One of the comments by IMT spokesperson was “we are expecting seven (7) miles of fire growth tomorrow”. Winds out of the west 40 mph with gusts exceeding 50 mph.

The possible growth is based on modeling and IF lines don’t hold. Just want to point out that it is possibility.

I was doing some research about the Particularly Dangerous Situation Red Flag warnings. It has been used 7 times since 2017. Of these 7 times, 5 have been issued in Reno. The other 2 were in Texas and Oklahoma.

Did you happen to see what CA might have had? Seems like the Santa Ana winds might elicit this type of warning.

There has never been one issued for SoCal. The ones in the Reno areas have included the eastern Sierra in California.

PDS warnings are mostly issued for tornado warnings.

Here is the link to the site. IEM :: Particularly Dangerous Situation (PDS) Listing

As I noted to friends who have moved out of the area, seven miles will bring the danger zone to South McCarran Blvd. – the “ring road” which encompasses Reno / Sparks.

In fact, “Evacuation Warning” (yellow) zones were expanded today after the PDS was declared. (As metrohazmat noted – it has been declared here in the region before.). Between terrain and the unique wind patterns, this conflagration has the potential to spot a good distance from origin into the urban interface.

The 1 pm report from the Galena RAWS site show the winds are increasing to 22 mph sustained with gust to 37 mph. The slide mountain camera and the Calaveras camera aren’t showing much smoke production. Hoping it stays that way.

The Davis Fire remained within the containment lines today and containment increased slightly from 31% to 37%. Acreage is 5,824. The work put in yesterday and last night paid off. Evacuations have not changed. Weather is favorable tonight with RH getting up to ~60% and winds dropping to single digits out of the NW. Fixed wing and helicopters should join the fight tomorrow.

I have to second this. Between this site and WD I could keep track of what the fire was doing. Had some friends that were evacuated off the Mt Rose Hwy. I could keep them informed of what was going on with the fire. The were in a hotel for 5 days.They were able to go home today and their house is still standing.
Thanks to the hard work of Air, Ground crews and all involved.
