Typhoon Mawar (left) is captured with Tropical Cyclone Guchol in this satellite image. Both storms are far out in the north-western Pacific Ocean, some 900 kilometres from Tokyo.


They are travelling in parallel with each other, both headed roughly northwest at comparable speeds. Mawar, however, will strike mainland Japan on its projected course, and will have built to a Category 4 storm with sustained winds of over 320 kilometres per hour as it strikes shore around August 25.
Guchol, however, will never come close to shore if current projections are correct, and remain a substantially weaker system with peak winds less than half the speed of Typhoon Mawar.
