The late-winter storm has unleashed significant rainfall amounts across San Diego County, leading to widespread flooding and storm damage. Rainfall amounts have varied across the region, with some areas experiencing record-breaking totals. The intensity and duration of the rainfall have overwhelmed drainage systems, resulting in significant flooding in many areas. Downtown San Diego, for example, saw over 3 inches of rain in a 24-hour period, leading to significant street flooding and impacting businesses.

• Specific rainfall totals:
  • Downtown San Diego: 3.2 inches
  • Mission Valley: 2.8 inches
  • La Jolla: 2.5 inches
  • Poway: 4.1 inches (highest recorded)
• Record-breaking rainfall: Poway's 4.1 inches surpasses previous records for late-winter storms in the area.
• Impact on infrastructure: Several roads have sustained damage due to flooding and erosion. Initial reports suggest damage to some smaller bridges and infrastructure.

Flooding and Road Closures

Extensive flooding across San Diego County has resulted in numerous road closures, creating significant challenges for commuters and emergency services. Many low-lying areas experienced significant inundation, with some residential areas reporting significant water damage. The sheer volume of water has overwhelmed storm drains, leading to prolonged flooding in several key areas.

• Major road closures: Interstate 805 experienced temporary closures near the Mission Valley area. Several surface streets in downtown San Diego and coastal areas were also impassable due to flooding.
• Detours and alternative routes: Traffic has been significantly impacted, with considerable delays reported across the county. Alternative routes are being actively promoted by local authorities.
• Rescues and evacuations: While no major evacuations have been reported, several water rescues have been conducted by emergency services.

Impact on Daily Life and Local Businesses

The heavy rain and subsequent flooding have significantly impacted daily life in San Diego. School closures were widespread, impacting thousands of students and families. Businesses, particularly those in low-lying areas, have experienced disruptions due to flooding, power outages, and reduced foot traffic. The transportation system has also felt the impact, with delays and cancellations reported on public transportation.

• School closures: Schools were closed for two days across many districts due to dangerous road conditions.
• Business disruptions: Many small businesses near the coast reported significant losses due to flooding. Retail stores and restaurants experienced reduced sales due to the challenging weather conditions.
• Impact on transportation: Public transport systems faced numerous delays and cancellations due to flooding and road closures.

Potential for Further Impacts

The potential for further impacts remains a significant concern. The saturated ground increases the risk of mudslides, especially in hillside areas. Continued heavy rainfall could exacerbate existing flooding and lead to further road closures and power outages. Local authorities are closely monitoring the situation and have issued warnings about potential dangers.
