Super Typhoon Jebi is now a cat 5 and strogest storm yet this 2018. Typhoob Jebi threatens Japan as per forecast shows
Jebi maintaining its strength as it tracks west-northwestward over the eastern Philippine Sea...
1800 UTC position [JMA]: 19.1°N 140.3°E (1515 km SE of Kadena AFB, Okinawa)
Movement: WNW at 13 knots (25 km/h)
Intensity [JTWC]: 150 knots (280 km/h) 1-min
Intensity [JMA]: 105 knots (195 km/h) 10-min
Central pressure: 915 hPa
#Jebi (STY #25W) is maintaining Category 5-equivalent intensity while moving across the eastern Philippine Sea well to the south of Iwo To. However, it is beginning to show signs of an eyewall replacement cycle. Convection between the inner and outer eyewalls has been warming (weakening), and this is evident even on the plain, non-enhanced infrared satellite image. The eye remains well-defined on both infrared and microwave satellite imagery, and the inner eyewall has not yet begun to collapse. The system is maintaining excellent outflow in all quadrants. CIMSS ADT and SATCON estimates are slowly beginning to fall as the convection warms, but still remain high and support Category 5-equivalent strength. Manual Dvorak estimates from SAB, JTWC, and JMA are also starting to drop a bit.
Although Jebi remains over waters with SSTs of around 29°C, it is beginning to cross into an area of shallower heat content that cannot support an extreme intensity. This combined with the eyewall replacement cycle is likely to cause Jebi to begin a gradual weakening trend during the next several days as it makes a wide turn toward the northwest, then north and passes between Iwo To and the Ryukyu Islands. Depending on how quickly Jebi finishes its eyewall replacement cycle, the intensity could level off in about 24 hours before cooler waters and slightly increased southwesterly wind shear cause it to resume weakening. Nonetheless JMA forecasts a very strong typhoon to be near the south coasts of Shikoku and Honshu by late Monday.
