...CRITICAL FIRE WEATHER CONDITIONS FRIDAY... Critical fire weather conditions over the northeast plains will gradually ease into this evening. Strong winds will redevelop in the foothills overnight, with high winds spreading slowly east across the nearby adjacent plains west of I-25 through the afternoon. Extremely high wind gusts of 85-100 mph combined with humidities dropping into the 10-20 percent range will create potential for fast moving wildfires, should any new starts occur. Winds toward I-25 and eastward will be slower to develop, and also speeds will be considerably lighter. That said, gusts of 25-40 mph are still expected to combine with very low humidity and cured grasses to support critical fire weather conditions. Areas farther east into eastern Adams, Arapahoe, Elbert, and Lincoln counties have more uncertainty if those winds even develop, so those locations remain under a Fire Weather Watch. Such conditions may be a longer duration than usual, with potential for low humidity to extend well into the evening hours. The National Weather Service in Denver has issued a Red Flag Warning for wind and low relative humidity, which is in effect from 10 AM Friday to midnight MST Friday night. The Fire Weather Watch is no longer in effect. * AFFECTED AREA...Fire Weather Zones 238, 239, 240, 241 and 243. * TIMING...From 10 AM Friday to midnight MST Friday night. * WINDS...West 20 to 35 mph, with gusts up to 80 mph or more immediately next to the foothills. Gusts closer to 40 mph along and east of I-25. * RELATIVE HUMIDITY...As low as 8 percent. * IMPACTS...Conditions will be favorable for rapid fire spread. Avoid outdoor burning and any activity that may produce a spark and start a fast moving wildfire.

It is known for its crystal-clear waters and is a popular spot for recreational activities such as swimming, kayaking, and fishing. The river is named after the Spanish word for "white," as the limestone riverbed gives the water a milky appearance. The river also has a rich history, as it was once used by Native Americans and early settlers as a source of water and transportation. In terms of hydrology, the Blanco River is known for its flash flooding, which can be dangerous for those in the area. There are several reservoirs and dams along the river, including the Blanco and Wimberley Dams, which are used for agricultural purposes and to control flooding.
