Rarely seen in Australian waters, there are two tropical storms within close proximity of one another. The southernmost storm is the weaker of the two and is named Tropical Storm Twenty Seven while the northernmost storm is Tropical Cyclone Seroja.
It appears that both storms will come close enough to one another to influence each other’s wind fields and it is possible that both storms may start to rotate around each other. At the present time, both storms will remain offshore but because there are two storms, forecasting what they do will be more difficult than usual.
It appears that both will remain offshore but there is still a risk that one being Tropical Cyclone Seroja could approach the Pilbara Coast or Gascoyne over coming days.
Tropical Cyclone Seroja is still expected to reach peak intensity as a Category three storm in coming days but once it starts to cross over colder waters close to the Tropic of Capricorn, this storm will commence its weakening phase.
Having two such storms within close proximity to one another within Australian water is a rare event and forecasting what they do will become a challenge in coming days.
