At this time, maximum sustained winds were near 45 mph. Wind direction is indicated by small barbs. White barbs point to areas of heavy rain.

One of the satellites forecasters use to verify surface wind speed is NASA's Quick scatterometer or QuikScat. QuikScat uses microwave technology that can actually see through clouds and analyze spinning winds of tropical cyclone on Earth's surface and measured Mirinae's winds before it made landfall.
NASA's Quick Scatterometer satellite (QuikScat) passed over Tropical Storm Mirinae on November 1 at 10:29 UTC (5:29 a.m. ET) and confirmed tropical storm force winds. QuikScat uses microwaves to peer into a storm's clouds and determine the speed of the rotating winds at the surface. At that time, maximum sustained winds were 57 mph.
On November 2 at 10 a.m. EDT or 7 p.m. local (Asia/Ho_Chi_Minh) time in Vietnam, Mirinae already crossed the South China Seas and made landfall in Vietnam. It made landfall around 1 a.m. EDT on November 2. It has since dissipated.
