Heavy rain and coastal flooding hit Los Angeles over Labor Day weekend as the remnants of Hurricane Marie moved inland from the Pacific. The weather event, which lasted from September 5 through September 7, marked an uncommon occurrence of September precipitation for the region.
The storm produced heavy rain across the city and along the coastline, leading to flooding in low‑lying areas and near the beach. Coastal streets saw water encroach on roadways, and some neighborhoods experienced temporary inundation.
Meteorologists identified the moisture from Hurricane Marie as the primary source of the rainfall. The storm, which had weakened after moving northward along the coast, still carried enough moisture to generate significant precipitation over the Los Angeles basin.
September rain is atypical for Los Angeles, which normally experiences dry, warm conditions during the early fall. The event therefore surprised many residents and prompted local authorities to issue flood warnings and advise caution near shorelines.
At the same time, the city was bracing for a mid‑week heat wave expected later in the week. Residents who had been preparing for high temperatures found their plans altered by the unexpected rain and flooding.
Authorities monitored water levels throughout the weekend and began cleanup efforts as the rain subsided. The brief but intense storm highlighted the lingering influence of tropical systems even after the official hurricane season has ended.
