert for Mumbai, Thane, Palghar, and Pune for June 3 and continuing into June 4, warning of unstable weather conditions.

Forecast highlights include:

Thunderstorms with lightning

Light to moderate rainfall

Gusty winds around 30–40 kmph in isolated areas

Sudden weather changes during afternoon and evening hours

Meteorologists say the system is part of a larger pre-monsoon activity belt currently active over Maharashtra.

Pune Weather: Storms, Lightning and Rain Till June 5

Pune is also under a yellow alert from June 3 to June 5, with weather experts predicting thunderstorm activity to persist for several days.

Expected conditions:

Thunderstorms with lightning

Light rain showers in many areas

Gusty winds during late afternoon and evening

Partly cloudy to overcast skies through the period

Weather officials say the system is part of active pre-monsoon convection over central Maharashtra, which often triggers sudden rain bursts in Pune and surrounding regions.

Thane and Palghar Also in Rain Zone

The IMD warning extends beyond the two major cities. Thane and Palghar are expected to receive:

Isolated thunderstorms

Moderate rainfall spells

Strong winds in pockets

These districts are likely to experience similar weather patterns as Mumbai, especially during evening hours when storm activity tends to peak.

Why Weather Is Changing Suddenly in Maharashtra

Meteorologists attribute the current instability to strengthening pre-monsoon systems over the Arabian Sea and inland Maharashtra.

This typically leads to:

Sudden thundercloud formation

Short but intense rain bursts

Lightning activity in urban and semi-urban zones

Such patterns are common in early June, just before the full southwest monsoon arrives in the region.

What to Expect on June 3–4

Across Mumbai–Pune region, the weather will likely stay dynamic:

Morning: cloudy skies, humid conditions

Afternoon: thundercloud development

Evening: thunderstorms with lightning and gusty winds

Night: scattered light rain in pockets
