The India Meteorological Department on Tuesday issued a red alert for the mountain district of Wayanad -- which has been rocked by landslides triggered by incessant rains -- and all the northern districts of Kerala, indicating that extremely heavy rainfall is expected in these regions.
While the IMD has issued a red alert for eight districts, including Wayanad, an orange alert was issued for Tuesday for Pathanamthitta, Alappuzha, Kottayam and Ernakulam districts.
A red alert indicates heavy-to-extremely heavy rain of over 20 cm in 24 hours. An orange alert means very heavy rain of 11 cm to 20 cm, and a yellow alert means heavy rainfall between 6 cm and 11 cm.
The red alert was issued for Tuesday in Palakkad, Malappuram, Kozhikode, Wayanad, Kannur and Kasaragod districts in northern Kerala, as well as Idukki and Thrissur in central Kerala.
