Expected Temperature Drop & Rainfall

Significant Cooling

Expect a dramatic drop in temperatures, well below the average for this time of year. This significant cooling will be felt across the county, with variations depending on location:

• Coastal areas: Prepare for temperatures dipping into the low 50s (°F) – bringing a noticeable chill to the usual San Diego warmth. Pack layers and be prepared for cooler-than-normal beach conditions.
• Inland valleys: Inland regions of San Diego County can expect even lower temperatures, potentially reaching the 40s (°F). Frost is possible in some areas, so protect sensitive plants.
• Mountain areas: The mountains will experience the most significant temperature drop, with temperatures potentially falling below freezing. Frost and icy conditions are a real possibility, impacting travel and outdoor activities. Check road conditions before venturing into mountain areas.

Heavy Rainfall Potential

The incoming storm system is predicted to bring substantial rainfall, raising concerns about potential flooding in low-lying areas.

• Rainfall Accumulation: Depending on the location within San Diego County, rainfall accumulation could range from several inches to over a foot in higher elevations. Be aware of potential flash flooding, especially in areas with poor drainage.
• Flash Flood Warnings: Stay alert for flash flood warnings issued by the National Weather Service. These warnings indicate an imminent threat of rapidly rising floodwaters and are crucial to heed.
• Avoiding Flooded Areas: Never attempt to drive or walk through flooded areas. The depth of water may be deceiving, and currents can be incredibly strong. Turn around, don't drown.
