The National Weather Service in Medford, Oregon, at 10:00 AM Wednesday morning, September 6th, has issued a FLASH FLOOD WATCH IN EFFECT FROM THURSDAY MORNING SEPTEMBER 7, 2017 THROUGH LATE THURSDAY EVENING SEPTEMBER 7, 2017, FOR BURN SCAR AREAS.
Officials are warning that heavy rain with thunderstorms could produce flash flooding on burn scarred areas in portions of northern California and Oregon, including the following areas, in northern California, South Central Siskiyou County, and Western Siskiyou County. In Oregon, Central Douglas County, Curry County Coast, Eastern Curry County and Josephine County, Eastern Douglas County Foothills, Jackson County, Siskiyou Mountains and Southern Oregon Cascades, and South Central Oregon Cascades.
Thunderstorms on Thursday are predicted to contain high amounts of moisture. Heavy rains are possible which will pose a threat to areas on and around recent wildfires from Thursday morning through Thursday evening.
An unusually moist air mass over the region will combine with thunderstorms to produce the threat of heavy rainfall. If these heavy rains fall on burn scar areas, dangerous runoff could result. Flash flooding, debris flows, and/or mudslides may occur in and down drainage from recent wildfire burn scars.
Landslides and debris flows are possible during this flood event. People, structures, and roads located below steep slopes, in canyons and near the mouths of canyons may be at serious risk from rapidly moving landslides.
A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a VERY DANGEROUS SITUATION. Residents should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
