Hurricane Danielle 2022

Satellite images, weather maps and tracks of Category 1 Hurricane Danielle 2022, August 30 - September 13. Max wind speed 90mph.

Satellite imagery this afternoon (September 8) has shown Danielle develop a clear comma-shaped cloud shield, a hallmark of an extratropical cyclone. In addition, an ASCAT-B pass near 12:00 UTC showed a wind shift, indicative of a front, that extended from the center of the cyclone northeastward. Based on these data, Danielle has been classified as post-tropical and this is the last NHC advisory. Peak winds in the ASCAT pass were just above 60 mph (50 knots), so the intensity of Danielle was lowered slightly to 65 mph (55 knots). It is worth noting that the peak winds are generally not representative of the impacts associated with extratropical cyclones and gale- to storm-force winds extend well from the center of Danielle.

Danielle has begun its long-awaited counterclockwise loop, which should take another 36 to 48 hours to complete. After that, the post-tropical cyclone is forecast to move initially southeastward, then eastward as it is caught within the flow of a broader mid-latitude trough moving eastward over the northeastern Atlantic. The track forecast for the post-tropical cyclone is based heavily on the multi-model consensus TVCN. All guidance indicates the cyclone will gradually weaken, both in terms of maximum winds and size through the end of the forecast period.

Danielle continues to produce a large area of very rough seas over the central-north Atlantic.
