IMD Forecasts Heavy Rainfall for Andaman and Nicobar, Thunderstorms in Rajasthan

The India Meteorological Department has issued an updated weather bulletin forecasting intense rainfall across the Andaman and Nicobar Islands alongside widespread thunderstorm activity over parts of Rajasthan. Meteorologists noted that two distinct atmospheric systems are simultaneously driving these contrasting weather developments across the country. While the southern maritime territory prepares for sustained tropical downpours, the northwestern desert state is experiencing sudden shifts in wind and convective instability.

According to the meteorological agency, fairly widespread to widespread rainfall is slated to persist across the Andaman and Nicobar archipelago over the coming days. The wet spell is expected to bring isolated heavy showers, frequent lightning discharges, and gusty surface winds clocking between 30 and 50 kilometers per hour. Forecasters indicated that localized precipitation totals could escalate quickly as convective cloud bands pass over the islands.

The heightened weather activity across the island territory is being steered by a well-marked low-pressure area over the Southeast Bay of Bengal and the adjoining Andaman Sea. Weather officials stated that the cyclonic circulation associated with this system continues to pull abundant moisture from the warm ocean waters. Meteorologists are monitoring the system closely, as regional conditions remain conducive to further consolidation and atmospheric intensification.

In light of the deteriorating ocean conditions, the weather bureau has issued strict advisories warning fishermen and maritime operators against venturing into deep waters. Rough to very rough seas accompanied by squally winds are anticipated to prevail along the coastal stretches and the Andaman Sea. Authorities stressed that small sea-going vessels and coastal transport services should exercise extreme caution or suspend operations until conditions stabilize.

Meanwhile, across northwestern India, the weather department confirmed that several pockets of East and West Rajasthan are encountering abrupt thunderstorms, lightning strikes, and brisk surface winds. Wind speeds across exposed areas are expected to hover between 30 and 40 kilometers per hour, with peak gusts occasionally reaching 50 kilometers per hour. These conditions are generating brief spells of precipitation alongside blowing dust across vulnerable districts.

Atmospheric scientists explained that the convective turbulence over Rajasthan is largely propelled by the influence of an active western disturbance traversing the northern latitudes. The upper-air trough is interacting with moist lower-level air currents, creating the thermal and pressure gradients necessary to trigger afternoon thunderstorms. Forecasters observed that such transitional weather patterns frequently induce rapid micro-scale weather changes across the desert landscape.

The dual weather occurrences present notable operational and safety challenges for both regions. In Rajasthan, high wind gusts and sudden lightning strikes present risks to standing seasonal crops, light structures, and rural electrical distribution lines. Across the Andaman and Nicobar Islands, continuous rainfall threatens low-lying infrastructure, localized drainage networks, and inter-island connectivity.

Local administrations and disaster management units in both jurisdictions have been advised to maintain heightened vigilance. Residents in thunderstorm-prone areas of Rajasthan have been urged to avoid open fields, tall trees, and ungrounded metallic objects during active lightning periods. Simultaneously, emergency personnel in the Andaman Islands are reviewing contingency measures to address potential waterlogging and localized coastal erosion.

Looking ahead, the India Meteorological Department stated that it will maintain round-the-clock tracking of both meteorological systems as they progress. Weather watchers noted that further updates will be issued if the Bay of Bengal low-pressure system organizes into a stronger depression or alters its projected trajectory. In the meantime, citizens and maritime stakeholders are encouraged to rely on official meteorological bulletins for timely safety guidance.
