As wildfires continue raging across the Southland, the hot and dry weather that's been working against firefighters in recent days is expected to shift in their favor, with rain expected by Monday , according to the National Weather Service.
Dropping temperatures, increasing humidity levels and a strong likelihood of rain in the coming days will come as a welcome change to firefighters who have been battling massive blazes across Southern California, from Ventura to Riverside counties.
Following scorching heat and single-digit humidities in recent days, "Today, the winds have shifted back onshore, so relative humidities have come up quite a bit," NWS Meteorologist Scott Sukup said.
Humidity levels were expected to climb beyond 50 percent Saturday, and continue increasing through the week, Suskup said.
High temperatures across the Southland will also drop as the week progresses, he added, falling to about 70 degrees by Sunday, and into the 60s on Monday and Tuesday.
"We could have some showers as early as (Sunday) afternoon, with the best chance of rain Sunday night into Monday. "
Though forecaster placed the likelihood of rain Monday at 60 to 70 percent, it was expected to come in the form of showers, rather than a significant downpout.
"It should dry out my mid- to late-week as that low pressure system moves to the east,' Sukup said, pushing high temperatures back up into the low- and mid-70s Wednesday through Friday.
The smoke from the regional wildfires was creating having a negative affect on air quality.
The Ventura County Air Pollution Control District warned Friday that air quality levels had become "unhealthy" and issued an advisory Friday stating that air quality levels have reached an "unhealthy" range, and that it was expected to remain that way through Monday.
And the wafting smoke, combined with that of other regional wildfires, was effecting neighboring counties as well, officials said.
Due to fires burning in Glendale and Ventura County, " "Smoke is adversely impacting the air quality for the San Fernando Valley, West San Gabriel Valley and the northwest coast of Los Angeles County," County of Los Angeles Department of Public Health officials said in a written statement.
"In all areas of visible smoke or where there is an odor of smoke, all individuals are urged to be cautious and to avoid unnecessary outdoor activities," according to DPH Director of Public Health and County Health Officer Dr. Jonathan Fielding.
Schools and sports organizations in smoky areas were advised to suspend outdoor physical activities such as physical education and sports, "until conditions improve," he added.
Sensitive individuals throughout Los Angeles County, including those with heart disease, asthma or other respiratory illnesses, were advised to avoid strenuous activities and try to stay indoors even in areas were smoke and ash are not visible, and there is no odor of smoke.
"It's difficult to tell where ash or soot from a wildfire will go, or how winds will affect the level of dust particles in the air, so we ask all individuals to be aware of their immediate environment and how it might affect their health."
