Typhoon MEGI was located at 11.0°N and 124.8°E at 0:00 (UTC time, the same below), near the Philippine Islands. It had a maximum wind speed of 20 m/s and a minimum pressure of 995 hPa near the center of the typhoon.

The true color image of FY-4A meteorological satellite (Fig. 1) shows that the circulation structure of typhoon MALAKAS is still developing, and that MEGI has an asymmetric structure. The infrared enhanced cloud image (Fig. 2) of FY-4A at 00:00 shows that the cloud top brightness temperatures of the circulation center of typhoon “MALAKAS” and “MEGI” are below -70℃.
