LOS ANGELES (CNS) - Southern California will again swelter today and  amid record-heat, bone-dry conditions and erratic winds -- the elements that  create a high risk of wildfires.

A Red Flag Warning signifying the presence of wildfire conditions will  again be in effect in much of Ventura and Los Angeles counties today but this  time, not in Orange County, where the warning was allowed to expire Wednesday.  The warning also continues to exclude the Antelope Valley.

Today's winds will be somewhat weaker than earlier this week but gusts  of between 25 and 35 miles per hour are forecast for this morning across the  valleys and mountains, according to the National Weather Service.

The region has been swept by Santa Ana winds since Sunday, but a gradual  transition to onshore winds is expected through this afternoon, the National  Weather Service reported.

``The transitioning winds will create erratic and gusty winds Thursday  morning through Thursday afternoon,'' warned an NWS advisory.

``The combination of erratic winds, record-breaking temperatures ranging  15 to 30 degrees above seasonal normal and single-digit humidity will combine  to create red flag warning conditions across most of Ventura and Los Angeles  counties.''

More record-high temperatures were expected today. Five records for a  May 14 were set in Los Angeles County Wednesday: 

-- 96 degrees at Los Angeles International Airport, breaking the record of 87  set in 1967;

-- 99 degrees at downtown Los Angeles/USC, breaking the record of 96 set in  1890;

-- 101 degrees at Long Beach Airport, breaking the record of 93 set in 1970; 

-- 96 degrees at UCLA, breaking the record of 87 set in 1979 and tied last  year; and

-- 83 degrees at Sandberg, breaking the record of 82 set in 2006 and tied in  2013.

The NWS forecast sunny skies today and highs of 85 on Mount Wilson; 90  in San Clemente; 92 in Newport Beach; 93 in Avalon and Laguna Beach; 95 in  Palmdale and at LAX; 96 in Lancaster 100 in downtown L.A.; 101 in San Gabriel,  Woodland Hills, Long Beach, Mission Viejo and Anaheim; 102 in Saugus, Pasadena  and Fullerton; and 103 in Burbank and Yorba Linda.
