Those winds coming from the Juan de Fuca Strait are a product of several factors, but the two most important are daytime heating of the land surrounding the Strait and the fact that there is almost always higher pressure over the open ocean and lower pressure over inland Washington. Now air likes to flow from high to low pressure, so if there is higher pressure over the open Pacific than over Washington, the air filling the Strait will flow from west to east…”
