The National Weather Service (NWS) has issued a Red Flag Warning for much of eastern San Diego County, effective from 4 p.m. Monday through 6 p.m. Wednesday. This warning comes amid a new wave of Santa Ana winds, which are expected to create critical fire weather conditions in inland areas.

San Diego County is currently experiencing its driest start to the rainy season in 174 years, further exacerbating wildfire risks.

Key Weather Conditions

Strong Winds:

Gusty easterly winds up to 40-60 mph in mountain passes and valleys.

Increased risk of wind-driven wildfires.

Low Humidity:

Relative humidity expected to drop to 5-10% during the day.

Poor recovery overnight with humidity remaining low.

High Temperatures:

Warmer than average weather will persist, adding to fire risk.

Impacts

Wildfire Risk:

If a fire ignites, it could spread rapidly due to strong winds and dry vegetation.

Critical areas include inland valleys, mountains, and other high-risk zones.

Power Outages:

San Diego Gas & Electric (SDG&E) has notified 54,937 customers across the county about potential power shutoffs starting Monday evening.

Shutoffs aim to reduce the risk of power-line-sparked wildfires in high-risk areas.

Air Quality:

Smoke from wildfires in Los Angeles County has drifted into San Diego, prompting smoke advisories in some areas.

Dust and particulate matter from the winds have also degraded air quality.

Health Risks: Vulnerable groups, including children, the elderly, and those with respiratory conditions, should minimize outdoor exposure.

Affected Areas

The NWS Red Flag Warning Map highlights the following areas:

San Diego County inland mountains and valleys.

Riverside County mountains.

Specific neighborhoods identified by SDG&E for potential power shutoffs.

Air Quality Alert areas include parts of:

Los Angeles County (due to wildfire smoke).

Eastern Riverside County (due to windblown dust).

San Diego officials and agencies are urging residents to take the following steps:

Evacuation Readiness:

Prepare to evacuate if you live in areas under the Red Flag Warning.

Wildfire Safety Tips:
