The NWS has issued an excessive heat warning for the region that will be in effect from eleven a.m. Saturday to eleven p.m. Sunday. Downtown Santa Rosa is expected to see a high of 91 degrees today, then high 90’s both tomorrow and Sunday.
Also, the Bay Area is under a Spare the Air alert today. High levels of smog are expected due to this weekend’s heatwave, meaning some could find it hard to breathe.
