The San Juans remain a bullseye in precipitation\nforecasts this afternoon and again on Friday, maintaining flash\nflood threats redeveloping each afternoon. However, available\nmoisture is higher moving west into Utah, which leaves the potential\nfor isolated storms to produce hourly rainfall rate of 1-2 in.\nTherefore, areas of concern remain unchanged from the previous\nforecast for this afternoon.\n\nStorms over the last 24 to 48 hours have only helped prime lower\nlevels of the atmosphere and saturate the ground where rain was\nobserved. Several locations across southwest Colorado reported over\n0.5 inches of rain within 30 minutes during yesterday's convection;\nwhich is more than sufficient to create issues in our steep, rocky\nterrain already 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 the\nweek and stay tuned for updated hydro alerts if visiting or if you\nreside below vulnerable terrain to flash flooding and/or debris\nflows. Storms across the west develop quickly, leaving little room\nfor lead time in flashy terrain."}
