Atlantic explosive cyclogenesis

A hurricane-force low located in the central Atlantic Ocean is moving NE and causing exceptional wind speeds within the jet stream across the North Atlantic Ocean.

The cyclone underwent incredibly rapid intensification and is expected to pass west of Iceland on February 21 before it hits south Greenland.

"This jet is related to the intense bombogenesis cyclone that has developed last night in the north Atlantic," Severe Weather Europe meteorologists said.

"Wind speeds of almost 400 km/h are being observed approximately 10 km above the ground."

Earlier yesterday, around 00:00 UTC, the core was even stronger and wind speeds were up to 407 km/h!

The cyclone has gone through an incredibly rapid intensification and deepened below 940 hPa on the morning of February 20.

Within only 19 hours, this cyclone deepened for incredible 51 hPa - from 1 003 to 952 hPa.

51 hPa is more than double the threshold (24 hPa in 24 hours) for "explosive cyclogenesis" also known as "bombogenesis" and "bomb cyclone".
