Dense Fog Advisory for San Diego County

A dense fog advisory is currently in effect for San Diego County. Visibility is significantly reduced in many areas, dropping to less than a quarter mile in some locations. This thick fog is expected to persist throughout the morning and into the early afternoon. The combination of fog and cooler temperatures creates hazardous driving conditions.

• Areas with Densest Fog: Coastal areas, including the beaches of La Jolla, Pacific Beach, and Mission Beach, are experiencing the densest fog. Inland valleys may also see periods of reduced visibility.
• Driving in Fog: Reduced visibility dramatically increases the risk of accidents. Drivers should significantly reduce their speed, increase following distance, and use their headlights, even during daylight hours. Avoid unnecessary travel if possible.
• Pedestrian Safety: Pedestrians should exercise extra caution when walking or cycling. Consider using reflective clothing or carrying a flashlight to improve visibility.

Unseasonably Cool Temperatures in San Diego

San Diego is experiencing a significant drop in temperature, with lows expected to be considerably lower than the average for this time of year. We're looking at a noticeable shift from the typical warm, sunny days. Expect daytime highs to remain in the low 60s (°F) and overnight lows dipping into the upper 40s (°F) for the next few days. This is a significant departure from the usual comfortable temperatures San Diegans are accustomed to.

• Staying Warm: Layer your clothing to trap body heat and wear warm socks and hats. Warm beverages like tea or hot chocolate can also help maintain body temperature.
• Hypothermia Risk: Be aware of the symptoms of hypothermia (shivering, confusion, drowsiness) and seek medical attention if needed. Spend less time outdoors, particularly if you are elderly, have pre-existing health conditions, or are very young.
• Protecting Vulnerable Populations: Check on elderly neighbors, ensure children are dressed warmly, and bring pets inside to avoid exposure to the cold.

Chance of Rain and Associated Risks

While the probability of significant rainfall is moderate, there's still a chance of showers throughout the day. This could lead to slick roads and potential flooding in low-lying areas. The rain is expected to be light to moderate in intensity, but its duration may contribute to water accumulation.

• Flood-Prone Areas: Low-lying areas near rivers and streams are at increased risk of flooding. Residents in these areas should monitor the situation closely.
• Preparing for Flooding: Consider placing sandbags around your home to protect against potential flooding. Move valuable items to higher ground.
• Road Closures and Detours: Check local news and traffic reports for information on road closures and detours. Avoid driving through flooded areas.
• Landslide Risk: Residents in hilly areas should be aware of the increased risk of landslides due to saturated soil.
