On June 8, 2023, the Moderate Resolution Imaging Spectroradiometer
(MODIS) on NASA’s Aqua satellite acquired a true-color image of Typhoon
Guchol (Chedeng) as it strengthened over the Philippine Sea. Near the
time this image was captured, Typhoon Guchol was a large storm carrying
maximum sustained winds of about 90 mph (145 m/h) (Category 1 on the
Saffir-Simpson Hurricane Wind Scale).

Since its formation north of Palau on June 6, Guchol had been traveling
westward, appearing to be taking aim at the Philippines. However, as
the typhoon’s asymmetric shape illustrates, Guchol has run into
difficult conditions between the storm and the Philippines. The adverse
conditions sheared the western side of the storm, but also has shifted
Guchol’s track towards the northeast. The shiny silver streak visible
west of the storm is not associated with either the typhoon or wind
shear, and it has no effect on weather conditions. It is an optical
phenomenon called “sun glint” which occurs when the rays of the sun
reflect off the water and directly back to the sensor.

At 11:00 pm EDT on June 8 (0300 UTC June 9), the Joint Typhoon Warning
Center (JTWC) advised that Typhoon Guchol was carrying maximum
sustained winds of 92 mph (148 km/h) and was located about 663 miles
(1,067 km) south-southeast of Kadena Air Base, Okinawa, Japan and was
traveling north-northwestward. The storm was still strengthening, but
peak winds are expected to reach 98 mph (158 km/h) on June 9 before
winds begin to weaken. Typhoon Guchol is expected to continue to travel
northwestward, avoiding landfall on either the Philippines or Japan.
