...Smoke Impacts to Continue as Thunderstorm Risks Increase...


* Widespread thick smoke, mainly from the Dixie Fire, will
  continue to impact the region at least through Monday, and
  possibly Tuesday. There will be periods late in the day today
  and Monday where air quality could improve somewhat around Reno-
  Tahoe and the Eastern Sierra. However for the most part you
  should expect poor air quality to persist, especially at night
  and in the mornings.

* Limit the intensity and duration of outdoor activities. Poor air
  quality could result in postponed or cancelled outdoor events.


* A rather solid monsoon moisture surge will bring increasing
  thunderstorm chances to the area today through much of the
  coming week. Specifically for today the best odds are in the
  Eastern Sierra between Tahoe and Mammoth, with thunderstorms
  possible Monday, Tuesday, and Wednesday afternoons over more of
  the region including Reno-Tahoe, Fallon, and Susanville.

* There are also indications of a cluster of pre-dawn
  thunderstorms moving through early Tuesday morning, which given
  the unusual time of day, could catch many people off-guard.

* A significant concern with these storms is the potential for
  heavy rainfall and flash flooding on recent burn scars such as
  the Beckwourth Complex and ongoing fires such as the Tamarack
  Fire. It only takes 5-10 minutes of heavy rains to result in
  debris flows on these burn areas. Additional impacts include
  outflow winds to 50 mph, lightning with new fire starts outside
  storm cores, and small hail.
