Rancho Cucamonga – The South Coast Air Quality Management District (AQMD) issued a smoke advisory due to the conditions caused by the Etiwanda Fire. This wind-driven brush fire started Wednesday, and has currently burned over 1,000 acres. The air quality impact from the blaze has signaled concern for Diamond Bar, Walnut, La Verne, Claremont and Pomona. With the fire being only 10 percent contained due to the extreme wind conditions prevalent throughout the week, as well as high heat and low humidity, citizens are advised to avoid unnecessary activities outside.
At this time only one home has been damaged, but air conditions have caused many schools to close due to air and safety concerns. Mandatory evacuations for nearly 1,700 homes were issued on Wednesday, but lifted on Thursday. Schools, including Alta Loma High School, Banyon Elementary, Caryn Elementary, Etiwanda High School, Golden Elementary, Day Creek Intermediate, Los Osos High School, Rancho Cucamonga High School, and Chaffey College, remained closed on Thursday as well.
Santa Ana wind conditions always bring fire concerns, and this season is no exception. The initial cause of the Etiwanda Fire is still under investigation.
