An extratropical cyclone, also known as a mid-latitude cyclone, is a low-pressure system that develops outside of the tropics and has characteristics such as cold fronts and warm fronts. Other synonyms for extratropical cyclones include mid-latitude lows, wave cyclones, and frontal depressions. Extratropical storms are also commonly referred to as Nor'easters, as they often form and intensify off the northeastern coast of the United States. These weather phenomena can bring strong winds, heavy rainfall, snow, and even tornadoes, making them a significant threat to coastal communities. Despite their name, extratropical cyclones can also occur in tropical regions under certain conditions, such as in the case of hybrid storms or subtropical cyclones.
