Update: Red Flag Warning For The Northern San Joaquin Valley
A Red Flag Warning is in effect for the Northern San Joaquin Valley until 5 PM Friday.
Fifteen to twenty-five mph winds will continue at times, with gusts up to forty-five mph.
The minimum daytime humidity will range from five to twenty-five percent. The maximum overnight humidity tonight will be between fifteen and forty percent.
A Red Flag Warning means that critical fire weather conditions are either occurring now, or will shortly. A combination of strong wind, low relative humidity, and warm temperatures can contribute to extreme fire behavior.
Additionally, the Mariposa County Air Pollution Control District has issued an Air Quality Alert for Mariposa County.
The Air Quality Alert will remain in effect until the nearby fires that are causing smoke over the county are extinguished.
Exposure to particle pollution can cause serious health problems, aggravate lung disease, cause asthma attacks and acute bronchitis, and increase risk of respiratory infections.
Residents are advised to use caution as conditions warrant. People with heart or lung diseases should follow their doctors advice for dealing with episodes of unhealthy air quality. Older adults and children should avoid prolonged exposure, strenuous activities or heavy exertion, as conditions dictate.
