Expected Temperature Drop & Impact

A significant decrease in temperatures is expected across San Diego County. Nighttime lows will be unusually cold for this time of year, potentially reaching near-freezing levels in some inland areas. This unexpected drop in San Diego weather could lead to frost in certain valleys and inland communities. This San Diego weather alert emphasizes the importance of preparedness.

• Pack layers for warmth: Dress in layers to adjust to fluctuating temperatures throughout the day. Include hats, gloves, and scarves.
• Protect sensitive plants from frost: Cover vulnerable plants with blankets or sheets to prevent damage from freezing temperatures. Consider bringing potted plants indoors.
• Check on elderly neighbors and vulnerable individuals: Ensure that those who may be more susceptible to the cold have adequate warmth and are safe.
• Be aware of potential for hypothermia: Hypothermia can occur even in relatively mild temperatures if you are wet or exposed for extended periods. Know the signs and seek help immediately if needed.

Heavy Rainfall and Potential Flooding

Heavy rainfall is expected, particularly in the mountainous regions of San Diego County. This increased precipitation significantly raises the risk of flash flooding in low-lying areas and canyons. Areas with recent burn scars are especially vulnerable to mudslides and debris flows. This San Diego weather alert underscores the need for caution near waterways.

• Avoid driving through flooded areas: Never attempt to drive through floodwaters. Turn around, don't drown. The depth of water may be deceiving, and even a small amount can sweep a vehicle away.
• Monitor local news for flood warnings: Stay updated on the latest weather reports and flood warnings issued by local authorities. Be aware of any evacuation orders.
• Clear drains and gutters around your property: Ensure that water can flow freely away from your home to minimize the risk of flooding.
• Be aware of rising water levels near rivers and streams: Stay away from riverbanks and stream beds as water levels can rise rapidly during heavy rainfall.

Strong Winds and High Surf

Strong winds are anticipated throughout San Diego County, with potential for damaging gusts. A high surf advisory is in effect for coastal areas, posing risks to beachgoers and those living near the coast. The strong winds also increase the risk of downed power lines and property damage. This San Diego weather alert highlights the need for securing loose objects outside.

• Secure loose outdoor objects: Bring in any loose furniture, patio umbrellas, or other items that could be blown away by the wind.
• Avoid being near the coast during high surf: Stay away from beaches and cliffs during high surf conditions. Strong waves can be dangerous and unpredictable.
• Report downed power lines to authorities immediately: Do not approach downed power lines; report them to your local utility company or emergency services.
• Be prepared for potential power outages: Have flashlights, batteries, and a fully charged cell phone ready in case of power outages.

Specific Areas of Concern

Mountain communities in eastern San Diego County are expected to experience the most significant snowfall accumulation and increased risk of flooding. Coastal areas, particularly those with cliffs and bluffs, are at high risk for coastal erosion and high surf impacts. Residents in these areas should take extra precautions.
