The current El Niño event is very strong, and is expected to affect weather around the globe, and in Colorado, through next spring. The impacts of El Niño are more complex over Colorado than other parts of the West. Strong El Niño conditions improve the odds for wetter-than-normal conditions in most parts of Colorado, especially in fall and spring.
