A wide expanse of the country is heading into a prolonged stretch of volatile weather, bringing widespread showers and turbulent atmospheric conditions from northern plains down to southern peninsulas. Even though cyclone Arnab has weakened into a basic low-pressure pocket, atmospheric stability remains distant. An emerging tropical disturbance churning over the seas is set to sustain heavy downpours, intense thunder, lightning strikes, and gusty winds for the next five to six days. Meteorological officials have cautioned that gusts could sweep between forty and sixty kilometers per hour in vulnerable zones, creating disruptions across daily routines.
Developing Marine System and Converging Winds
A well-defined low-pressure zone hovering above the South Andaman Sea continues its west-northwestward track. Around October 31, this specific marine system is heavily favored to intensify into a depression over southeast sectors of the Bay of Bengal and adjacent pockets of the Andaman and Nicobar Islands. From there, steering winds will guide the intensifying system further west-northwest toward the coastline of Andhra Pradesh across the ensuing forty-eight hours. Coastal districts of peninsular India are bracing for deteriorating maritime conditions, with waters off Andhra Pradesh turning rough particularly between November 1 and November 4.
This development follows the dissolution of cyclone Arnab, which by October 29 had degraded into a low-pressure area over central Chhattisgarh and neighboring Odisha terrains. However, several other synoptic features are simultaneously active across the mainland. A cyclonic circulation is presently rotating over northern Punjab. Meanwhile, an atmospheric trough extends from Uttar Pradesh through northern Chhattisgarh into the low-pressure cluster over eastern Madhya Pradesh. A parallel trough cuts from the east-central Arabian Sea through coastal Maharashtra into the Chhattisgarh low. Adding to this mix are active cyclonic circulations positioned over southern Gujarat as well as Assam, producing widespread convergence across the subcontinent.
Widespread Rains Across Eastern Terraces
Eastern territories are slated to bear significant brunt from these interacting weather features. The Andaman and Nicobar Islands are forecast to witness widespread precipitation on October 31, with Sub-Himalayan West Bengal and Sikkim concurrently seeing substantial showers. Vast stretches of Gangetic West Bengal, Bihar, and Jharkhand face an extended spell of cloudiness and intermittent downpours anticipated to stretch from October 31 all the way through November 5. Officials have cautioned that districts across Bihar, Jharkhand, Gangetic West Bengal, and Sikkim must prepare for heavy falls accompanied by surface gusts traveling at thirty to forty kilometers per hour.
Odisha is projected to experience renewed shower activity beginning on November 1, with recurrent rainfall spells scheduled around October 31 as well as from November 2 to November 5. Heavy downpours are specifically likely to strike isolated pockets of Odisha on November 2. The combination of persistent overcast skies and high humidity will keep conditions damp across the entire eastern belt throughout the beginning of November.
Western Disturbance Drives Northern Weather Shift
Across northwestern belts, a western disturbance working in tandem with lower-level circulations is transforming conditions. In Uttarakhand, widespread showers, dangerous lightning, and wind bursts between thirty and forty kilometers per hour are expected on October 31, with isolated heavy downpours likely across hillside zones. The state faces an unsettled pattern lasting from October 31 to November 2. Concurrently, lighter to moderate precipitation will impact high-altitude sectors across Himachal Pradesh, Jammu and Kashmir, Ladakh, Gilgit-Baltistan, and Muzaffarabad through November 2.
Down in the plains, rain is anticipated to reach Delhi, Haryana, and Chandigarh around November 2. These regions alongside Punjab are placed on watch for thunderstorm activity, lightning, and squally gusts blowing at forty to fifty kilometers per hour. Scattered raindrops could fall over western Rajasthan and Punjab, while eastern Rajasthan and western Uttar Pradesh might register showers on October 31. Eastern Uttar Pradesh is set for an extended spell of widespread precipitation spanning October 31 to November 2, bringing potential waterlogging across low-lying locations.
Intense Downpours Slated Across Southern Belts
The southern peninsula will face robust weather activity over the upcoming five days. Scattered light-to-moderate falls are slated for Tamil Nadu, Puducherry, and Karaikal from October 31 through November 5, though the situation will escalate on November 2 and 3 with warnings of heavy rainfall, loud thunder, and lightning strikes. Over in Kerala and Mahe, precipitation is anticipated on October 31, November 3, and November 4, flanking wider widespread spells on November 1, 2, and 5. Severe heavy rainfall is forecast across sections of Kerala and Mahe from November 1 to 3.
Karnataka is also set for comprehensive rainfall coverage. Coastal Karnataka is due for precipitation between October 31 and November 2 before transitioning to widespread rains from November 3 to 5. North Interior Karnataka will encounter wet intervals from October 31 to November 2 and again during November 4 and 5. In South Interior Karnataka, showers are slated between October 31 and November 1, resuming steadily from November 2 through November 5, cementing a week of extensive wet conditions across the peninsula.
