The shift ending a weeks-long dry spell brings active Bay of Bengal low-pressure systems, widespread thunderstorms, and heightened flash flood warnings to hill states.
NEW DELHI — Following weeks of patchy precipitation and a prolonged lull across the plains, the India Meteorological Department (IMD) announced a strong, nationwide revival of the southwest monsoon. Weather systems forming over the Bay of Bengal and Arabian Sea are pulling moisture inland, bringing widespread downpours across northern, eastern, central, and western regions.
The primary catalyst for this shift is the return of the monsoon trough—an elongated low-pressure belt that steers rain-bearing cloud bands across the subcontinent—to its normal position after temporarily drifting north toward the Himalayan foothills.
1. Multiple Weather Systems Fuel Active Monsoon
According to IMD meteorologists, six upper-air cyclonic circulations lined up over Punjab, Uttar Pradesh, Rajasthan, Assam, and the Bay of Bengal are pulling heavy moisture inland.
🌧️ IMD Seven-Day Synopsis (July 20 – July 26):
📍 Monsoon Trough Position ➔ Shifted south from Himalayan foothills to central plains.
🌊 Primary Drivers ➔ Bay of Bengal low-pressure area + Arabian Sea moisture flow.
⚠️ Key Hazard Areas ➔ Himachal Pradesh, Uttarakhand, J&K, Assam & Meghalaya.
While the early July break phase caused rainfall deficits of up to 51% below normal across peninsular and central pockets, the current revival is expected to replenish depleted soil moisture and reservoir levels across northern and eastern farming belts.
2. City-Wise & Regional Forecast Breakdown
The intensity of the wet spell will vary across regions, with Western Himalayan states facing extreme downpours while peninsular India remains comparatively dry.
IMD Regional Warnings & Weather Impacts
| Region / State | IMD Alert Level | Weather Condition & Local Impact |
| Delhi-NCR | Yellow Alert | Cloudy skies, light to moderate rain spells, and gusty winds (up to 50 km/h). Daytime temperatures drop below normal. |
| Himachal Pradesh | Red Alert | Extremely heavy rainfall (>204.4 mm) in Chamba, Kangra, Kullu, Mandi, and Sirmaur. Schools closed due to landslide risks. |
| Uttarakhand & J&K | Orange Alert | Heavy to very heavy downpours; high surface runoff and localized landslips reported in Dehradun and Chamoli. |
| Assam & Meghalaya | Orange / Red Alert | Saturated river basins face fresh flash flood threats. Over 57,000 residents already impacted across seven districts. |
| Central & West India (MP, UP, Gujarat, Konkan) | Yellow / Orange Alert | Active rainfall spells through July 24; Konkan and Goa continue to receive heavy coastal showers. |
Weekly Progression of the Revival
The day-by-day progression of rain systems across India.
Flash Flood Advisory: The IMD has highlighted heightened flash flood risks across steep mountain slopes in Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Sikkim, and Assam. Saturated soil catchments mean even moderate rainfall can trigger rapid surface runoff and river swelling.
