NASA-NOAA satellite identifies typhoons strongest sectors

Satellite infrared data from Typhoon Goni helps identify the strongest part of the storm (red) as the south and eastern quadrants.

The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi satellite captured an infrared image of Goni on 18 August at 4:18 UTC.

The Joint Typhoon Warning Center noted that animated enhanced infrared satellite imagery showed a slight warming of convective tops, which means that they weren't reaching as high into the troposphere as a result of weakening uplift or push in the atmosphere. Otherwise, the system has maintained overall convective signature with tightly-curved banding wrapping into a 15-nautical mile diameter eye.

At the time of imaging, Typhoon Goni had maximum sustained winds near 100 knots (185.2 km/h).That makes Goni a Category Three typhoon on the Saffir-Simpson Scale. Goni is not expected to strengthen further. The Joint Typhoon Warning Center expects Goni to approach and pass north of Luzon, Philippines by 20 and 21 August 20 before approaching Taiwan from the southeast.
