The trough gradually decelerated as high pressures altered the upper level flow to that of an easterly flow.
The easterly flow blew over a long fetch of open waters, thus producing low-level convergence.
Embedded within an easterly flow ahead of a mid-level trough, the storm turned towards the north-northeast and accelerated slightly.
Over the next few days, the system was steered westward due to easterly flow.
Rapidly moving towards the west, the depression was embedded in deep easterly flow.
The unusual amount of rain was caused by "a strong low-level easterly flow which forced the moist unstable air up-slope on the hills.
In general, easterly flow occurs at low and medium latitudes globally.
"But then as the sea breeze progresses to the west with the easterly flow, we should actually see an improvement in our weather at the launch pad."
At the same time, a high pressure center was sitting farther north in Labrador, keeping an easterly flow of very cold air near the surface.
Embedded within broad easterly flow, the storm turned west-southwestward, a heading it would retain until dissipation, and accelerated.
