IMD issues yellow alert of thunderstorm across Jharkhand 

PINAKI MAJUMDAR

Jamshedpur, June 11: The Ranchi Meteorological Centre has issued a yellow alert for the next three days, warning of thunderstorms and lightning accompanied by gusty winds reaching speeds of 40–50 kmph.

These weather conditions are expected to impact isolated areas across the state, signalling the active onset of monsoon dynamics.

An upper air cyclonic circulation has formed over north Chhattisgarh and its adjoining areas at around 0.9 Km above mean sea level.

Another cyclonic circulation—initially located over the northwest Bay of Bengal—has shifted inland and is now centred over north Odisha and surrounding regions.

This system extends vertically between 1.5 km and 5.8 Km above mean sea level, tilting southwards with height, a classic indicator of active monsoon behaviour.

Monsoon Update

The Northern Limit of Monsoon (NLM) has continued to advance and currently passes through: 17.0°N/55°E → 17.5°N/60°E → 18°N/65°E → 18.5°N/70°E → Mumbai → Ahilyanagar → Adilabad → Bhawanipatna → Puri → Sandhead Island → 23.5°N/89.5°E → Balurghat → 30°N/85°E.

This trajectory signals that monsoon winds are steadily moving northward, poised to bring more widespread rainfall in the coming days.
