    Phanfone to Target Japan Late Week

    While Kammuri curved east of Japan over the weekend, another threat looms later this week as Typhoon Phanfone approaches the region.

    While continuing on a northwest track through at least Friday, Phanfone has moved through an area of relatively low shear and warm ocean temperatures which allowed the cyclone to strengthen into a typhoon.

    A trough moving from China into Japan late this week will then attempt to steer the powerful cyclone northward. This track will take Phanfone toward Japan over the weekend or early next week.


    By this time, Phanfone could be an extremely dangerous typhoon with winds equal to or greater than a Category 3 hurricane.

    Depending on how quickly Phanfone tracks to the north and northeast, it could pass just east of Japan or make landfall as a typhoon capable of producing life-threatening conditions.

    Even if Phanfone passes just east of Japan, interaction with the trough to the north will pull heavy rainfall into eastern Japan, heightening the threat for widespread flooding and mudslides.

    A direct hit on Japan would be even worse as a combination of torrential rainfall and winds over 160 kph (100 mph) would be possible. The hardest hit areas would likely be the east-facing slopes of eastern Honshu, but the Greater Tokyo Area could also feel the brunt of this cyclone.


    Areas from the Ryukyu Islands north through the remainder of Japan should monitor this cyclone closely in the coming days to be best prepared for a potential landfalling typhoon.
