Strong Santa Ana winds are expected to develop across most of Los Angeles County late Sunday night into Monday, likely the strongest and most widespread Santa Ana event we have seen so far this season, the National Weather said today.

The strongest winds are expected late Sunday night into mid-afternoon Monday, when damaging gusts of up to 40 miles per hour could sweep across Pasadena.

The downslope winds will bring rapid drying, with humidities falling into the teens late Sunday night and early Monday morning, followed by widespread single-digit humidities by late Monday morning and continuing through Tuesday. This will elevate the danger of fire, the NWS said.

Any new fire ignitions under Santa Ana conditions will have the potential for rapid fire growth and extreme fire behavior, the forecasters warned.

The NEWS said Damaging winds could blow down power lines and large objects such as trees. Power outages are possible.
