A Chinook wind is a warm, dry wind that descends the eastern slopes of the Rocky Mountains in North America. It's known for causing rapid temperature increases, melting snow quickly. Imagine waking up to a winter wonderland and then, suddenly, spring is here! 💨 These winds are created when air is forced up the mountains, loses its moisture, and then warms as it descends. Unlike a regular breeze, Chinooks can dramatically change local weather in a matter of hours.
