The powerful low-pressure system formed over the North Atlantic out of the remnants of Hurricane Isaias. Extratropical Cyclone Whips Past Iceland. NASA Earth Observatory Oct 21, 2026 Article View more Images of the Day: Oct 20, 2026 Instruments: NOAA-21 — VIIRS Topics: Extreme Weather Hurricane Isaias—the only Atlantic hurricane to date in 2026—made landfall in Florida as a Category 2 storm on October 9.
After delivering a rainy, windy blow to the U.S. Gulf Coast and drenching much of the Eastern Seaboard, the weather system had more in store. Riding the jet stream east over the North Atlantic, Isaias’s remnants developed into a powerful storm known as an extratropical cyclone.
These low-pressure systems often feature asymmetrical, comma-shaped cloud patterns and can strike with hurricane-force winds, rain, and blizzard-like conditions. The VIIRS (Visible Infrared Imaging Radiometer Suite) on the NOAA-21 satellite captured this image of the extratropical cyclone brushing past Iceland on the afternoon of October 14. During its journey, the system’s air pressure plummeted by more than 50 hectopascals over a 24-hour period, reportedly —about double the criteria for explosive cyclogenesis, or bombogenesis.
Some meteorologists believe the storm may have set a new October low for barometric pressure in Iceland, after correcting for altitude, likely breaking a record that has stood since 1963.
