Kerala Braces for Heavy Rainfall as Yellow Alert Issued Until May 28

Weather Forecast for Kerala

Despite delays, Kerala is expected to experience significant rainfall, prompting the weather department to issue a 'Yellow Alert' across the state until May 28. According to the Indian Meteorological Department (IMD), light to moderate rain accompanied by thunderstorms and strong winds is predicted from May 26 to May 29 in Kerala, Mahe, and the Lakshadweep Islands. The department also noted that conditions remain favorable for the southwest monsoon to advance over parts of the Arabian Sea, Comorin region, Bay of Bengal, and Andaman Sea.

Monsoon Delays and Predictions

The arrival of the southwest monsoon in India, initially expected on May 26, has been delayed. This postponement is attributed to a cyclonic system forming in the Bay of Bengal, which is disrupting the necessary broad winds for the monsoon. The IMD has updated its forecast, indicating that monsoon rains could reach Kerala between June 2 and June 4.

Criteria for Monsoon Declaration

The official announcement of the monsoon in Kerala occurs only when at least 60% of the rain gauges in the Kerala and Lakshadweep weather centers record a minimum rainfall of 2.5 mm. Currently, the westerly winds in northern Kerala are weak, and meteorologists suggest that it may take another day or two for these winds to strengthen sufficiently for the monsoon's arrival. However, experts believe that the prevailing atmospheric conditions are largely favorable for the monsoon's onset, with ongoing drizzle and thunderstorms indicating early signs of seasonal change.

Yellow Alert Details

On May 26, a Yellow Alert was issued for Thiruvananthapuram, Kollam, Alappuzha, and Ernakulam districts. Warnings will continue for Thiruvananthapuram, Kollam, and Alappuzha on May 27, while the alert will expand to include Thiruvananthapuram, Kollam, Pathanamthitta, Alappuzha, Kottayam, Ernakulam, and Idukki on May 28. The IMD has cautioned that heavy rainfall could lead to flooding on major roads, disrupting traffic.

Flood and Wind Warnings

There is also a risk of flooding in low-lying areas and near riverbanks. Authorities have warned that strong winds could uproot trees and damage power supply systems, potentially causing partial damage to homes and huts. The department has issued alerts for landslides and soil erosion in vulnerable areas, advising people to avoid unnecessary travel and seek safe shelter.
