Himawari-8 Advanced Himawari Imagery (AHI) from the ‘Target’ sector, above, show a strong albeit asymmetric storm south of Ise Bay and southwest of Tokyo Bay. Clean window infrared (10.41 \u00b5m) imagery, above, shows a compact eye that is cooling with time, suggesting weakening (and\/or becoming more cloud-filled). Most of the cold clouds in the storm are north of the center, a distribution that suggests shear.\u00a0 However, the storm is still producing strong convection that is wrapping around the eye<\/span>. By the end of the animation, at 1929 UTC, the eye is no longer distinct.\u00a0 This toggle compares the 1432 and 1929 UTC images<\/a>.\u00a0 A decrease in storm cloud-top organization near the eye is apparent.<\/p>\n

Data from the CIMSS Tropical Page at 1530 UTC on 11 October, shown below in a stepped animation, show southerly shear<\/a> that will increase with time over the storm as it moves towards Japan. Microwave imagery<\/a> (85 GHz) also suggest a sheared storm, as does the infrared imagery<\/a>.\u00a0 Low-level water vapor imagery (7.3 \u00b5m), here<\/a>), shows dry air (yellows in the color enhancement chosen) prevalent over the southern half of the storm.\u00a0 These data suggest that a slow extratropical transition is underway.<\/p>\n

The Airmass RGB image over the Pacific Basin, (animation<\/a>), (from this site<\/a> at CIRA) also shows dry air consistent with a transition from tropical to extratropical. The zoomed-in image of the Airmass RGB, below, from Real Earth<\/a>, shows the dry air as shades or orange\/copper southwest of the storm, in contrast to the deep tropical moisture, feeding into the storm from the south, that is greener.<\/p>\n

Suomi NPP overflew Hagibis at 1639 UTC on 11 October.
