The ‘bombogenesis’ of the new intense cyclone the North Atlantic is underway! A rapid intensification has been ongoing since last night, as the pressure drop of more than 30 mbar overnight has been observed. A very impressive satellite presentation is appearing this morning. Cyclone is on track with the previous model forecast guidance and will be nearing Iceland as an intense near 935 mbar extra-tropical cyclone tonight!

#Weatherporn over Iceland – an extremely deep cyclone produces the most epic satellite presentation of the season


Some incredibly impressive satellite images are visible this morning, as an extra-tropical cyclone continues rapidly intensifying in the North Atlantic, moving towards Iceland. Notice a strong dry intrusion pushing from the SW, while the cyclone is beginning to show a textbook cyclonic appearance.

The latest surface analysis reveals a very large cyclone expanded across much of the North Atlantic, minimum cental pressure is around 950-952 mbar. The pressure drop along its path has been incredible overnight and continues this morning. As seen from the buoy #4101664 data, the pressure change in the past 8 hours has been around 29 mbar! That is extremely impressive and fits into a ‘bomb cyclone’ e.g. rapid intensification cyclone definition – pressure change of more than 24 mbar during the 24-hour period – more than obviously! The buoy is located just due WSW of the low’s center.

The cyclone is expected to continue with rapid intensification for additional 9-12 hours while it pushes into mid 930s tonight.

Please refer to the previous discussion for forecast details:

North Atlantic is on roll again as another ‘bombogenesis’ – bomb cyclone is rapidly developing, deepening into a violent mid 930s extra-tropical cyclone near Iceland tomorrow
