Super Typhoon Yutu: Strongest Hurricane to Strike Mariana Islands to Date

This short video shows the path of Super Typhoon Yutu — a.k.a. “Rosita” in the Philipines — as it tracks from eastern Micronesia, through the Mariana Islands, across the Philippine Sea, and then across the northern tip of Luzon in the Philippines.

While this video is only 23 seconds long, it actually covers a period of ten days from October 22, 2018 20:00 UTC/GMT to November 1, 2018 09:30 UTC/GMT. The video consists of 284 frames, which are images that were taken by the Himawari-8 Japanese weather satellite. I colorized the frames in Adobe Photoshop, and then I saved the video at 12 frames per second so that the movie isn’t overly jerky, and also so that the file size isn’t too big, for those of you who may wish to download it for future reference.

Being as I did not begin downloading the satellite images until October 22nd, the video does not show the initial birth and formation of Yutu when it was still a Tropical Disturbance, then a Tropical Depression and then a Tropical Storm. The video begins when Yutu is already a typhoon, and is located a few hundred miles southeast of the Mariana Islands. Guam and the Mariana Islands are located in the dead center of this video.

When the eye of Super Typhoon Yutu struck Tinian and Saipan in the Commonwealth of the Northern Mariana Islands — about 150 miles north of Guam — on October 25th, it had maximum sustained winds of 180 m.p.h., with higher gusts of 190 m.p.h. It had a minimum central pressure of 905 millibars. In short, it was an extremely dangerous Category 5 storm.

After passing through the Mariana Islands, Super Typhoon Yutu weakened a little, but it still maintained maximum sustained winds of 150-165 m.p.h. — and thus, Category 5 status — as it crossed the Philippine Sea. By the time it crossed Luzon in the northern Philippines several days later, it had been downgraded to a Category 1 typhoon with maximum sustained winds of 90 m.p.h. and higher gusts to about 115 m.p.h.

According to Wikipedia and various weather websites, Super Typhoon Yutu is the most powerful tropical cyclone to ever strike the Mariana Islands up until this current time. That is, up until October 25, 2018. It is also the second-strongest system to hit the United States and its protectorates by wind speed, and likewise the third most-intense storm by barometric pressure. Furthermore, Yutu was the most powerful tropical cyclone worldwide in 2018.
