The primary risks associated with the storm include heavy rainfall, flash flooding, and coastal flooding, especially along south-facing shores. Dangerous waves and rip currents are expected to begin as early as Friday, posing a threat to beachgoers. Inland areas, particularly mountainous regions, may experience flash floods, landslides, and debris flows if heavy rainfall occurs. While the storm is not expected to bring hurricane-force winds, it could still cause damage similar to a strong winter storm (Los Angeles Times, 2026-09-01).
