THE JOURNEY OF THE SEVERE CYCLONIC STORM "MAHA", FOURTH CYCLONE OF THE  SEASON IN THE ARABIAN SEA. TOTAL 6 CYCLONES HAVE FORMED IN THIS SEASON TILL PRESENT.

Highlights:

1) Cyclone Maha the 4th cyclone formed in the Arabian sea.

2) The Journey of the severe cyclonic storm maha.

3) Cyclone Kyarr has now weakened into Depression over the west-central Arabian sea.

India: The Arabian sea is on fire mode as back to back weather systems are forming in the basin, these weather systems are also becoming more marked due to favorable conditions such as low vertical wind shear, Warm sea surface temperatures, abundant availability of moisture, high humidity levels, etc:-. Normally only 1 cyclone or 2 cyclones forms in the Arabian sea by records. But now due to climate change the dynamics of the Arabian sea are changing, more cyclones are forming and also they are becoming more intense. Researches also say that there will be more intense cyclones as the temperatures are increasing.

The 2019 north Indian ocean cyclone season is the most active cyclone season on record in terms of accumulated cyclone energy(ACE),  surpassing 2007. Furthermore, the season has been active, with six cyclonic storms, one severe, four others formed as very severe cyclonic storms and one super cyclonic storm. ACE is a measure of the power of a tropical or subtropical storm multiplied by the length of time it existed. It is only calculated for full advisories on specific tropical and subtropical systems reaching or exceeding wind speeds of 63 km/h (39mph).

The Journey of Severe Cyclone "Maha" as per IMD:


  1. On 29th October, a low-pressure area intensified into the well-marked low-pressure area over the Comorin area and adjoining the equatorial Indian ocean.
  2. In the next 12 hours, it concentrated into a depression over the Maldive, coloring area & adjoining Lakshadweep area.
  3. On 30th October at 2:30 pm thee, depression further strengthened into a deep depression over Lakshadweep and adjoining S.E Arabian sea.
  4. Favorable conditions led to the rapid development of the system and in just 3 hours at 5:30 pm on 30th October it intensified into a cyclone, after which it was assigned the name "maha".
  5. It crossed the Lakshadweep island as a cyclonic storm with winds up to 80kmph.
  6. Amini Devi and Minicoy received extremely heavy rains of about 301mm and 119mm respectively.
  7. In the next 24 hours on 31st October, the system intensified into a severe cyclonic storm about 300 km off north Karnataka coast.
  8. Its movement during its journey was north/northwestwards till today.

   Severe cyclone maha tracked by IMD:



The system is going to intensify further into a very severe cyclonic storm in the next 6-12 hours. This system is very likely to track west/northwestwards till 5th November and enter the west-central Arabian sea. But from 5th November it is very likely to track northeastwards towards the Indian west coast due to the western disturbance.

Observed and Future Track of Severe Cyclone Maha as per IMD:


The cyclone Kyarr has weakened into depression in morning hours, it is very likely to weaken into the well-marked low-pressure area during the next 6-12 hours, tracking southwards.
