Central Huerfano County in southeastern Colorado... * Until 245 AM MDT. * At 1141 PM MDT, Doppler radar indicated thunderstorms producing heavy rain across the northeast section of the Spring burn scar. Flash flooding and debris flows is expected to begin shortly. * Flash flooding will remain over mainly rural areas of central Huerfano County. Excessive rainfall over the burn scar will result in debris flows. The heaviest rain over the burn scar was occurring north of highway 160. PRECAUTIONARY/PREPAREDNESS ACTIONS... Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. Excessive runoff from heavy rainfall will cause flooding of small creeks and streams, country roads, farmland, and other low lying spots. 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. && LAT...LON 3767 10495 3756 10497 3755 10509 3769 10513 $$ Hodanish

At 1225 AM MDT, Doppler radar indicated thunderstorms producing heavy rain across the warned area, especially north of Highway 160. Flash flooding is expected. Excessive rainfall over northeastern and eastern sections of the Spring burn scar will result in debris flow moving through the Dog Springs Arroyo and North Abeyta Creek Drainages. The debris flow can consist of rock, mud, vegetation and other loose materials. PRECAUTIONARY/PREPAREDNESS ACTIONS... Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. Excessive runoff from heavy rainfall will cause flooding of small creeks and streams, urban areas, highways, streets and underpasses as well as other drainage areas and low lying spots. Remain alert for flooding even in locations not receiving rain. Arroyos, streams, and rivers can become raging killer currents in a matter of minutes, even from distant rainfall. 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. && LAT...LON 3767 10495 3756 10497 3755 10509 3769 10513 $$
