658 WWUS85 KLKN 172115 RFWLKN URGENT - FIRE WEATHER MESSAGE National Weather Service Elko NV 215 PM PDT Thu Jun 17 2021 ...Fire Weather Watch for Dry Lightning on Friday...

The National Weather Service in Elko has cancelled the Fire Weather Watch. Isolated dry thunderstorms are expected to reach into southern 469 and 470 and will still pose a hazard. However, the amount and coverage of these thunderstorms is not sufficient to warrant any further headline products. Thus the Fire Weather Watch is cancelled and is no longer in effect for these zones. $$ NVZ425>427-181515- /O.UPG.KLKN.FW.A.0004.210618T1800Z-210619T0300Z/ /O.NEW.KLKN.FW.W.0005.210618T1800Z-210619T0300Z/ White Pine and Northeast Nye Counties-Northern Nye County-Mojave- Central Nevada-Toiyabe- 215 PM PDT Thu Jun 17 2021 ...RED FLAG WARNING IN EFFECT FROM 11 AM TO 8 PM PDT FRIDAY FOR DRY THUNDERSTORMS AND GUSTY OUTFLOW WINDS FOR FIRE WEATHER ZONES 425, 426, AND 427...

A combination of strong winds, low relative humidity, and warm temperatures can contribute to extreme fire behavior. && $$
