NASA & NOAA - Suomi NPP satellite patch.

Oct. 10, 2018

Michael (Gulf of Mexico) 2018

NASA-NOAA’s Suomi NPP satellite examined Hurricane Michael after it reached Category 4 status and neared the Florida Panhandle on Oct. 10. Suomi NPP provided an infrared and night-time view of the powerful storm.


Image above: NASA-NOAA’s Suomi NPP satellite obtained a night-time view of Hurricane Michael in the Gulf of Mexico on Oct. 10 at 0732 UTC (2:32 a.m. CDT). At the time, Michael was a Category 4 hurricane and the eye was so well-defined it could be seen clearly by moonlight. Lights from population centers along the Gulf coast appear white.

At 9 a.m. EDT on Oct. 10, water levels were quickly rising and winds increasing along the Florida panhandle as potentially catastrophic Michael approached.

Satellite Imagery Reveal

NASA-NOAA’s Suomi NPP satellite obtained an infrared view of Hurricane Michael in the Gulf of Mexico on Oct. 10 at 0732 UTC (2:32 a.m. CDT). At the time, Michael was a Category 4 hurricane and the eye was so well-defined it could be seen clearly by moonlight. Infrared imagery revealed strong thunderstorms and tropospheric gravity waves in the northwest and western and eastern edges of the hurricane.

National Hurricane Center forecaster Daniel Brown described Hurricane Michael in visible and infrared imagery, “Michael is an extremely impressive hurricane in visible and infrared satellite imagery this morning. The eye has continued to warm and become even more distinct, while remaining embedded within an area of very cold cloud tops.”

Many Warnings and Watches in Effect

NOAA’s National Hurricane Center has noted many warnings and watches in effect.
