KSNDMC Issues Seven-Day Report

Extremely heavy rainfall is expected at isolated locations, particularly in the coastal and Malnad districts.

Alerts Across Karnataka

Red Alert: Coastal Karnataka and South Interior Karnataka, including Bengaluru.

Orange Alert: North Interior Karnataka, where heavy rain and strong winds are likely.

The IMD said the rain may be accompanied by thunderstorms, lightning, and gusty surface winds, raising concerns over localised flooding and damage to weak structures.

Advisory for Citizens

Officials have urged residents to stay indoors during heavy spells of rain, keep windows and doors shut, and avoid venturing near waterlogged areas or riverbanks. The IMD also warned of possible traffic disruptions, power outages, and uprooting of trees in certain areas.

Southwest Monsoon Activity

The current spell of rain is part of the Southwest Monsoon, which remains active across Karnataka. The monsoon, lasting from June to September, is marked by seasonal wind reversals that bring moisture-laden winds from the sea to the land, causing heavy downpours across South Asia.

With humidity levels expected to hover around 91%, the rain is set to make conditions damp and uncomfortable despite cooler temperatures. Authorities have advised people to remain alert as more intense showers are forecast over the next three days.
