The circulation of Typhoon Noru is very well organized.  There is a circular eye with a diameter of 20 miles (32 km) in the center of Noru.  The eye is surrounded by a wide ring of strong thunderstorms.  The strongest winds are occurring in this ring.  Bands of showers and thunderstorms are revolving around the core of Typhoon Noru.  Winds to typhoon force extend out about 45 miles (75 km) in all directions.  Winds to tropical storm force extend out about 150 miles (240 km) from the center.

Typhoon Noru is in a very favorable environment.  Noru is moving over water where the Sea Surface Temperature is near 30.5°C.  The upper level winds are weak and there is little vertical wind shear.  Typhoon Noru could maintain its intensity or weaken slowly over the next few days.

Typhoon Noru is moving around the western end of a subtropical ridge which is steering the typhoon slowly toward the west.  Noru is expected to start moving toward the north when it reaches the western end of the ridge.  On its anticipated track Typhoon Noru will remain south of Japan for much of the week.
