Cyclonic systems, active monsoon patterns to fuel heavy showers in Jharkhand

Jamshedpur: Jharkhand is set to witness a prolonged spell of intense rainfall, thunderstorms, and gusty winds over the next four days, as multiple weather systems align to create unstable atmospheric conditions across the state.

According to the latest meteorological bulletin, issued this evening, several districts — particularly in the south-western and north-central regions — are expected to bear the brunt of the adverse weather beginning June 16 and continuing through June 19.

The India Meteorological Department (IMD) has issued a cautionary alert, citing heavy to very heavy rainfall accompanied by lightning, thunderstorms, and gusty winds reaching speeds of 40–50 kmph at isolated locations across the state. Authorities have advised residents, especially farmers, travelers, and those living in low-lying or vulnerable areas, to remain vigilant and take precautionary measures.

June 18 (Tuesday):  The rain belt is expected to shift northward, with very heavy rainfall predicted in north-central and north-eastern districts, including Hazaribagh, Chatra, Giridih, and Deoghar. Simultaneously, north-western areas such as Palamu and Garhwa could also witness heavy downpours, raising concerns about waterlogging and local flooding.

June 19 (Wednesday): The final day of the forecasted spell will see continued rainfall activity, particularly over north-central and north-eastern parts of the state. Thunderstorms with gusty winds will likely continue to occur at scattered locations, sustaining the risk of disruption to power and transportation services.

The IMD has attributed this intense wet spell to a combination of multiple synoptic features influencing the eastern Indian subcontinent: A cyclonic circulation currently hovering over the northwest Bay of Bengal is actively pumping moisture into the region, significantly enhancing rainfall activity across eastern India, including Jharkhand.

A trough line is extending from East Madhya Pradesh to Bangladesh, traversing across Jharkhand, which is causing moisture incursion and atmospheric instability conducive to thunderstorm development.

An upper-air cyclonic circulation is persisting over East Uttar Pradesh, which may further aid the formation of storm systems in adjoining areas.

Additionally, the Northern Limit of the Southwest Monsoon (NLM) has advanced and is currently passing through parts of Maharashtra, Odisha, West Bengal, and eastern Nepal. Conditions are reportedly favourable for its further progression into Gujarat, Vidarbha, Chhattisgarh, Odisha, West Bengal, Jharkhand, Bihar, and East Uttar Pradesh over the next 72 hours.

The meteorological department has urged district administrations, disaster management teams, and rural development bodies to remain on high alert. Local residents are advised to avoid unnecessary travel, secure loose objects, and stay indoors during thunderstorm activity.
