SAN DIEGO (KGTV) -- Portions of San Diego County are gearing up for more dry, windy weather as a red flag warning and potential power outages loom.
According to the National Weather Service, the warning goes into effect from 4 a.m. Monday through 10 p.m. Tuesday for the mountains and valleys.
The agency says east winds of 20 to 30 miles per hour are expected, with gusts up to 50 miles per hour and isolated gusts up to 60 miles per hour.

Humidity will also be low, with values around 10%, the agency said Sunday.
“Any fires that develop will spread rapidly. Outdoor burning should be avoided,” the National Weather Service said.
SDG&E warned customers to prepare for the red flag warning, adding that it has alerted about 50,483 customers that they could be without power starting Monday night and lasting until Wednesday, depending on the severity of winds.
"Our crews remain on high alert and stand prepared to respond as needed to the next round of Santa Ana winds expected to impact our region. With our customers just now recovering from disruptive Public Safety Power Shutoffs (PSPS) due to the last Red Flag Warning, we hope Mother Nature will be kind to our region in the coming days and weather conditions improve," the company said.
SDG&E customers in several areas of the county already endured outages last week after the first round of high winds. The company said that the last of the approximately 70,000 customers who experienced outages had their power restored on Saturday morning.
