...CRITICAL FIRE WEATHER CONDITIONS THURSDAY AND FRIDAY... Strong northwest winds will spread across the northeast plains after sunrise today, with gusts 45 to 65 mph creating critical fire weather conditions despite somewhat marginal humidity values near 20%. Early Friday, westerly downslope winds will bring strong gusts to the Front Range mountains and foothills, with potential for these to spread into wind-favored portions of the adjacent lower elevations. Peak gusts of 70-90 mph are increasing in likelihood for the windiest locations (considerably lower for areas along and east of I-25). With a warmer and drier air mass in place, humidity values in the teens look to extend into much of the foothills, and certainly across the lower elevations. Such conditions may be a longer duration than usual, with potential for low humidity to extend into the evening hours prior to the arrival of a front. The National Weather Service in Denver has issued a Fire Weather Watch for wind and low relative humidity, which is in effect from Friday morning through Friday evening. * AFFECTED AREA...Fire Weather Zones 215, 216, 241, 243, 245, 246 and 247. * TIMING...From Friday morning through late Friday evening. * WINDS...West 25 to 35 mph with gusts up to 80 mph in and near the foothills. West 15 to 25 mph with gusts up to 45 mph for areas roughly along and east of I-25. * RELATIVE HUMIDITY...As low as 10 to 15%. * IMPACTS...Conditions will be favorable for rapid fire spread. Avoid outdoor burning and any activity that may produce a spark and start a wildfire.

The Cossatot River is an 89-mile-long (143 km) river in Howard, Polk and Sevier counties in the U.S. state of Arkansas.The Cossatot begins in the Ouachita Mountains southeast of Mena, Arkansas. The river flows through the Ouachita National Forest and then in a generally southerly direction until it empties into Gillham Lake. After exiting Gillham Lake the river becomes leisurely until it joins with the Little River at the site where it empties into Millwood Lake.
Cossatot comes from an Indian term which translates roughly to skull crusher. The Cossatot is known as a difficult (class II - IV+) whitewater stream to canoeists and kayakers and a section at Cossatot Falls in Howard County, Arkansas has been called "the most challenging section of whitewater between the Smokies and the Rockies," though there are many more challenging runs in the state of Arkansas, such as Richland Creek, Crooked Creek or the Upper Buffalo (Hailstone run). An 11-mile (18-km) section including Cossatot Falls is designated as the Cossatot River State Park-Natural Area. Cossatot Falls is a series of back-to-back class III-IV+ rapids that drops around 40 feet in 1/8 of a mile. Rapid names are Cossatosser (class II+), Eye Opener, B.M.F. (class III), Washing Machine (class IV+), Whiplash, (class III+), and Shoulderbone (class II), with Deer Camp Rapid (class III), Devil's Hollow Rapid (class III+), and Devil's Hollow Falls (class IV) located downstream of the Falls area. Zigzag (Class III) and the Esses (class III) are other notable rapids on the Cossatot, located above the Falls. Whitewater rapid classes vary depending on water level. At certain higher levels near flood state, almost all of the Cossatot Falls turn into one long rapid.
The World War II fleet oiler USS Cossatot (AO-77) is named after this river.
Camping sites are located near the Cossatot Falls area, and at the nearby Brushy Creek Recreation area.
The Cossatot is listed as a National Wild and Scenic River and an Arkansas Natural and Scenic River.
