Tropical depression ARB 01 – Gaining strength now!
A week ago, the Upper Air Cyclonic circulations were forecasted to form intensify into a cyclone or a tropical depression on June 2 and move towards Gujarat and adjoining Sindh coast but that was delayed. The new forecast is that a low pressure will form on June 4 or June 5.
A low pressure is forecasted to either form on June 4 (tonight) or June 5 (morning), if that does not happen then chances will further reduce of a tropical depression formation, but latest forecast look good.
If a low pressure form and intensify into a well-marked low pressure and then a depression (depression could also intensify into a cyclone too during the period) then these tracks it might follow;
- According to BBC, the expected storm moves North west then west but later moves back to make landfall between Mumbai and Goa in India. It is worth mentioning that BBC is not changing this forecast since May 26. track similar to cyclone Phyan 2009.
- According to the GFS, the expected storm will move a towards the Maharashtra-Gujarat- coastal areas and from there it will start moving towards Oman.
- Other forecast is that, the storm will move towards Sindh-Gujarat coastline and then enter Rajasthan, a track followed by 1999 cyclone and 1998 cyclone and 1992 cyclone.
- Another is that, it will move from Sindh-Gujarat coast to Oman.
- Another, considering the sub-continent only is that the storm will hit Oman and then recurve to Balochistan but it will move towards south Punjab instead coastal Sindh as a remnant, somewhat similar path to cyclone Phet 2010.
- Possibility of Gonu-like track also persist.
These tracks and intensity will keep on changing day by day even if a cyclone forms, as cyclones are hard to predict. But if it forms then the changes will be small.
Oman – First Gonu, then Phet, now Keila??
Very heavy rainfall to extremely heavy rainfall likely in Oman especially the capital Muscat where more than 100 mm rainfall is likely with strong wind storms of 50 mph from June 9.
Gwadar- memories of Phet or Gonu??
Heavy rainfall likely in the sea port city of Balochistan, Pakistan. Rain could reach above 70 mm with winds up to 45 mph or greater from June 9.
Karachi dumped again!
No major rainfall likely in Karachi as storm will be far away from Sindh. But moderate showers with fast to strong winds could occur due to the developement of some thunderstorms near Sindh due to the tropical depression from June 7.
These all are forecast as of June 4, could change in the days to come.
If the storm threatens Pakistanis coastline especially Sindh then Pakistan Weather Portal (PWP) will give updates, breaking news and news alert.
