The last time it was this dry in January, there were barely more than 500 people in San Diego. The year was 1850, and only a quarter-inch of rain had fallen in six months. It made the region ripe for wildfire — but that wasn’t much of a concern. The city’s population was clustered along the coast, far from the backcountry, where most fires burned.

A critical fire threat will continue across County as Santa Ana winds and dry conditions persist through early Friday, according to the National Weather Service.

Since Jan. 8, one wave after another of fierce Santa Anas have blown through Southern California. Thus far, the San Diego area has escaped the devastation seen in the Los Angeles areas by wind-whipped blazes that leveled homes and forced evacuations.

Scattered showers are expected early this week for San Diego County, with a slight chance of thunderstorms in the afternoon into Monday morning for the coast, valleys and mountains. A winter weather advisory will remain in effect until at least 4 p.m. Monday, with chances of snowfall for county mountains, according to the National Weather Service.

San Diego County remains under the grip of another round of moderate to strong Santa Ana winds, paired with extremely dry air, elevating critical fire weather concerns.
