...FIRE WEATHER WATCH REMAINS IN EFFECT FROM TUESDAY AFTERNOON
THROUGH WEDNESDAY EVENING FOR THUNDERSTORMS AND NEW FIRE STARTS
TUESDAY FOLLOWED BY GUSTY WINDS AND LOW HUMIDITY WEDNESDAY...
* Affected Area...Fire Zone 270 Surprise Valley California, Fire Zone 271 Western Lassen, Eastern Plumas, Eastern Sierra, and Eastern Nevada Counties, Fire Zone 278 Eastern Lassen County, Fire Zone 420 Northern Sierra Front including Carson City, Douglas, Storey, Southern Washoe, Western Lyon, and Far Southern Lassen Counties, Fire Zone 423 West Humboldt Basin in Pershing County and Fire Zone 458 Northern Washoe County.
* WINDS...For Tuesday: West winds 10-20 mph with gusts to 30 mph with outflow winds near thunderstorms to 50 mph. For Wednesday: West winds 15-25 mph with gusts to 35 mph.
* HUMIDITY...Afternoon humidities between 11 and 17 percent each day. Recoveries Tuesday night 50-70 percent in most valleys with 25-35 percent on mid-slopes.
* THUNDERSTORMS...Scattered but mainly wet and slow moving storms Monday, becoming faster moving and more prone to new fire starts Tuesday. No thunderstorms forecast Wednesday in the watch area.
* IMPACTS...This is a classic fire weather pattern with lightning potentially creating new fires followed by thunderstorm outflows, gusty zephyr winds, and drier air resulting in fire spread. Be prepared for a busy period of new fires if the forecast pans out.
* CONFIDENCE...Confidence in this scenario remains medium as predicting thunderstorm coverage and impacts a few days out can be an iffy proposition.
Avoid outdoor activities that can cause a spark near dry vegetation, such as yard work, target shooting, or campfires. Follow local fire restrictions. Check weather.gov/reno for updates and livingwithfire.info for preparedness tips.
