A potential Public Safety Power Shutoff event that could possibly impact parts of the City of Winters. PG&E meteorologists are tracking weather conditions for a possible PSPS event beginning Tuesday evening, 8/17 at 10:00 pm into Wednesday morning , 8/18 at 10:00 am. To be clear, this is an estimated time frame given the information we have now. The estimated number of impacted customers is 100 at this time.
Weather forecast models indicate that an upper level weather system will progress through the Pacific Northwest Tuesday into Wednesday and produce dry, northly winds across Northern CA. The northerly winds are expected to increase starting Tuesday night starting approximately at 9 pm across northern Counties, reach the Northern Sierra and Bay Area overnight Tuesday into Wednesday before tapering off near noon on Wednesday. Weaker northerly winds are also possible late Wednesday into Thursday. High resolution forecast models are indicating potential for maximum wind gusts from 30 – 45 mph with isolated gusts to 50 mph. Relative humidity values during the event are expected to be from 15 – 30% in general. Fuels are also historically dry in some areas and very susceptible to new fire ignitions. The entire area under PSPS consideration is also in extreme to exceptional drought at this time.
I have attached a map to this email so you can see the areas our PG&E meteorologists have identified at this time. Also, our Public Safety Specialist, Patrick Ellis, has been in touch with your County OES team regarding this potential PSPS event as well.
As I receive more information, I will be sure to keep you informed. Again, this is all preliminary, but I wanted to make sure you had a proper heads up before the possible PSPS event occurs.
