With rain intensifying throughout the state, the India Meteorological Department (IMD) has put five districts on red alert.

Pathanamthitta and Idukki were placed on red alert in the IMD's 1 pm update. Now, Alappuzha, Kottayam and Ernakulam have been upgraded from orange to red, meaning these districts are also expected to receive up to 204.4 mm of rainfall over the remainder of the day.

Except for the north Kerala districts of Kannur and Kasaragod, seven other districts are placed on orange alert. The intensity of rainfall in these districts is expected to range from heavy to very heavy (115.6-204.4mm).

At Bangalam in Kasaragod district, 70-year-old Keelath B Balan died in a lightning strike. He was hit by lightning while standing in front of his house Wednesday evening.

The IMD has predicted rainfall with thunderstorms in Kerala over the next five days. Cyclonic circulation hovering above southern Kerala is the reason for this, the IMD said in its update.
