- The very severe cyclonic storm Vayu is expected to “recurve” and make landfall as a “depression” by midnight near Porbandar in coastal Gujarat, the India Meteorological Department (IMD) forecast.
What does mean depression?
- A depression is the lowest grade of a cyclonic storm and brings wind speeds of 28-33 knots (or 55-65 kmph).
Where it landfalls?
- A map of the tropical storm’s trajectory shows it is likely to make landfall in a swathe of area adjoining Porbandar and Junagadh districts.
Advancement of monsoon
- Along with the cyclone, according to the IMD, the monsoon had further advanced into the remaining parts of northeast Bay of Bengal, some more parts of northwest Bay of Bengal, most parts of northeast India and some parts of north Bengal and Sikkim.
Recurving of cyclone to east
- Climate trends say that while there has been an increase in the number of tropical cyclones in India’s neighbourhood, there is no clear trend in recurving ones.
- While the typical cyclone in the southern hemisphere tends to have a westward slant, the recurving ones can suddenly incline east. That makes them harder to predict, according to meteorologists.
- While recurving cyclones don’t usually threaten Indian coasts, Ockhi — that skirted through Kerala’s and Tamil Nadu’s coasts in 2017 — was a notable re-curving cyclone.
