Heavy Rain Alert for Kerala: Downpours Expected to Intensify During Onam Festivities

Metbeat Weather has released a comprehensive rainfall forecast for Kerala covering the period from Chothi (August 19) through the fourth day of Onam, Chathayam (August 28).

According to the weather model, the initial phase of the festival starting on Chothi will bring relatively light and isolated showers across the state, primarily concentrated in the eastern and northern regions. However, precipitation is forecasted to gain significant strength starting on Pooradam (August 24), leading into a wet festive season.

Key Forecast Highlights:

Chothi (August 19) & Vishakam (August 20): Weather remains generally calm across central and southern districts, with isolated showers predicted in eastern high-range areas and northern inland pockets such as Nilambur.
Anizham (August 21) to Moolam (August 23): Isolated heavy rain is expected across Kozhikode, Wayanad, Kannur, Malappuram, Kasaragod, and eastern high-range regions of Ernakulam, Idukki, and Kottayam.
Pooradam (August 24): Rain activity intensifies significantly. Heavy to very heavy rainfall is projected across northern and central districts.
Peak Festival Days (Uthradam to Chathayam, August 25–28): Widespread heavy to very heavy downpours are predicted across all districts. The northern districts face the highest risk of severe rainfall toward the tail end of the festival week.

As this forecast is based on early numerical weather models, variations in intensity and track remain possible. Residents and travelers are advised to track daily updates as the festival week progresses.
