Heavy Rainfall Forecast for South India Over the Next Seven Days

Thiruvananthapuram: The US Climate Prediction Center has indicated heightened activity in the Bay of Bengal and the Arabian Sea. Typically, prior to the arrival of the Southwest Monsoon, activity intensifies in the northern reaches of the Indian Ocean. Consequently, changes are currently unfolding across India's three maritime regions that could lead to heavy rainfall accompanied by storms in the near future.

During the month of May, low-pressure areas and depressions frequently form over the ocean, which subsequently evolve into cyclones. Generally, such phenomena occur every 30 to 60 days and play a pivotal role in facilitating the onset of the monsoon. A similar scenario is now beginning to take shape.

Between May 13 and May 19, a low-pressure area or depression is likely to form over the Bay of Bengal and the Arabian Sea, raising the probability of heavy rainfall—potentially accompanied by cyclonic storms—in several adjoining regions. According to the Meteorological Department, a spell of rainfall has already commenced in South Interior Karnataka, while Tamil Nadu, Puducherry & Karaikal, as well as Kerala & Mahe, are likely to experience heavy rainfall over the next seven days.

Furthermore, Lakshadweep, Interior Karnataka, Coastal Andhra Pradesh, Yanam, Rayalaseema, Telangana, and Coastal Karnataka are expected to witness rainfall accompanied by strong winds or thunderstorms with lightning. This will increase the moisture content in agricultural soil, thereby aiding farmers in the cultivation of Kharif crops.
