A false-colour radar image from the Copernicus Sentinel-1 satellite, captured on 28 September 2026, shows the surface of the Philippine Sea beneath the clouds as Typhoon Surigae passed about 200 km south of Shikoku, Japan, according to ESA. By 1 October, the storm, also known as Typhoon no. 26, was almost 1000 km away, roughly 200 km south of Tokyo.

The image was produced using two radar polarisations, each assigned to a different colour. The calm seas at the storm's eye appear dark blue, while an orange-yellow ring marks rough ocean conditions and strong winds. Lighter blue areas likely indicate lower wind speeds, less sea surface movement or rain, and bright yellow flecks in the lower part of the image are most likely concentrated wind and rain rather than land.

When the image was acquired, Surigae had maximum gusts of up to 240 km per hour, with swells and waves reaching up to 7 m. ESA reports the storm has since weakened considerably and is currently classed as a tropical depression with maximum wind speeds of 55 km per hour.
