The past 24 hours of Typhoon Hinnamnor. JTWC estimates the storm has a category 5-equivalent intensity of 140 kt.

(Himawari-8 data are obtained from AWS, converted to netCDF with axitools, and plotted via Python.)

Choosing which individual ABI band to analyze: sometimes it's hard, sometimes it isn't

What goes up must come down? 48 hours of Typhoon #Nyatoh via Himawari-8.

JTWC estimates indicate the tropical cyclone intensified from 70 to 125 kt in 24 hours... and then weakened from 125 to 75 kt in the subsequent 24 hours.

Seven days of Hurricane #Douglas: from tropical depression to major hurricane to the closest hurricane on record to track along the north side of the Hawaiian islands (closer than 2016's Hurricane Lester).

Thankfully, no islands were directly impacted by the core of Douglas.

Now that #Arthur is extratropical, we can look back on its lifecycle from disturbance to tropical storm to extratropical system. This loop shows 5-minute Band 13 (infrared) imagery because Arthur remained within the CONUS ABI sector the entire time.

Stubborn #Sebastien strives for symmetry (but never succeeds) as seen via satellite

The past 24 hours of #Lorenzo, which is now a category 5 hurricane, the farthest east category 5 Atlantic hurricane that we know of.
