IMD predicts heavy rain in 6 districts, Yanam today

What Happened

The India Meteorological Department (IMD) reported that a low pressure area formed over the northwest Bay of Bengal and adjoining the coasts of West Bengal and north Odisha. It is expected to move northwestwards and concentrate into a depression within the next 12 hours. The system was first noted at 5:30 a.m., intensified to a well-marked low pressure area by 2:30 p.m., and remained in that state at 5:30 p.m. according to the Cyclone Warning Centre, Visakhapatnam. Winds are forecast to reach 40-50 kmph with gusts up to 60 kmph over the northwest and west-central Bay of Bengal and along the north Andhra Pradesh coast through Tuesday. The sea is expected to stay rough with possible surge waves. The Andhra Pradesh State Disaster Management Authority (APSDMA) has issued advisories reflecting these conditions and has urged fishermen to avoid sea ventures and return if already at sea.

IMD forecast rain: heavy rainfall at isolated locations is expected over Srikakulam, Vizianagaram, Parvathipuram Manyam, Anakapalli, Alluri Sitharama Raju districts, and Yanam within the next 24 hours. For Monday, thunderstorms with lightning and light to moderate rain are likely at isolated places in several districts including Srikakulam, Vizianagaram, Visakhapatnam, Nellore and Tirupati, with a broader light rain chance in many north coastal Andhra Pradesh districts. On Tuesday, light to moderate rain is anticipated across the north coastal Andhra Pradesh region.

Additional coastal warnings include strong surface winds of 40-50 kmph at isolated spots across coastal Andhra Pradesh, Yanam, and Rayalaseema over the next two days. The advisory against venturing into the sea will be extended from the north coast to the south coastal Andhra Pradesh coast from Tuesday. Sea conditions are forecast to be rough to very rough off the coasts of West Bengal, Odisha, and north Andhra Pradesh through Tuesday. Effects such as swell surges and ocean current alerts have been issued for multiple districts, with harbour and marine operations asked to exercise caution.

Temperature and humidity readings from the Regional Meteorological Centre, Amaravati, show Tirupati recording the state's highest maximum temperature at 38.5°C, 3.5°C above normal, followed by Kavali at 38.3°C and Bapatla at 37.9°C. Among 21 monitoring stations, Tuni recorded rainfall at 8 mm. Relative humidity peaked at Visakhapatnam, at 80%.

Why It Matters

The forecast signals potential disruption to coastal activities and local mobility across several districts in north coastal Andhra Pradesh, with implications for fishing, small-scale agriculture, and public safety. The combination of a developing low pressure system, gusty winds, and rough sea conditions raises the risk of wind damage and water-related hazards in the affected areas, alongside the possibility of localized heavy rainfall causing flooding in vulnerable zones.

Background

The IMD’s bulletin describes a low pressure system originating in the northwest Bay of Bengal, a region historically prone to cyclonic activity during certain seasons. The progression toward a depression, aided by an upper air cyclonic circulation, is a common phase preceding stronger storm systems, which typically bring heavy rainfall and strong winds to adjacent landmasses. Local disaster management authorities have issued precautionary advisories to mitigate risk to residents and maritime operations.
