Rainfall rates of 1-2 inches\nper hour will be possible with the stronger storms. These rates\ncould lead to flash flooding and debris flows especially over\nrecent burn scars.\n\nStorms over the last few days have helped prime lower levels of\nthe atmosphere and saturate the ground where rain was observed.\nSeveral locations across southwest Colorado have reported 0.5\nto 1.0 inches of rain within 30 minutes; which is more than\nsufficient to create issues in our steep, rocky terrain that is\nalready susceptible to flash flooding. This environment also\ntriggers heightened awareness over recent (or actively burning)\nfires, due to the burnt ground's inability of absorbing moisture\nunder heavy rainfall. As such, we continue to emphasize the\npotential for flash flooding and debris flows in this regime.\n\nAs a reminder: Keep an eye on our forecasts through the end of\nthe week and stay tuned for updated hydrology alerts if\nvisiting or if you reside below vulnerable terrain to flash\nflooding and/or debris flows. Storms across the west develop\nquickly, leaving little room for lead time in flashy terrain."}
