Hurricane Danielle Discussion Number  28
NWS National Hurricane Center Miami FL       AL052022
300 AM GMT Thu Sep 08 2022

Danielle is beginning to feel the effects of an approaching mid-to
upper-level trough just to its west. There has been some erosion of
the deep convection over the southern portion of the circulation,
likely due to increasing southwesterly shear, while the eye has
filled with cloud cover. The latest Dvorak intensity estimates have
overall lowered since the previous advisory, and a blend of these
values suggest the cyclone's initial intensity has decreased to 65
kt.

The cyclone is expected to undergo extratropical transition through
Thursday morning due to the higher shear, interaction with the
trough, and sharply cooler SSTs along its forecast track. These
conditions are also expected to cause Danielle to gradually weaken.
The latest NHC intensity forecast was tweaked slightly lower than
the previous one, and closely follows the various multi-model
consensus values.

Danielle is moving northeastward at 15 kt, and this general motion
should continue through tonight. A slow down and counterclockwise
loop is expected to occur on Thursday and Friday when the cyclone
interacts with the trough that is expected to cut off. After that
time, a faster motion to the southeast is forecast, which should
take the extratropical cyclone toward western Europe by the end of
the period. The NHC track forecast is little changed from the
previous one, and is near the latest consensus aids.

Danielle continues to produce a large area of very rough seas over
the central-north Atlantic.  More information can be found in the
