The IMD has issued an orange alert for nine districts in Kerala due to intensified monsoon activity. Flight diversions and heavy rainfall in hilly regions have already been reported.

Key Takeaways

  • Orange Alert for 9 districts including Kasaragod, Kannur, and Ernakulam.
  • Yellow Alert for 5 districts including Thiruvananthapuram and Alappuzha.
  • Flight diversions reported at Thiruvananthapuram International Airport.
  • Peerumedu recorded the highest rainfall at 11 cm.

The southwest monsoon remains highly active across Kerala, prompting the India Meteorological Department (IMD) to issue an orange alert for nine districts on August 1. The intensification is attributed to a depression over western Vidarbha and an off-shore trough extending from South Gujarat to North Kerala.

Aviation Disruptions Amidst Adverse Weather

The inclement weather has already begun impacting transportation. Due to poor visibility and adverse weather conditions, an IndiGo flight from Kochi to Maldives and an Air India Express flight from Bengaluru to Kochi were forced to divert to Thiruvananthapuram International Airport.

Why This Matters: BozokMedia Analysis

BozokMedia analysis shows that the combination of a depression and an off-shore trough creates a high-risk environment for landslides and flash floods in the Western Ghats. The heavy rainfall in districts like Idukki and Wayanad suggests that hilly terrains are at extreme risk.

The prevailing westerly to northwesterly winds combined with the current trough system indicate a prolonged spell of intense precipitation.
