1-minute Mesoscale Domain Sector GOES-19
(GOES-East) Visible and Infrared images
(above) showed
Hurricane Erick as it intensified from a Category 2 storm at 1800 UTC on 18 June to a Category 3 storm by 0000 UTC on 19 June 2025. The eye became a bit more defined during that time period — and convective bursts within the eyewall occasionally exhibited cloud-top infrared brightness temperatures of -80ºC or colder (violet pixels embedded within brighter white regions).
Erick was moving through an environment characterized by low values of deep-layer wind shear (below) — a factor that favored further intensification.

A DMSP-18 Microwave image at 2154 UTC on 18 June (below) displayed a large outer eyewall (and hints of a partial inner eyewall), suggesting that an eyewall replacement cycle might soon occur.

1-minute GOES-19 Infrared images
(below) showed the period where Erick continued its rapid intensification, becoming a Category 4 storm just before 0600 UTC on 19 June. The hurricane weakened somewhat to Category 3 intensity shortly before making landfall in far western Oaxaca, Mexico around 1200 UTC on 19 June (and the eye became ill-defined closer to the time of landfall). Convective bursts west of the eyewall occasionally reached -90ºC (yellow pixels embedded within darker purple areas).

Deep-layer wind shear remained very low in the vicinity of Erick
(below), maintaining a favorable environment for intensification — and the hurricane also traversed very warm
Sea Surface Temperatures during its period of rapid intensification.

A DMSP-18 Microwave image at 1030 UTC on 19 June (below) suggested that landfall might have occurred a bit earlier than 1200 UTC.
