Himawari-8 Clean Window Infrared (10.41 \u00b5m) imagery shows Super Typhoon Yutu poised to hit Tinian and Saipan in the Marianas Islands, to the northeast of Guam. The 0900 UTC Advisory from the Joint Typhoon Warning Center shows a storm with sustained winds of 145 knots, with strengthening forecast. JMA estimates a surface pressure of 905 hPa<\/a>!

Update: Landfall on Tinian and Saipan occurred just before 1500 UTC; a closer view using 2.5 minute rapid scan Himawari-8 imagery can be seen here<\/a> (station plot PGSN<\/a> is Saipan, where reliable observations<\/a> ceased after 1452 UTC).<\/p>\n

Added: From William Straka, CIMSS. NOAA-20 had a fortuitous overpass, almost directly over Tinian at landfall. The Day Night Band Visible (0.7 \u00b5m) Imagery (with a full moon) and 11.45\u00a0\u00b5m infrared imagery is shown below).<\/p>\n

CIMSS helps manage a Direct Broadcast (DB) antenna at the National Weather Service on Guam<\/a>, and that antenna received both NOAA-20 and GCOM data as the eye was over, or close to, Tinian.\u00a0 Microwave imagery from\u00a0The Advanced Microwave Scanning Radiometer 2 (AMSR-2<\/a>) on JAXA’s GCOM<\/a> satellite, below, (courtesy Kathy Strabala, CIMSS) at 36.5 GHz<\/a> and 89.0 GHz<\/a>, reveals cloud and rainband structures that infrared imagery cannot.\u00a0 In particular, the 89.0 GHz imagery suggests the formation of an outer eyewall ouside the very compact inner eye.\u00a0 This typically is the start of an eyewall replacement cycle.<\/p>\n

The DB antenna also processed data from NOAA-20, the same overpass as shown above, zoomed in over Tinian. The antenna is able to capture data over much of the western Pacific Basin, as the Day Night Band visible image shows below. A true color image from the previous overpass on Guam, 12 hours earlier, during daytime (0311 UTC on 24 October), is here<\/a>.<\/p>\n
