NASA infrared satellite data revealed that Tropical Storm Halong is surrounded by strong thunderstorms and an eye appears to be developing.

When NASA's Aqua satellite passed over Tropical Storm Halong on July 29 at 03:29 UTC (July 28 at 11:29 p.m. EDT) the Atmospheric Infrared Sounder instrument captured data on the . The showed very cold, high thunderstorm cloud top temperatures of powerful storms surrounding the center, with what appears to be an eye developing. Microwave also shows a small eye, with tightly-curved bands of wrapping into it.
