Story summary

Tropical Storm Rachel, initially predicted by the National Weather Service to hit Baja California before changing course, ultimately brought significant damage to southern California in October 2026. The storm caused widespread coastal flooding and high surf that damaged homes along beaches from San Diego County to Long Beach and Newport Beach. Waves up to six feet and intense swells led to partial destruction of oceanfront properties, including the beachfront mansion of Olympian Paris Porter in Long Beach's Alamitos Peninsula, which had been rented by her and her husband RJ Porter since they got married there. The Porters shared videos showing their home crumbling into the sea, expressing deep sadness over the loss while highlighting the broader impact on coastal communities already hit by previous storms earlier that month.
