Tropical storm Hilary, having weakened from a Category 1 hurricane, is speeding up while pushing into Southern California Aug. 20, prompting evacuation warnings and cancellation of flights, classes, and sports games in some regions, bringing a stretch of rainfall expected to last through Monday.
Residents are asked to remain indoors as the tropical storm will likely bring “catastrophic and life-threatening” flooding to the region, according to National Weather Services (NWS).
