Newport Beach Breaks Daily High Temperature Mark on Dry, Windy Sunday – Orange County Register

Newport Beach broke its daily high temperature record when the Santa Ana winds and dry relative humidity warmed much of southern California on Sunday, November 21, meteorologists said.

Thermometers peaked at 85 degrees on Sunday, breaking Newport Beach’s previous daily high of 1998 by one degree, the National Weather Service’s San Diego office said.

Conditions were also very dry along the Orange County coast as the relative humidity dropped to 5 to 10 percent, said Adam Roser, a meteorologist with the NWS.

The record breaking conditions were aided by brittle Santa Ana winds from the desert that gradually warmed as they passed through the mountains and down into the valleys, Roser said. For much of southern California, a red flag was applied on Sunday, which increases the risk of fast-moving forest fires, the NWS said.

While gusts of wind were sustained along the coast at around 20 miles per hour, higher gusts were observed in the mountain and pass areas of the Inland Empire. A gust of 67 mph and a gust of 57 mph from California State University San Bernardino was recorded near Arrowhead Springs, San Bernardino County, according to NWS.

In Los Angeles County, wind gusts of up to 70 miles per hour have been observed in the western San Gabriel Mountains, according to the NWS Los Angeles office.
