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.
