New Bay of Bengal Depression Poised to Hit Andhra Coast Around Nov 3

Bay of Bengal systems routinely menace Andhra—most lethally the Nov 1977 ‘Diviseema’ cyclone that killed ~10,000, and more recently Phailin (2013) and Hudhud (2014). Since the 1980s sea-surface temperatures in the Bay have risen ~0.8 °C, a trend that models link to both greenhouse forcing and decadal Indian Ocean Dipole swings, subtly shifting cyclone tracks northward and extending the post-monsoon storm window. The current depression’s projected moderate intensity echoes Cyclone Helen (2013), not the Category-4 Arnab that just drenched north India; nonetheless, dense coastal settlement and fragile power grids mean even a ‘weak’ landfall can cause outsized disruption. On a 100-year horizon, this episode is another data point in a statistical uptick of late-season Bay storms under warming oceans and recurrent El Niños—raising the stakes for India’s early-warning infrastructure, urban drainage planning and the political economy of coastal agriculture more than for the one-day headlines about whether Delhi skies are cloudy.
