A curtain of fog often accompanies the clash between warm to the west and cold to the east. The effects are similar to those of an Alberta Chinook, though not to the same extreme, in part because the Okanagan is relatively warmer than the Prairies, and because of the additional number of precipitation-catching mountain ranges between Kelowna and Calgary. Chinooks are even more prevalent east of the Canadian Rockies, in Alberta. And it's not always windy across the city.

A class of people known as chinook patients claim that their physical or mental health, and sometimes both, are impaired by the wind (Nkemdirim 1985, 1993). They often bring the lowest relative humidity of the year to coastal Southern California. When the warm, dry, fast-moving Chinook winds pass over snow-covered areas, the snow often vaporizes before it has a chance to melt, according to the U.S. Geological Survey.

As moist winds from the Pacific (also called "Chinooks") are forced to rise over the mountains, the moisture in the air is condensed and falls out as precipitation, while the air cools at the moist adiabatic rate of 5 °C / 1000 m (3.5 °F / 1000 ft). Also, trains have been known to be derailed by chinook winds there. As a consequence of the different adiabatic rates of moist and dry air, the air on the leeward slopes becomes warmer than equivalent elevations on the windward slopes.
