An uptick in Santa Ana winds Wednesday afternoon through Thursday, combined with critically dry vegetation and low humidity, will result in elevated to locally critical fire weather conditions in San Diego County through late Thursday.

Forecasters say the third windstorm of January will focus much of its energy on the region during one of the driest periods on record.

Wildfires in San Diego have led to mandatory evacuations in the area on Tuesday. Officials tell FOX News that two wildfires are burning in San Diego County, with strong Santa Ana winds creating "dangerous fire conditions." RELATED: Why are winter wildfires happening in Southern California?

Forecasters say weaker winds will hit on Saturday night and Sunday, and that there will be no relief until the county gets rain.
