Due easterly wind shear, the depression did not further intensify as it moved on a generally west-northwesterly track.
At roughly the same time, it turned more to the west, although it maintained a general northwesterly path.
Their persistent southeasterly trend suggests deposition of the loess by prevailing northwesterly winds, possibly anticyclonic winds blowing from the retreating ice sheet.
Most of this growth was in the northwesterly direction, and forests were cleared and marshes drained to provide room for this growth.
A temporary northwesterly turn occurred around this time as the storm moved through a weakness in the ridge.
Dominant northwesterly winds eventually caused blowing sand to become perched on the banks.
Most tropical cyclone prediction models indicated a northwesterly track that never happened, and also over-intensified the system.
Substantial aftershocks continued for more than a week after the initial event, moving in a northwesterly progression.
