...THIS IS A PARTICULARLY DANGEROUS SITUATION FOR IN AND IMMEDIATELY ADJACENT TO THE FOOTHILLS, BETWEEN 5500 AND 9000 FEET, FOR BOULDER AND JEFFERSON COUNTIES ON FRIDAY... Strong west winds, sustained 45-55 mph with gusts upwards of 85- 105 mph, are expected in the foothills of Larimer, Boulder and Jefferson Counties beginning early Friday morning. Relative humidity values are expected to drop into the low teens, possibly upper single digits. While Red Flag conditions, critical fire weather, are expected across a larger area in northern Colorado, the most extreme conditions are expected to be along Highway 93 from Jefferson County into Boulder County and along US-36 north of Boulder to the Larimer County line and westward. There will be a high 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. Such conditions may be a longer duration than usual, with potential for low humidity to extend well into the evening hours. * AFFECTED AREA...Fire Weather Zones 238, 240, 241, 242 and 243. * TIMING...From 10 AM this morning to midnight MST tonight. * WINDS...West 15 to 25 mph with gusts up to 60 mph possible west of I-25, and gusts to 40 mph possible along and east of I- 25. * RELATIVE HUMIDITY...As low as 12 percent. * IMPACTS...Conditions will be favorable for rapid fire spread. Avoid outdoor burning and any activity that may produce a spark and start a wildfire.

Middle River is a locality in the Australian state of South Australia located on the north coast of Kangaroo Island overlooking Investigator Strait about 162 kilometres (101 miles) south-west of the state capital of Adelaide.Its boundaries were created in March 2002 for the “long established name” and include the following shack sites - Middle River Shack Site and King George Shack Site. In 2011, a portion of Middle River was excised and added to the adjoining locality of Western River.The locality includes the watercourse called the Middle River and the associated water storage facility, the Middle River Reservoir.Land use in the locality is principally for agricultural purposes with activity limited on both the coastline to the north and on land at the locality’s southern boundary respectively for conservation purposes and for the protection of the drainage basin supplying the Middle River Reservoir.Middle River is located within the federal division of Mayo, the state electoral district of Mawson and the local government area of the Kangaroo Island Council.
