While most of California will miss out on Rosa’s soaking rain, a storm on its heels will bring the first measurable rain since May to San Francisco, Los Angeles and other cities Tuesday into Wednesday. In California, the rain and flood risk associated with Rosa is expected to remain confined to the state’s southeastern corner early this week. Rough seas stirred up by Rosa will still continue to plague Southern California through Monday. Rip currents can endanger surfers or anyone who attempts to enter the water, and minor coastal flooding may occur at high tide.
