At 406 PM MDT, Doppler radar indicated thunderstorms producing heavy rain across the warned area. Up to 1.5 inches of rain has already fallen based on radar estimates. Flash flooding is expected to begin shortly if it is not already occurring. Excessive rainfall over the burn scar will result in flash flooding and debris flow moving through the Hayden Pass burn scar streams and drainages. The debris flow can consist of rock, mud, vegetation and other loose materials. Flash flooding will impact areas in and near the burn scar. PRECAUTIONARY/PREPAREDNESS ACTIONS... Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. Move away from recently burned areas. Life-threatening flooding of creeks, roads and normally dry arroyos is likely. The heavy rains will likely trigger rockslides, mudslides and debris flows in steep terrain, especially in and around these areas. Flooding is occurring or is imminent. It is important to know where you are relative to streams, rivers, or creeks which can become killers in heavy rains. Campers and hikers should avoid streams or creeks. && LAT...LON 3836 10574 3822 10563 3828 10586 3833 10583 $$ lw
