Why 'ঘূর্ণিঝড়' Trended in India on 16–17 September 2026: IMD Low-Pressure Forecast Explained

Bengali readers searching for ঘূর্ণিঝড় in mid-September 2026 wanted to know one thing: whether a cyclone was forming over the Bay of Bengal and whether West Bengal would face heavy rain around Durga Puja. Based on reports published on 16 and 17 September 2026, the answer was that the India Meteorological Department (IMD) had flagged a possible low-pressure system — not a confirmed cyclone — and had not issued any specific West Bengal warning at that time.

What Google Trends India recorded

On 17 September 2026, Google Trends India listed ঘূর্ণিঝড় as a trending search term. The signal showed roughly 2,000 approximate searches and 800% growth over the previous 24 hours (Google Trends India). This metric reflects public interest only; it does not confirm that a cyclone existed.

What the weather reports said

ABP Ananda — 16 September 2026

ABP Ananda reported that a cyclonic circulation could form over the Andaman Sea and adjoining Bay of Bengal around 17 or 18 September, and might later intensify into a low-pressure area. The report cited sea-surface temperatures of about 30–31°C, which are favourable for intensification (ABP Ananda).

Hindustan Times Bangla — 16 September 2026

Hindustan Times Bangla, citing IMD, said a low-pressure area was likely to form over the north Andaman Sea by Saturday, 19 September, and could subsequently move toward south Odisha and north Andhra Pradesh. The report explicitly stated that it was still unclear whether the system would become a cyclone (Hindustan Times Bangla).

TV9 Bangla — 17 September 2026

TV9 Bangla reported on 17 September that although the low-pressure system could strengthen and move toward Odisha and Andhra Pradesh, whether it would turn into a cyclone remained unclear. The same report noted that rainfall in West Bengal could increase in late September (TV9 Bangla).

Cyclone, low pressure, or cyclonic circulation?

Readers often use ঘূর্ণিঝড় loosely, but meteorologists distinguish between stages. A cyclonic circulation is an early, loosely organised rotating system. A low-pressure area is more organised and can bring widespread rain. A cyclone requires further intensification and a closed circulation with defined wind criteria. As of 17 September 2026, IMD had not confirmed any of these stages for the Bay of Bengal system beyond a forecast low pressure, and scientists said the system was still far from the coast.

Source	Date	Key point	Status
ABP Ananda	16 Sep 2026	Cyclonic circulation may form over Andaman Sea/Bay of Bengal around 17–18 Sep	Forecast
Hindustan Times Bangla	16 Sep 2026	IMD expects low pressure over north Andaman Sea by 19 Sep; possible track toward south Odisha/north Andhra	IMD forecast
TV9 Bangla	17 Sep 2026	Unclear if system becomes cyclone; late-Sep rain may increase in West Bengal	Uncertain
IMD (as reported)	17 Sep 2026	No confirmed cyclone or specific West Bengal impact; system distant from coast	Not confirmed

Why this matters for Durga Puja planning

The search spike coincided with the run-up to Durga Puja, when weather anxiety is high. However, none of the September 2026 reports confirmed a cyclone landfall in West Bengal. Anyone reading this in November 2026 should treat the trend as a dated snapshot of public interest in an uncertain forecast, not as an active weather warning. For current conditions, readers should consult IMD bulletins directly.
