00:00:00,060 --> 00:00:04,070
On October 24, the GPM Core Observatory passed directly over the eye of Super Typhoon Yutu.

2
00:00:04,090 --> 00:00:08,080


3
00:00:08,100 --> 00:00:12,140
This was a rare overpass of the super typhoon just as it made landfall on the islands of Tinian and Saipan.

4
00:00:12,160 --> 00:00:16,190


5
00:00:16,210 --> 00:00:20,230
Yutu is tied with Super Typhoon Mangkhut for the strongest tropical storm of 2018.

6
00:00:20,250 --> 00:00:24,250


7
00:00:24,270 --> 00:00:28,290
Yutu is the equivalent of a Category 5 hurricane.

8
00:00:28,310 --> 00:00:32,360
Typical of such a strong storm, the eyewall is nearly uniform around the eye.

9
00:00:32,380 --> 00:00:36,390


10
00:00:36,410 --> 00:00:40,420
GPM also saw a "moat" of low precipitation surrounding the eyewall.

11
00:00:40,440 --> 00:00:44,460


12
00:00:44,480 --> 00:00:48,560


13
00:00:48,580 --> 00:00:52,620
The eyewall is particularly tall with few hot towers, indicating a relatively mature storm.

14
00:00:52,640 --> 00:00:56,670


15
00:00:56,690 --> 00:01:00,730


16
00:01:00,750 --> 00:01:04,780
Peeling back the layers of Yutu reveals the most intense precipitation at low altitudes.

17
00:01:04,800 --> 00:01:08,840


18
00:01:08,860 --> 00:01:12,890
