Tropical moisture fuels brutal humidity and heat across Southern California

Tropical Storm Marie offshore is pulling humid air into Southern California, triggering a multi-day heat wave with 90s to low-100s temperatures (even 105 inland) and muggy nights; forecasters warn of dangerous rip currents, higher surf, and elevated tides, with heat advisories expanding to multiple counties. Public health officials urge avoiding ocean swimming through midweek and staying hydrated, while residents seek cooling centers.
